WebOur first attempt. Putting those ideas together, we arrive at the following sketch of a depth-first traversal algorithm for a graph. DFT (Graph g): let startVertex be any vertex in g DFTr (g, startVertex) DFTr (Graph g, Vertex v): visit (v) for each vertex w such that the edge v → w exists: DFTr (g, w) DFT is the complete algorithm; it's job ...
