Question: 17. You are given a directed graph G = (V, E) with weights ue on its edges e E E. The weights can be negative

17. You are given a directed graph G = (V, E) with weights ue on its edges e E E. The weights can be negative or positive. The Zero-Weight-Cycle Problem is to decide if there is a simple cycle in G so that the sum of the edge weights on this cycle is exactly 0. Prove that this problem is NP-complete
