Question: Given a directed graph G = (V, E), let G2 = (V 0 , E0 ) be defined as follows: V 0 = V ;

Given a directed graph G = (V, E), let G2 = (V 0 , E0 ) be defined as follows: V 0 = V ; hu, vi E0 if there is a path of length 2 between u and v in G. Suppose that a directed graph G is given as adjacency list. Give an algorithm to compute G2 . Derive the time bound of your algorithm. Your grade depend on the run-time. Here m is number of edges in G and n is number of vertices in G.
