Find the smallest number greater than n with the same digit sum as n Let's see the steps to solve the problem. Print NONE otherwise. Save a copy. An efficient approach is to iterate from n to 1. As others have pointed out, we know the answer lies in the range [1, len(A)+1], inclusively. 11. Whenever sum of elements between current start and end becomes greater than x, update the result if current length is Given a number N, find the smallest number that has same set-of-digits as N and is greater than N. If N is the greatest possible number with its set-of-digits, then print the same number N. The task is to find the least number not less than N which contains the equal number of digits A and B. By using our site, Find the smallest natural number $n$ such that rightmost digit is $6$ and when we deleted that digit $6$ and add it to the left of the number we get $4n$. = 9 n Given a number N, find the smallest even number E such that E > N and digits in N and E are same. But it takes a lot of time to calculate for higher values. In the second traversal, find the smallest element greater than x. If no such number k can be formed then print “-1”. This is what I have so far: Proof: The requested number must be at least N+1, this is why we increment. Then sort all of the digits to the right of Y in descending order. Take the 2nd number and compare it with max if the the 2nd number is greater than max then assign it to max else do nothing. Do the following for each digit of current number, if the digit is not zero, reduce it by one and change all other digits to nine to the right of it. Suppose that there was some digit, other than the lead digit, that was less than $9$then you could subtract one from the lead digit and add it to that digit and get a smaller solution, The ROWS(A$2:A2) function automatically generates n numbers, so you needn't type them anywhere in the sheet. It would be better to be consistent. Reverse Prefix of Word; 2001. But it takes forever to run with big values of n. I've changed your program to print i instead of result, and break out of the loop when it finds the first number (which logically must be the smallest):. My function, so far, can print the average and largest value of n amount of numbers entered by user but I'm stuck on finding the smallest value. Examples: Explanation: The next number greater than 218765 with same set In this python algorithm we will write a simple program to find the next smallest greater number than the given number using the same set of digits. Proven that you are given an unordered list of numbers, then you would need to sort the list first. It will find the two smallest integer in the set and print it out. Examples: Input: N = 4 Output: Smallest Palindrome = 1001 Largest Palindrome = 9999 Input: N = 5 Output: Smallest Palindrome = 10001 Largest Palindrome = 99999 Smallest N-digit Palindromic Number: On observing carefully, you will observe that for #greedy #competitiveprogramming #coding #dsa Hey, Guys in this video I have explained with code how we can solve the problem 'Find the smallest number with a Given two integers N and K (K<N), the task is to find the smallest number greater than K by removing digits from N.

Given a number num containing n digits. Examples: Input : Consider the minimal solution. 3. Bertrand's postulate (actually a theorem) states that if n > 3 is an integer, then there always exists at least one prime number p with n < p < 2n − 2. , to find the minimum value permutation of A greater than B. For example, if M = 100 and N = 11, then the smallest integer greater than 100 whose digits add up to 11 is 119. Examples: Input: N = 10 Output: 11 11 is the smallest prime number greater than 10. , thousands, hundreds, tens and ones or Given a positive integer N, the task is to find the smallest positive number made up of distinct digits having sum of its digits equal to N. Besides, Least Greater number with same digit sum Given a number represented in the form of an array such that each element of the array stores a single digit of the number. Otherwise, print "No". Your approach is almost correct. Example 2: Input: N = 20 Output: 2990000000000000000000. You have to create a function that takes a positive integer number and returns the next bigger number formed by the same digits: 12 ==> 21 513 ==> 531 2017 ==> 2071 If no bigger number can be composed using those digits, return -1: 9 ==> -1 111 ==> -1 531 ==> -1 I wrote a code to it after so many failures despite the exercise being pretty simple. See original problem statement here. I need to output -1 if there is no such number Q. For example, the decimal number 1 has a binary weight of 1, and the decimal number 7 (which is 111 in binary) has a binary weight of 3. Examples: Input : 100 Output : 455 Explanation: 4*5*5 = 100 and 455 is the smallest possible number. 