/* floyd 传递闭包 开始Floyd 之后统计每个点能到的或能到这个点的 也就是他能和几个人确定胜负关系 第一批要有n-1个 然后每次减掉上一批的人数 麻烦的很 复杂度上天了.... 正难则反 我们考虑一定不能确定排名的 */ #include<iostream> #include<cstdio> #include<cstring> #define maxn 110 using namespace std; int n,m,f[maxn][maxn],ans; i…

题意: n个点,m条边. 若A 到 B的边存在,则证明 A 的排名一定在 B 前. 最后求所有点中,排名可以确定的点的个数. n <= 100, m <= 4500 刚开始还在想是不是拓扑排序. n这么小的数据范围,典型的传递闭包.直接可以用Floyd求. 求出传递闭包之后找哪些点与其他所有点都有直接关系,即所有的点和它之间排名都可以确定.计入答案. #include <iostream> #include <cstdlib> #include <cstdio&g…
