广度优先搜索 (BFS)算法也从树的根(或图的某个任意节点)开始,但与 DFS 不同的是,它首先探索邻居节点,然后再移动到下一级邻居。换句话说,BFS 按照与源顶点的距离顺序探索顶点,其中距离是从源顶点到节点的路径的最小长度。 二叉树中的BFS方法有层序遍历,逐层开始遍历。
voiddfs(MGraph G,intv) { inti; printf("%d ",v);//访问结点v vis[v] =true; for(inti = 0;i<G.n;i++)//访问与v相邻且未被访问过的结点 { if(G.edges[v][i]!=0&&vis[i]==false) { dfs(G,i); } } } voiddfs1(MGraph G,intv)//非递归实现(用到了栈,其实在递归的实现过程,...

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...