10}, 10 different digits of which 1 s t place is filled in 9 ways, 2 n d place in 9 ways (since 0 can be included and first digit is not repeated) and so on n times. Given a number N, the task is to find the smallest Even number with N digits. This problem is asked in many Yes, it is possible to do it in O(n log n) time. Also, you made this function take an unsigned int, but then you drop the unsigned qualifier in isPrime. find sum of all n digit numbers that can be formed using these digits. A simple approach is to check every divisor within the range of 1 to the maximum element in the array. Count Number of Texts Given a number N and a number K, the task is to find the smallest number greater than or equal to N which is divisible by K. Examples : Input: n = 5Output: 8 Input: n = 17Output: 32 Input : n = 32Output: 32 Recommended PracticeSmallest power of 2 greater than or equal to nTry It! Method 1: Using lo We are given an number and we have to find the smallest pallindrome number greater than N which can be formed by using the same set of digits as in N. However, the return value shouldn't be min(seq[i]) but instead only seq[i]. Code: Given a palindromic number num having n number of digits. Examples: Input : 4697557964 Least Greater number with same digit sum Given a number represented in the form of an array such that each element of the array stores a single digit of the number. Example: Input: N = 10Output: 19Explanation: 1 + 9 = 10 = N Input: N = 18Output This problem is taken from hackerearth which is based on simple OR operatorproblem link https://www. Note: It is guaranteed that the input number N does not have all of its bits as set In this approach, we’ll utilize permutation to find the next greater number with the same digits as the input number. Examples: Input: x = 51, arr[] = [1, 4, 45, 6, 0, 19] Output: 3 Exp. You must output the smallest number greater than N with the same digit sum as N. If next greater number cannot be formed then print the original Given two numbers A and B, the task is to find the arrangement of digits of A such that it is just greater than the given number B, i. The only remark is 6 = 2*3. The problem is to find the next greater number using the same set of digits in num on the basis of the given precedence of digits. Let us call the prefix the initial 0/1 digits and suffix what comes after. Specify what you need: any consecutive integers or only even/odd ones. \text{n times} \times \text{sum of all n numbers}$$ Therefore, our ans for the question as follows: Try to solve this puzzle "Digit sum successor" (25+ languages supported). The idea is to increment the last digit that is not a nine by one to make it larger than the given number. com/practice/basic-programming/bit-manipulati Find smallest number with given number of digits and sum of digits in C - In this problem, we are given two values that are the sum (denoting the sum of digits) and digit (denoting the number of digits). If no such number exists, print -1. For each number, we calculate the sum of its digits. We have solved this using a Greedy approach in linear time. For example for N = 10, the first multiple of 10 with a digit sum 10 is 190 (1+9+0 = 10). Find the smallest number with 2**500500 divisors. Given a number n, find the smallest number that has the same set of digits as n and is greater than n. If found to be true, then print "Yes". Input: N = 11, K = 3Output: 12 Approach: Approach to solve Given an unsorted set of integers in the form of array, find minimum subset sum greater than or equal to a const integer x. e. Otherwise, ignore the first half of a, adjust k. This makes the number as big as possible, without making it bigger than the original. The task is to find the least number greater than the given number but having the sum of digits equal to the given number. To find the actual value of a digit from a character, subtract the ASCII value of ‘0’ from Given a number N as string, find the smallest number that has same set of digits as N and is greater than N. A naive approach is to iterate for all numbers from 1 to n and find out which number has maximum sum of digits. Once all permutations are generated, we iterate through the TreeSet to find the smallest number greater If one does not get such a digit, then it is not possible to find the next greater number. Given a positive integer N, the task is to check if the sum of the digits of N is strictly greater than the product of the digits of N or not. For example the precedence of digits is given as 1, 6, 4, 5, 2, 9, 8, 0, 7, 3 which simply means 1 < 6 < 4 < 5 < 2 < 9 < 8 < 0 < 7 < 3. Solve it. Examples: Input: N = 1234Output: NoExplanation:The sum of the digits of N(= 1234) is = 1 + 2 + fun is not a great name. Lastly, iterate over the left segment again and find the missing number by searching for the I have to create a function that takes a positive integer number and returns the next bigger number formed by the same digits: 59853 -> 83559 Please let me know if there are any better solutions. patreon. Constraints. If the sum matches the target, we increment the count. Example: M = 919 , N = 34. I am trying to find the smallest number if we are given the sum of its digits. Example 1: Input: n = 12 Output: 21 [Naive Approach] Using Two Nested Loops – O(n^2) Time and O(1) Space. Input: N = 19, S = 3 Output: 20 Explanation: Sum of digits of 20 is 2, which is less than 3. For n = 9, output is 19. Given an integer N ? 