@[qichuanyi](/user/1018548) `double v = a[n] / (m - 2) * 1.00;` 改为 `double v = a[n] / (m - 2.00);`

```cpp
int n,m,a[1001],maxn[1001] = {INT_MIN},minn[1001] = {INT_MAX};
```
你这个初始化方式有问题，这样初始化它只有第一个元素（`maxn[0]`）是 `INT_MIN`，其余的全是 $0$。另一个数组同理：
```cpp
#include<bits/stdc++.h>
using namespace std;
int n, m, a[1001], maxn[1001], minn[1001];
int main() {
cin >> n >> m;
memset(maxn, -0x3f, sizeof maxn);
memset(minn, 0x3f, sizeof minn);
for (int i = 1; i <= n; i++) {
for (int j = 1; j <= m; j++) {
int w;
cin >> w;
a[i] += w;
maxn[i] = max(maxn[i], w);
minn[i] = min(minn[i], w);
}
a[i] -= maxn[i] + minn[i];
}
sort(a + 1, a + 1 + n);
double v = (a[n] + 0.0) / (m - 2.0);
printf("%.2f", v);
return 0;
}
```
