Consider the following problem: Defnition :Twographs are isomorphicif there existsapermulation suchthat if the nodes of one of the graphs are renamed according to thispermutation, the resultant graph is the same as the second graph. Problem: Giventwo graphs G1 =(V1,E1) and G2 =(V2,E2) together with 0 2| k, an integer k. You are required to determine if there exist a subgraph 0 G 1 = (V1,E and G 0 0 0 0 1) of G1, and a subgraph G2 =(V2,E2) of G2, suchthat |E1| 2 are isomorphic. Is thisproblem in P? Ifyes, give anpolynomial time algorithm. Is thisproblem NP-complete? Ifyes, proveyour claim.