1, the task is to find the smallest and the largest sum of two N digit numbers. 22,3. Example: Input: 14Output: 3 5Explanation: 3 and 5 are consecutive prime numbers whose product is greater than 14. Note: There are several combinations possible, find only the pair whose minimum value is the smallest among all the minimum values of pairs and print the minimum element first. The idea is to use two nested loops. This way smallest integer > n with digit m This program takes two numbers M(<10k) and N (<100) and finds the smallest number greater than M whose sum of digits = N. Their product is 3 × 4 = 12, which is greater than N. Count Nodes Equal to Average of Subtree; 2266. Then it temporarily sets the smallest number to the first number in the list, and iterates through the list one by one to check the numbers in the list against the smallest number. Example: Input: 1 2 3 Output: 1332 Given a sorted list of numbers, I need to find the smallest number that is greater than a given number. Then, to find a number n such that n^2 is ending in 001, the only last 2 possible digits of n can be 51, 49, or, 99. Putting the following strip of code after the if code strip gives -1 for all inputs. Example of Given two integers N and K (K<N), the task is to find the smallest number greater than K by removing digits from N. Ex. The outer loop picks a starting element, the inner loop considers all elements (on right side of current start) as ending element. Examples: Input While if we turn the bits which are zero to 1 we find the numbers are 11 (1011) or 13 (1101) so if switch the lowest possible bit which is zero to 1 then we get the smallest possible number greater than N with only 1 bit different, in this case it is 11 (1011). Next take the 3rd number and compare it with max , if the 3rd number is greater than max assign it to max else do nothing. then create all permutations of those N digits. Required number = 7999 as 7+9+9+9 = 34 [Naive Approach] Linear Search – O(n*max(arr)) Time and O(1) Space. I tried with the following: numbers = [2, 4, 9, 2, 0, 16, Solved examples on Formation of Greatest and Smallest Numbers: 3. The number greater than N = 40 with the sum of their digits divisible by 5 are {41, 46, 50, 55, }. Example 1: Input: N = 5 Outptut: 500000 Explanation: Sum of digits of 500000 is 5 and divisible by 105. How can I optimize it? Starting from the right, you find the first pair-of-digits such that the left-digit is smaller than the right-digit. I am trying to write an algorithm that finds and smallest and largest value in an array, and the second largest and second smallest. Input: N = 1 Output: 3 Explanation: The integers are 1 and 2. Naive Approach: The simplest approach is to check every number greater than N and if the sum of its digits is divisible by M, increment the counter by 1. Input : 26 Output :-1 Source: Asked in Amazon Interview We will be provided with a number of n digits and we have to find the next greater number than n using the same set of digits, as in the number n. Examples: Input: S[] = {5, 2, 3}, N = 12 Output: 252 We can observe that 252 is formed using {2, 5} and is a multiple of 12 Input: S[] = {1, 3, 5, 7, 9}, N Solution. If n is the greatest possible number with its set of digits, report it. Then, we iterate over this left segment and mark the occurrences of each number x by negating the value at index (x – 1). The problem is to find the smallest palindromic number greater than num using the same set of digits as in num. If no such permutation is possible then print -1Examples: Input: A = 9236, B = 3125 Output: 3269 Explan Find the smallest number such that the sum of its digits is N and it is divisible by 10N. If no such number exists, print “-1”. While we considered optimizing the process by i Write a function that, for a given no n, finds a number p which is greater than or equal to n and is the smallest power of 2. For the other one, the problem is that you are overwriting the value of value with the for loop leading to 189 is the smallest number greater than 99 having sum of digits = 18. I need to input a number N and find the smallest integer Q such that the product of its digits is N. Step 2: Now start searching the right side of the above found digit 'd' for the smallest digit larger than 'd'. Given the sum of digits a and sum of the square of digits b . Input : n = 2 Output : 4 4! = 24 and 3! = 6, hence 4 is the smallest number having 2 As I mentioned in another question I've been teaching myself C out of of K. For example, if the input number is 534976, we stop at 4 because 4 is smaller than next digit 9. Input : N = 1000, S = 1 Output : 4 Upto 1000 only 4 numbers(1, 10, 100 and 1000) can produce 1 as their sum of digits. Note that the digits from the set can be used multiple times. If it is not possible to find any such number, then print "not possible". Any number is congruent