WebDepth First Search ( DFS ) Algorithm. DFS is an algorithm for traversing a Graph or a Tree. DFS starts with the root node and explores all the nodes along the depth of the selected path before backtracking to explore the next path. DFS makes use of Stack for storing the visited nodes of the graph / tree. Example: Consider the below step-by-step ... WebThe DFS algorithm works as follows: Start by putting any one of the graph's vertices on top of a stack. Take the top item of the stack and add it to the visited list.
