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.
