Q2. Show the execution trace of DFS on the following directed graph. You must show discovery time v.d, finish time v.f, and the v.color for each node as the algorithm progresses. Indicate all tree edges, back edges, forward edges, and cross edges when the final DFS forest is constructed. Assume that the edges going out from a vertex are processed in alphabetical order and that each adjacency list is ordered alphabetically.

PI) Given undirected graph answer the following questions: (30 points) (a) Show how a Breath-First Search (BFS) works. Your starting node is B. You also need to show the discovery time for each node. (b) Given above graph, Apply Depth-First-Search (DFS), starting from node A. You should show the discovery time and return time (finishing time) on each of the node

b. (Weight: 15%) Perform DFS and BFS based on the following graph: - For BFS, provide the visit order. - For DFS, provide the finish order and label the special edges (if any) based on their type: back edge, forward edge, or cross edge. Sduro
