(Manber - 7.3) The input is a connected undirected graph G = (V, E), a spanning tree T of G and a vertex v. Design a algorithm to determine whether T is a valid DFS tree of G rooted in v. In other words, determine whether T can be the output of DFS under some order of edges starting with v. The running-time of the algorithm should be O(| E | +| V |).
