Question: Let G = ( V , E ) be a flow network with source s , s i n k t , and integer capacities.

Let G=(V,E) be a flow network with source s,sinkt, and integer capacities. Suppose that
we are given a maximum flow in G.
(a) Suppose that the capacity of a single edge (u,v)inE is increased by 1. Give an
O(V+E)-time algorithm to update the maximum flow.
(b) Suppose that the capacity of a single edge (u,v)inE is decreased by 1. Give an
O(V+E)-time algorithm to update the maximum flow.
