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.

WebA Depth–first search (DFS) is a way of traversing graphs closely related to the preorder traversal of a tree. Following is the recursive implementation of preorder traversal: procedure preorder (treeNode v) { visit (v); for each child u of v preorder (u); } To turn this into a graph traversal algorithm, replace “child” with “neighbor”.

Most Upside ... WebHow Does DFS Work? DFS starts traversing the graph from a starting node (provided as input to the algorithm). It chooses a path starting from this node, and goes as deep as it can. After exhausting that path, it backtracks until it finds another unexplored path and then explores it recursively.
