WebJul 10, 2013 · Here is a nice proof of how you can reduce 3-SAT to the subset sum problem. As a consequence of the proof, the subset sum problem is NP-complete. … 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. But the order of elements should remain same as in the input array. Note : The order of subsets are not important. Input format : Line 1 : Integer n, Size of input array