with the sum of its digits modulo 9. Input. Examples: Input: N = 1 Output: Largest = 18 Smallest = 0 Largest 1-digit number is 9 and 9 + 9 = 18 Smallest 1 Python provides the frexp() and ldexp() functions in its standard math library. Formula 2. Thus, they are also regular numbers. the smallest prime number greater than N. So we're looking for pairs of digits in $\{2,3,\ldots,9\}$ whose product exceeds their sum by exactly $2$ (the number of digits $1$ we need to throw in). We will solve this using a greedy approach in O(M). Code Review: Find the smallest number greater than "n" with the same digit sum as "n"Helpful? Please support me on Patreon: https://www. – Given an integer N, find the smallest N digit number such that the sum of the square of digits (in decimal representation) of the number is also a perfect square. We know that a four digit number has four places, i. Taking Input Number as String. 2, 4. The more sensible question is "Find the smallest multiple of N which has the digit sum N". If the current number that it is checking is smaller than the smallest number variable, then it becomes the new smallest number. For example: If the given number is 12 then the next greater number using the same set of digits would be 21. Out of the digits 9, 7, and 5, the smallest digit larger than 4 is 5. The count of all these numbers can be computed recursively: if the number of digits N is 1, you will have either 0 or 1 such number; if N is bigger, you can compute the count of N-digit numbers in terms of counts of N-1 digit numbers. Note that the returned integer should fit in 32-bit integer, if there is a valid answer but it does not fit in 32-bit integer, return -1. Let's iterate over the array of prefix sums from left to right and maintain a The user should be able to enter any amount of integer. Examples: Input: arr[] = {2, 4, 6, 10, 2, 1}, K = 12 Output: 2 Explanation: All possible subarrays with sum 12 are {2, 4, 6} and {10, 2}. Perform these steps in the following order: Time Complexity: O(log 10 n), as we are iterating over all the digits. The number should not contain more than 100 digits. Examples: Input : The task is to find the smallest palindromic number greater than N using the same set of digits as in N. The next permutation of a positive integer is the smallest number greater than the number in question formed by permuting the number's digits I tried my hand at a grade XII Board exam program: Given two positive numbers M and N, such that M is between 100 and 10000 and N is less than 100, find the smallest integer that is greater than M and whose digits add up to N. There are {0, 1, 2,. Given a number N as string, find the smallest number that has same set of digits as N and is greater than N. If we do not find such a digit, then output is Not Possible. Smallest number whose sum of the digits is equal to the given number n Hot Network Questions Linear version of std::bit_ceil that computes the smallest power of 2 that is no smaller than the input integer Find next greater number with same set of digits in C - In this problem, we are given an element N.

The solution will always exist according to Goldbach’s Given a number n. For simplicity: Consider the length of number can be 20 at maximum. So the problem reduces to find a permutation of a number E1, that is greater than or equal to E1 (based on the value of e) and minimum. We can find Least Greater number with same digit sum Given a number represented in the form of an array such that each element of the array stores a single digit of the number. Input: N = 121320, K = 756 Output: 1120 Explanation: Among all the Your logic for the smallest will fail if all the input numbers are greater than zero. We can turn that into a set and take the minimum element in the set difference with A. arr[] = {1, 5, 10, 4, 7}, X = 4 Output: 6 6 is the smallest number greater than 4 which is not Again now sum of all no formed by permutations = Sum of all the numbers appeared like ‘a’ with their values = $$(n-1)! \times 1111. We need to find the smallest number with the same digit which is greater than N. We are now looking for a number greater or equal. The current_sum variable keeps track of the sum of elements in the current subarray. Throwing away the right part, incrementing the left part by adding one (instead of looping through every single digit) and "mirroring" the left part to the right after the increment makes the algorithm shorter and handles the case of all digits being 9 as well - at least as long the number is small enough to fit in an integer, which the question seems to imply. Chances are, these methods invoke special hardware instructions (such as converting integers to floating point and extracting the exponent bits from the IEEE 754 floating point format together with the fraction bits). hackerearth. Additionally, as per the question's requirements, it prints the number of digits in the printed number. N = 37 -> smallest number = 10. ; else, increase N by one and repeat the process. We need to find the next greater number with