@[baixiaoxiao](/user/763945) j 是这样写的？
by Trinitrotoluene @ 2022-08-05 09:46:36
定义全局变量

``
for (int j = i; j <= m; j++) //j应从1开始
``
这里错了？

哦，不对。是输入时应该是从一到m

而且j从1开始

@[Trinitrotoluene](/user/141555) j改一下就好了<捂脸
by baixiaoxiao @ 2022-08-05 09:48:18
我改的：
```
#include<bits/stdc++.h>
int n, m, q[114514];
double total[114514];
using namespace std;
int main() {
cin >> n >> m;
for (int i = 1; i <= n; i++) {
for (int j = 1; j <= m; j++) {
cin >> q[j];
}
sort(q+1,q+1+m);
q[1] = 0;
q[m] = 0;
for (int k = 1; k < m; k++){
total[i] += q[k];
q[k] = 0;
}
total[i] /= (m-2);
}
sort(total+1,total+1+n);
printf("%.2lf", total[n]);
return 0;
}
```

好家伙，就改一下J 就行
```
for (int j = 1; j <= m; j++)
```
二维数组搞错了吧，都没输完整
