WebFeb 24, 2015 · In the constructor, Adj is allocated: Adj = new vector [V];. However, it is never deleted. You can do it in a destructor. The same is true for the visited array (you should delete it at the end of the DFS and BFS member-functions). Actually, there is a much easier way to deal with this issue: do not use pointers and dynamic memory ... WebMay 17, 2012 · You need to push on the front of the queue each unvisited element to implement a depth first search (just a little side note, not that it matters for determining connectivity). But you aren't incrementing z. z should be incremented up to z as well. Maybe another loop inside the for (int i) loop. – pippin1289. May 17, 2012 at 3:40.

Depth First Search in C++ Code with C

WebDepth-first search (DFS) is a straightforward graph traversal technique. The algorithm begins at a starting node, and proceeds to all other nodes that are reachable from the starting node using the edges of the graph.
