Your greedy approach will fail in many cases. In this case, your algorithm will choose (item 1) sum = 5, but the optimal answer should be (items 2 and 3), sum = 7. You need a dynamic programming approach to solve this and you can keep a matrix to store your previous states so that you can reconstruct the solution and get the …