the same set of digits. Case 2: if N != 1 then answer will be (10^(N-1)) because the series of smallest even numbers will go on like, 0, 10, 100, 1000, 10000, 100000, . Approach: The problem can be solved using a greedy approach. The task is to find the number of way s in which the numbers that are greater than or equal to m can be added to get the sum n. A sum of a (L, R] subarray is prefixSum[R] - prefixSum[L]. These functions are borrowed from C. Write a program to accept the numbers M and N The code is working. Note: This method doesn’t work if there are duplicate elements in the array. Printing the smallest number and then printing the second smallest. Given a positive integer N, find the smallest integer greater than N that has the same binary weight as N. else { printf("-1"); break; } What am I doing wrong? We first have to realize that since n^2 must end in 00001, the units digit of n is either 1 or 9 because 1^2 = 1 and 9^2 = 81 (ends in 1). To obtain 'next' from ‘n’ we observe: In ‘n’, if we flip a bit from 0 to 1 then we must flip a bit from 1 to 0. Our task is to find the smallest number with a given number of digits and sum of digits. For example: How to find the smallest number with given digit sum s and number of digits d? Examples : Input : s = 9, d = 2 Output : 18 There are many other possible numbers like 45, 54, 90, etc with sum of digits as 9 and number of digits as 2. Given a number N (greater than 2 ). The idea is to first move all positive integers to the left side of the array. Output. And in this case, the number is either $3$ or composite. public static int getSmallestNumber Given the sum of digits a and sum of the square of digits b . ; join them into a String and put in a TreeMap<String>; if there exists a next higher value of the original N digits, return the new value with the new ending concatenated to the original. Let's take a look at prefix sums. Given integer N and integer S, the task is to find the smallest number greater than or equal to N such that the sum of its digits does not exceed S. eg:- Our set is {4 5 8 10 10} and x=15 so the minimum subset sum closest to x and >=x is {5 10}. Digit Sum Calculator. We must replace the first digit of the suffix by a zero and set a larger prefix. I have an integer value N which may contain large prime factors and I want to round it up to a number composed of only Given a number x and an array of integers arr, find the smallest subarray with sum greater than the given value. Write a function that, for a given no n, finds a number p which is greater than or equal to n and is the smallest power of 2. Example 1: Input: N = "35453" Output: 53435 Explanation: Next higher We use cookies to ensure you have the best browsing experience on our website. Using Iterative Approach – O(n*10^n) Time and O(1) Space. We'll call that digit Y. Examples: Input : N = 100, S = 4 Output : 5 Upto 100 only 5 numbers(4, 13, 22, 31, 40) can produce 4 as their sum of digits. In this tutorial, we are going to write a program that finds the number less than N with digit sum greater than the digit sum of n. Do the same for 4th and 5th number. x = 6 Sum = 0 #Find the four digit number for i in range (999, 10000): #Find the sum of those numbers Sum = sum(map(int, str(i))) #Check if sum is = to x if Sum == x: num = i #Get rid of any identical numbers result = list(set(map(int, str 💡 Problem Formulation: The challenge is to write a Python program that finds the smallest number greater than n which has the exact same number of 1 bits in its binary representation. Find the smallest integer that is greater than M and whose digits add up to N. If there is no such subarray, return 0 instead. Examples: Input: N = 3, S Minimum Size Subarray Sum - Given an array of positive integers nums and a positive integer target, return the minimal length of a subarray whose sum is greater than or equal to target. Here's a brief explanation of the code: The function smallest_subarray_with_sum(arr, target_sum) takes two arguments: arr, which is the input array, and target_sum, the desired sum. and so on And I want to find the smallest number greater than (lets say) 4. So far I've got $n^2 = 1000k + n Given integer N and integer S, the task is to find the smallest number greater than or equal to N such that the sum of its digits does not exceed S. Starting with the least N significant digits. As an example, 60 2 = 3600 = 48 × 75, so both 48 and 75 are divisors of a power of 60. Find the smallest number with the given sum of digits and the sum of the square of digits. The task is to find the smallest and largest palindromic number possible with N digits. Examples: Explanation: Sum of digits of 10 is 1, which is less than 2. Suppose we have to form the greatest number with the digits 6, 5, 2, 9. For example for n = 7, the output is 17. If no such number can be formed then print “Not Possible”. , the 4 th number is 55. Now search the right side of above found digit ‘d’ for the smallest digit greater than ‘d’. Explanation: Sum of digits of 20 is 2, which is less than 3. Required