给定一个有N个顶点和E条边的无向图,请用DFS和BFS分别列出其所有的连通集.假设顶点从0到N−1编号.进行搜索时,假设我们总是从编号最小的顶点出发,按编号递增的顺序访问邻接点. 输入格式: 输入第1行给出2个整数N[1,10]和E,分别是图的顶点数和边数.随后E行,每行给出一条边的两个端点.每行中的数字之间用1空格分隔. 输出格式: 按照"{ v1 v2- vk}"的格式,每行输出一个连通集.先输出DFS的结果,再输出BFS的结果. 思路 很基础的DFS,BFS,也是理解的一种方式吧…

bfs,即广度优先搜索,主要通过队列(queue)进行操作. 稍微解释一下,队列是一种基础数据结构,其形态类似于一支长长的队伍,大概如下: 在C++中,队列的头文件定义为:#include<queue> 队列的声明:queue<T1> q; 这样就定义了一个数据类型为"T1"的队列q. 成员函数及作用集合: q.empty() 判断队列q是否为空,当队列q空时,返回true;否则为false(值为0(false)/1(true)). q.size() 访问队列q…

BFS基础 广度优先搜索(Breadth First Search)用于按离始节点距离.由近到远渐次访问图的节点,可视化BFS 通常使用队列(queue)结构模拟BFS过程,关于queue见:算法与数据结构基础 - 队列(Queue) 最直观的BFS应用是图和树的遍历,其中图常用邻接表或矩阵表示,例如 LeetCode题目 690. Employee Importance: // LeetCode 690. Employee Importance/* class Employee { publi…
