MAIN72 - Subset sum

You are given an array of N integers. Now you want to find the sum of all those integers which can be expressed as the sum of at least one subset of the given array.


First line contains T the number of test case. then T test cases follow, first line of each test case contains N (1 <= N <= 100) the number of integers, next line contains N integers, each of them is between 0 and 1000 (inclusive).  


For each test case print the answer in a new line.


0 1
2 3 2

AC in one go.
2.Traverse all the values from 1 to max_sum and add it to ans if any time it's possible.

AC in one go!! Simple recursive DP implementation of subset sum

If going for recursive solu treat dp as visited array ie 1 if visited and -1 if not .

Iterative - set/unordered set -> AC
Even if you like recursive solution try the iterative one and vice versa.

Unordered_set + Memoization + fast I/O : AC 0.06s
