25. Let G be a connected, undirected graph, and let V be the set of all vertices in G. Define a relation R on V as follows: for any vertices a, b e V, a Rb if there is a path from a to b with an even number of edges. (A path may use the same edge more than once.) Prove that R is an equivalence relation.
