Question: A directed graph G = (V, E) is said to be semi connected if, for all pairs of vertices u, v V, we have

A directed graph G = (V, E) is said to be semi connected if, for all pairs of vertices u, v ¬⁪ V, we have u →v or v→ u. Give an efficient algorithm to determine whether or not G is semi connected. Prove that your algorithm is correct, and analyze its running time.
