Dfs traversal for directed graph

WebAug 5, 2024 · The Depth First Search (DFS) is a graph traversal algorithm. In this algorithm one starting vertex is given, and when an adjacent vertex is found, it moves to that adjacent vertex first and try to traverse in the same manner. It moves through the whole depth, as much as it can go, after that it backtracks to reach previous vertices to find new ... WebDepth-First Search (DFS) is a graph traversal algorithm that explores the vertices of a graph in depth before backtracking. It can be used to traverse both directed and undirected graphs and can be implemented using recursion or an explicit stack data structure.
