- 3. Given a Directed Acyclic Graph (DAG) G = (V,E), design an algorithm to determine whether there exists a path that can visit every node. The algorithm should have time complexity of O(|E|+ |V]). Prove why your algorithm is correct.arrow_forwardProve that there exists a maximum flow f in G, such that the set of edges carrying positive flowis acyclic. In other words, f has the property that for every directed cycle in G made up of edgese1, e2, . . . , ek, at least one of the values f (e1), f (e2), . . . , f (ek) is equal to zero.arrow_forwardHow can we merge parallel edges that are in the same direction in a flow network G?arrow_forward
