水题模拟 建一个图,每两个牛进行比赛就连一条边,然后两遍dfs求出比他弱和比他强的牛,最后如果相加数量等于n,说明他能与全部的牛进行比较,排名确定. #include<bits/stdc++.h> using namespace std; ][],mp2[][]; int n,m,ans; ],f2[]; ]; void dfs1(int x){ f1[x]++;vis[x]=; ;i<=n;i++){ if(!mp1[x][i]||vis[i])continue; dfs1(i); }…

P2419 [USACO08JAN]牛大赛Cow Contest Floyd不仅可以算最短路,还可以处理点之间的关系. 跑一遍Floyd,处理出每个点之间是否有直接或间接的关系. 如果某个点和其他$n-1$个点都有关系,那么它的排名就是可确定的. #include<iostream> #include<cstdio> #include<cstring> #define re register using namespace std; ][],ans; int main(…

题目描述 FJ的N(1 <= N <= 100)头奶牛们最近参加了场程序设计竞赛:).在赛场上,奶牛们按1..N依次编号.每头奶牛的编程能力不尽相同,并且没有哪两头奶牛的水平不相上下,也就是说,奶牛们的编程能力有明确的排名. 整个比赛被分成了若干轮,每一轮是两头指定编号的奶牛的对决.如果编号为A的奶牛的编程能力强于编号为B的奶牛(1 <= A <= N; 1 <= B <= N; A != B) ,那么她们的对决中,编号为A的奶牛总是能胜出. FJ想知道奶牛们编程能力的…
