Question: The edge connectivity of an indirected graph is minimum number k of edges that must be removed to disconnect the graph. For example, the edge connectivity of a tree is 1, and the edge connectivity of a cyclic chain of vertices is 2. Demonstrate how the edge connectivity of an undirected graph G = (V, E) can be determined by running a maximum flow algorithm on at most |V| flow networks, each having O(V) vertices and O(E) edges.
