Approach: This approach is based on the concept of Power-set. Minimum jumps to reach the end. Thanks for contributing an answer to Stack Overflow! Coin Change. For every index i in the array, call the recursion function to find out all the possible subsets with elements in the range [i, N-1] having sum K. Every time a subset with sum K is found, check if its size is greater than the current max_length value. It's probably more of the code review question, rather than stack overflow: @Norbert About the input, if I read the input first, then I'll have to pass through the array two times, right? This is the first version of the subset. Then I selected the first one checked if its greater than S. If not, I selected the second element also, and so on until the sum becomes greater than or equal to S. This algorithm works and I got many test cases correct. So I sorted the list of given integers largest first. The smallest subset with sum greater with all other elements is 2 Greedy Approach. Care to help me a bit? Initialize a global variable max_length to 0, which stores the maximum length subset. For every index i in the array, call the recursion function to find out all the possible subsets with elements in the range [i, N-1] having sum K. Every time a subset with sum K is found, check if its size is greater than the current max_length value. Given an array of integers, find the length of smallest subarray whose sum of elements is greater than the given positive number. If n is even, then sizes of two subsets must be strictly n/2 and if n is odd, then size of one subset must be (n-1)/2 and size of other subset must be (n+1)/2. Objective: Given an array (non-negative) and an integer, Find the Subarray whose sum is equal to the given integer. Take the first T numbers so that the sum of the T exceeds S, sort that. For example, for an array of numbers A= {7, 5, 6, 11, 3, 4} You have to find whether there exists a non-empty subset of A whose sum is greater than or equal to S. You have to print the size of minimal subset whose sum is greater than or equal to S. If there exists no such subset then print -1 instead. Follow the steps below to solve the problem: Below is the implementation of the above approach: edit Algorithm.
