If we run DFS from a mother vertex, then all vertices will be reached.

It may seem that we can running DFS multiple times but note that each vertex is being processed only once, hence the time complexity will remain the same as in the case of a single DFS.

Let us go through the algorithm and pseudocode first to understand it better.

Algorithm :

Do the DFS traversal of the give graph and keep the track of last finished vertex 'v'.

Then check if v is the mother vertex of the given graph by doing DFS.

If v is not the mother vertex, then mother vertex does not exist for the given graph.
