WebJun 16, 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 tries 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 … WebApr 10, 2024 · DFS和BFS的使用场景对比. 1.DFS：深度优先遍历，在图或者树的遍历中会优先向深度进发（也就是会先遍历子节点），根据这一特点，可以联想到栈以及递归，两种实现（个人认为递归跟深度遍历更加关系密切一点）. 2.BFS：广度优先遍历，在图或者树的遍历 …
