Question: Given a flow network G = ( V , E ) and a flow f , we call f cyclic if there is some cycle

Given a flow network G =(V, E) and a flow f, we call f cyclic if there is some cycle C E
with f(e)>0 for all e in C. Design an efficient algorithm that, given a flow network G and flow
f, modifies f to be acyclic without changing its value. If your algorithm requires finding a cycle
in a directed graph, explain how you implement such a step