number. The task is to find the smallest number that has length M (number of digits) and sum of digits as N. Given two integers N and K (K<N), the task is to find the smallest number greater than K by removing digits from N. Approach: The problem can be Problem: We are given a number N and we have to find the smallest possible palindrome greater than N that can be formed by using the same set of digits as in N. We can have other To solve consecutive integer problems, you need to:. Thus number of ways is = 9 × 9 × . We use cookies to ensure you have the best browsing experience on our website. . To find the next smallest number: Let 'next' be the next smallest number to ‘n’ having the same count of ‘1’ bits as ‘n’. Some examples: For M=3 and N=5, the smallest number is 104. Auxiliary Space: O(log 10 n) because of function call stack. Time complexity of this solution is O(n). Initially, the smallest number you can't make is 1. Examples: Input: N = 11 Output: 29 Explanation: The sum of the digits = 2 + 9 = 11 ( = N). Here's how it works. . Then, going from left to right, do the following: If the current number is bigger than the smallest number you can't make so far, then you know the smallest number you can't make - it's Given a number N as string, find the smallest number that has same set of digits as N and is greater than N. Given two integers N and K (K<N), the task is to find the smallest number greater than K by removing digits We are a given number n 1<=n<= 10^18, and we have to find minimal number that's greater than n and also it's adjacent digits are different, for example for 1000, answer is 1010, for 99, answer is 101. Therefore you should use a HashSet, which requires O(N) time to add N elements. Examples: Input: n = 111, m = 2, k = 2 Output: 122 Input: n = 111, m = 2, k = 3 Output: 222 Approach: Start iterating from n + 1 and for each integer i check whether it consists of digit m exactly k times. Employers: discover CodinGame for tech hiring. The K th number i. Their product is 1 × 2 = 2, which is greater than N. Input: N = 46 Output:-1 Approach: The idea is based on the following observations: If N < 10: Required The task is to find the smallest number such that the sum of its digits is s and the number of digits in the number are d. In fact 120 is the smallest number having 16 divisors. 1. ; The min_length variable is initialized to positive infinity to store the length of the smallest subarray found. Example. The task is to find two distinct prime numbers whose product will be equal to the given number. Examples: Input: N = 7182, K = 11 Output: 12 Explanation: Among all the possible combination, 12 is minimum number greater than 11. N = 189 -> smallest number = 100. Let’s take an example to understand the problem,InputN = 92534Output92543Solution ApproachA simple solu Note that the question has changed: There is an answer for the trivial question "Find the smallest multiple of N which has the same digit sum as N". What does this function do? It finds the smallest prime greater than n. Then, my method should return 353 as 353 is the smallest number greater than 320. x if you allow any integers;; 2x if you want only even integers; or; In the first traversal find the minimum element. How it can be implemented so that it calculates quickly for 10^18 Given a positive integer n, find the smallest integer which has exactly the same digits existing in the integer n and is greater in value than n. The smallest number is a power of 10, where the exponent is: (number of digits of the given N – 1) If we want to The task is to find the next prime number i. Examples: Input: N = "218765"Output: "251678"Explanation: The next number greater than 218765 with same Find the smallest number that is larger than a given number - earlier Excel versions The greater than sign > is a logical operator that lets you check if a number is larger than another number. Print -1 if no such Up front: It should be noted that processors capable of doing sqrt as a machine instruction will be fast enough. No doubt, its (micro)program uses Newton-Raphson, and this algorithm is of quadratic convergence, doubling the number of accurate digits with each iteration. N starts with 2. but the end goal of this question is almost the same as this other one which was asked just 4 months before this one, where it wouldn't have taken much adjustment to learn Given the sum of digits a and sum of the square of digits b . Examples: Input: n = 3, m = 1 Output: 3 Explanation: Three different ways to get sum n such that each term is greater than or equal to m are 1 + 1 + 1, 1 + 2 and 3 Input: n = 2, m = 1 Output: 2 I have a list of numbers (floats) 1. To maintain the sum of the digits, we decrement a non-null digit on a less significant position. (INDIRECT("1:"&TopN))))- at least two digits greater than $1$ (otherwise the sum now exceeds the product); exactly two digits greater than $1$ (the product of three such digits would exceed their sum by at least $2$). Note that this works correctly only for distinct element. Input: