QUESTION:
Perform depth-first search on each of the following graphs; whenever there's a choice of vertices, pick the one that is alphabetically first. Classify each edge as a tree edge, forward edge, backedge, or cross edge, and give the pre and post number of each vertex
Step 1 of 3
1. Tree Edge: It's an edge that appears in the tree created by applying DFS to the graph.
2. Forward Edge: It's an edge (u, v) where v is a descendant but not a member of the DFS tree.
3. Back Edge: It is an edge (u, v) such that v is ancestor of node u but not part of DFS tree.
4. Cross Edge: It's an edge that connects two nodes without establishing an ancestor-descendant link between them.
