WebThe Subset sum problem asks: "given a set (or multiset) of integers, is there a non-empty subset whose sum is zero?". Now it has been proved that this is an NP complete problem and the only solutions for this problem are exponential. WebThe program should take two inputs: a. list of positive integers and a target sum. The program should output the total number of subsets that satisfy the given condition. For example, if the input list is [1, T, 8], and the target sum is 8, the program should output 2, because there are two subsets of the input list whose elements add up to 3: [1, T] and [8].

WebGiven a set of positive integers, check if it can be divided into two subsets with equal sum. For example, Consider S = {3, 1, 1, 2, 2, 1} We can partition S into two partitions, each having a sum of 5. S 1 = {1, 1, 1, 2} S 2 = {2, 3} Note that this solution is not unique. Here’s another solution. S 1 = {3, 1, 1} S 2 = {2, 2, 1}