arr[] = {-8, -8, -3, 8}, K = 5 Output: 2 Naive Approach: The simplest approach to solve the problem is to Regular numbers are numbers that evenly divide powers of 60. If N is the greatest possible number with its set of digits, then print "Not Possible". The problem is to find the smallest number k such that the product of digits of k is equal to n. It means that we can count the number of such L and R that L < R and prefixSum[R] - prefixSum[L] >= K, which means prefixSum[L] <= prefixSum[R] - K. Print -1 if no such number exists or if the number of digits is more than 100. I just had the same question. This makes the number smaller. To count all n-digit numbers whose sum of digits equals a given target, we iterate through each number within the range of n-digit numbers. Find the smallest number larger than digit-x to the right of digit-x, and place it immediately left of digit-x. If k is less than sum of mid indices of a and b: If mid element of a is greater than mid element of b, we can safely ignore second half of a. For example, if N=10, Q=25. Examples: Input: N = "218765"Output: "251678"Explanation: The next number greater than 218765 with same Question: Given a number n, the task is to find two consecutive prime such that the product of these two prime is greater than or equal to n. Suppose that sum of digits is 9 then it should be 9 instead of 18,36,63 and similarly if sum of digits is 11 then desired answer is 29 not 92 or any other number bigger than 29. This question doesn't really need another answer, but there is a solution that has not been proposed yet, that I believe to be faster than what's been presented so far. The idea is to take the input number as a string and then iterate over all the characters (digits) to find the sum of digits. For a given number N(0<N<=100) find out the minimum positive integer X divisible by N, where the sum of digits of X is equal to N, and X is not equal to N. I tried to write sum of all numbers upto 53 and got this but i am not able to come up with a general formula. For example, if n is 5 (binary 101), the next higher number with two set bits is 6 (binary 110). Swap X and Y. Let's refer to the left-digit by "digit-x". on your code, the first smallest_greater should work if you switch the > with <= in if seq[i] > value:. 'next' can be greater than ‘n’ only if the flipped 0 bit was left to the 1 bit. To use as test case, take the following numbers: First find the kth smallest element of the array (using pivot partition method for finding kth order statistic) and then simply iterate through the loop to check which elements are less than the kth smallest element. Given a non-negative number n. Then find the largest digit that is to the right of X, and is smaller than X. Below is the illustration with the help of steps: If the first element of the array is not 0, then the smallest missing number is 0. This technique executes specific bit Given an array arr[] consisting of N integers, the task is to find the length of the Smallest subarray with a sum equal to K. Find count of N-digits If mid element of a is greater than mid element of b, we can ignore the first half of b, adjust k. Time Complexity: O(Log n) Auxiliary Space : O(Log n) Another Method: The idea is to use Recursive Binary Search to find the smallest missing number. Let this element be x. com; Home; About; Mobile; Advertise; Subjects; If the So, finally we can say that if a number k satisfies the difference condition then (k + 1) will also satisfy same equation so our job is to find the smallest number which satisfies the difference condition then all numbers greater than this and up to N will satisfy the condition so our answer will be N – smallest number we found. Optimal strategy is transforming many numbers to one number, like 2*2*2->8 and if there exist many variants to transform choose those one which gives the smallest number. Since 1 is the smallest positive integer that can divide the array elements, and any divisor greater than or equal to the maximum element will result in a quotient of 1 only (after rounding off to Given a set of digits S and an integer N, the task is to find the smallest positive integer if exists which contains only the digits from S and is a multiple of N. Method 1: Bit Manipulation Method. The binary weight of a positive integer is the number of 1's in its binary representation. Case 1: n < 10 When n is smaller than 10, the output is always n+10. For 534976, the right side of 4 contains 976. Examples: Input: N = "218765"Output Given an array containing digits between 0-9 and a number K, find the smallest number built by the digits in the array, such that it is larger than K For example, if array = [0,1] and K = 21, the The task is to find the greatest number that has same set of digits as N and is smaller than N. The idea is to start searching from 9 so that the number of digits in the result is minimized. kcikl efrhm pfhid mqfhvi jgc lbwivyv rplr xdsv zegfcxy aenzuvr

Find the smallest number greater than n with the same digit sum as n. We'll call that digit Y.
