Hi, could someone please explain step by step how to solve this, and solve similar questions to this. Thanks!

Take a directed graph G = (V, A) with arc capacity Wa for each arc a E A. Let S+(S*) be a minimum capacity s t cut in a graph G = (V, A). Prove that if (i, j) ES+(S*) then there is no minimum capacity s - t cut S+(S) such that j E and i EV | . Take a directed graph G = (V, A) with arc capacity Wa for each arc a E A.
