Following are the pre and post timestamps of the vertices for the
DFS TRAVERSAL starting from B.
Note: the graph being disconnected ,vertices D,G and H can never be reached . Hence their post and pre timestamps are 0.
| Vertex | Pre | Post |
|---|---|---|
| A | 10 | 11 |
| B | 1 | 12 |
| C | 6 | 7 |
| D | 0 | 0 |
| E | 2 | 9 |
| F | 3 | 8 |
| G | 0 | 0 |
| H | 0 | 0 |
| I | 4 | 5 |

Execute DFS on the graph below, starting in node a. Whenever you have a choice which vertex to visit next, choose the next vertex in the adjacency list of the vertex (e.g., when you have reached node e, you must first try to visit node f, then g, and then . Indicate the outcome of the algorithm by labeling the edges of the graph either as T (tree edge) F (forward edge), B (back edge), or C (cross edge). Label...

Draw the DFS search tree with starting vertex E and break ties alphabetically. Assuming unit edge length (i.e., ignore edge weight), draw the BFS search tree with starting vertex E and break ties alphabetically. Suppose the Dijkstras algorithm is run on the graph with starting vertex E: (i) draw a table showing the intermediate distance values of all vertices at each iteration of the algorithm; (ii) show the final shortest-path tree.
