WebDFS 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 DFS traversal of the tree. WebThe dfs function iterates through all the nodes in the graph and for each unvisited node, it calls, the dfsVisit. Complexity. The time complexity of DFS is O(V + E) where V is the number of vertices and E is the number of edges. This is because the algorithm explores each vertex and edge exactly once.
