Given a graph G = (V, E), a vertex v is

Given a graph G = (V, E), a vertex v is called sink if there are no outgoing edges from v. A vertex v is called super sink if v is a sink and for every vertex u elementof V, there is an edge from u to v. Prove that every DAG (Directed Acyclic Graph) has a sink. Suppose you are given a graph G = (V, E) in adjacency matrix representation. Give an algorithm to compute super sink, if exists. Derive the time bound of your algorithm. Your grade depends the run time of your algorithm. Given a graph G = (V, E), a vertex v is called sink if there are no outgoing edges from v.
