WebJul 17, 2015 · You could of course just insert the new node at the beginning of the list instead of appending it since the order of edges in the adjacency list doesnt matter. In C++ it would be: void insert (int x, int y) { node *xnode = new node; xnode->vertex = v; xnode->next = adj [x]; // either its null or is pointing to a node already adj [x] = xnode ...

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.
