Pop a node from stack to select the next node to visit and push all its adjacent nodes into a stack. Pick a starting node and push all its adjacent nodes into a stack. This recursive nature of DFS can be implemented using stacks. All the nodes will be visited on the current path till all the unvisited nodes have been traversed after which the next path will be selected. Here, the word backtrack means that when you are moving forward and there are no more nodes along the current path, you move backwards on the same path to find nodes to traverse. It involves exhaustive searches of all the nodes by going ahead, if possible, else by backtracking. ![]() The DFS algorithm is a recursive algorithm that uses the idea of backtracking.
