WebAug 10, 2024 · Approach: DFS is a traversal technique which involves the idea of recursion and backtracking. DFS goes in-depth, i.e., traverses all nodes by going ahead, and when there are no further nodes to traverse in the current path, then it backtracks on the same path and traverses other unvisited nodes. In DFS, we start with a node ‘v’, mark it as ... WebMar 26, 2024 · DFS Algorithm. Step 1: Insert the root node or starting node of a tree or a graph in the stack. Step 2: Pop the top item from the stack and add it to the visited list. Step 3: Find all the adjacent nodes of the node marked visited and add the ones that are not yet visited, to the stack. Step 4: Repeat steps 2 and 3 until the stack is empty. tryy
