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. WebFeb 22, 2024 · If there is a cycle in the graph, then it is not possible to finish all tasks (because in that case there is no any topological order of tasks). Both BFS and DFS can be used to solve it. Since pair is inconvenient for the implementation of graph algorithms, we first transform it to a graph.

"WebAug 24, 2024 · Two very famous methods of traversing the graph/tree are Breadth-first-search (BFS) and Depth-first-search (DFS) algorithms. The main difference between these two methods is the way of exploring nodes during our traversal- BFS: Tries to explore all the neighbors it can reach from the current node. It will use a queue data structure. " - Gfg dfs practice
