WebMay 7, 2013 · The adjacency list tells you which nodes you can get to in 1 hop from each node. In your example, node 0 can get to node 5, node 2, node 1, and node 6. I will just explain the case for BFS as once you get it you will likely have no problem with the case for DFS. Let graph be your adjacency list. bool visited [num_nodes]; // Array of booleans to ... WebIf DFS transversal doesn’t visit all vertices, then returning fake. Reverse all arcs (or find transpose or reverse of graph) Mark all vertices as not-visited in converse graph. Do a DFS traversal of reversed graph starting from same vertex v (Same as step 2). If DFS traversal doesn’t visit all vertices, then return wrong. Otherwise return true.
