题目链接:http://acm.split.hdu.edu.cn/showproblem.php?pid=5876 题意:有一个含有n个点的无向图,已知图的补图含有m条边u, v:求在原图中,起点s到其他n-1个点的最短距离,默认边的距离为1: 由于点的个数较大,不能建原图,只能从补图入手:从起点s开始,与s不直接相连的点的最短距离是1,然后再从这些点开始搜,循环即可,用队列表示,队列空了就结束了: #include<stdio.h> #include<string.h> #inc…

In graph theory, the complement of a graph G is a graph H on the same vertices such that two distinct vertices of H are adjacent if and only if they are not adjacent in G. Now you are given an undirected graph G of N nodes and M bidirectional edges o…
