In this tutorial, we will learn how toimplement the BFS Traversal on a Graph, in the C++ programming language. What is BFS Traversal? As the name suggests, Breadth first search (DFS) algorithm starts with the starting node, and then traverse each branch of the graph until we all the node...

1. 定义 深度优先搜索 (DFS)算法从树的根部(或图的某个任意节点)开始,并在回溯之前沿着每个分支尽可能地探索。二叉树常见的DFS方法有前序遍历、中序遍历、后序遍历,本质上都属于深度优先搜索。 前序遍历:根结…
