It takes input from the user in the form of the number of vertices and edges in the graph, and the edges themselves. It creates an adjacency list to store the edges of the graph, and then uses DFS to traverse the graph and check if all vertices are visited.

Depth First Search Tutorials & Notes Algorithms

WebWe can easily find the root vertex in O (n + m) time using a DFS. The idea is to start a DFS procedure from any node of the graph and mark the visited vertices. If there are any unvisited vertices, start the DFS again until all vertices are visited. Finally, the vertex having the maximum departure time in DFS is a candidate for the root vertex.
