The idea is to create an empty multimap to store all subarrays’ ending index having a given sum. Traverse the array and maintain the sum of elements seen so far. If the sum is seen before, at least one subarray has zero-sum, which ends at the current index. shipping foam peanuts https://remaxplantation.com

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).
