WebThe problem is to check if there exists a subset X' of X whose elements sum to K and finds the subset if there's any. For example, if X = {5, 3, 11, 8, 2} and K = 16 then the answer is YES since the subset X' = {5, 11} has a sum of 16. Implement an algorithm for Subset Sum whose run time is at least O (nK). Notice complexity O (nK). WebGiven an array A of size n and an integer K, return all subsets of A which sum to K. Subsets are of length varying from 0 to n, that contain elements of the array.
