Problem 7 (15 Points) Depth-First Search (a) What is the running

Problem 7 (15 Points) Depth-First Search (a) What is the running time of depth first search on a graph G=(V,E) ? (b) Complete the definition of a forward edge. (i) A tree edge is an edge in the depth first forest. (ii) A back edge is an edge (u,v) connecting a vertex u to an ancestor v in a depth first tree. (iii) A forward edge is an edge (u,v) (iv) Any other edge is called a cross edge. (c) Label the (start/finishing) times and the edges (tree w/ T, back w/ B, forward w/F, and cross w/C ) in the following graph. If several neighbors can be chosen, use the lexicographic smaller one first
