Please write it in detail.

Suppose that G = (V, E) is a directed graph with |V| = n and JE| = m unless
otherwise stated. Also suppose that all edge capacities are integral and that there are no
directed 2-cycles.
Then consider the following network (G, u, s, t) with edge capacities given by the labels

(a) Run the Ford-Fulkerson algorithm to find a maximum flow ƒ* . Be sure to give the flow
f and corresponding residual graph G, after each iteration.
(b) Define S := {v€ V | there exists an s – v path in G; } . What is S, and what is the value
u(6* (S)) of the cut?
