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. WebSep 7, 2024 · Perform DFS at Root. Using DFS calculate the subtree size connected to the edges. The frequency of each edge connected to subtree is (subtree size) * (N – subtree size). Store the value calculated above for each node in a HashMap. Finally, after complete the traversal of the tree, traverse the HashMap to print the result.
