好吧……是时候补一下题解了

原题

题目大意

给出n只牛，k次排序，如果有一只牛一直比另外一只牛更前算作一对，输出一共有多少对。

题目分析

水题(数据规模小)，一开始初始化全部都可以，然后一个个删去就行(k和n反了……好险样例给的k和n不一样)

代码

#include<cstdio>
#include<cstring>bool map[25][25];
int line[25];
int main()
{int n,k,ans = 0;memset(map,1,sizeof(map));scanf("%d%d",&k,&n);for (int i = 0;i < k;i++){for (int j = 0;j < n;j++){scanf("%d",line + j);for (int kk = 0;kk <= j;kk++){map[line[kk]][line[j]] = false;}}}for (int i = 1;i <= n;++i)for (int j = 1;j <= n;++j){if (map[i][j]) ++ans;}printf("%d",ans);return 0;
}
