@[Gohldg](/user/757214) 啊！
你这写的是什么！？
`min_ans<-2147483648||max_ans>2147483647` 这不应该是 `long long int` 吗
然后你取 $\min$ 不应该是所有的取 $\min$ 吗
$\max$ 同理。
```cpp
#include <bits/stdc++.h>
using namespace std;
int main(){
long long x1,x2,y1y,y2y;//
cin>>x1>>x2>>y1y>>y2y;
long long ans1,ans2,min_ans,max_ans;
min_ans=min({x1*y1y,x1*y2y,x2*y1y,x2*y2y});
max_ans=max({x1*y1y,x1*y2y,x2*y1y,x2*y2y});
// cout<<min_ans<<' '<<max_ans<<endl;
if(min_ans<-2147483648ll||max_ans>2147483647ll){
cout <<"long long int";
}else cout <<"int";
return 0;
}
```

@[QWQ_123](/user/740328) 在改之前是对的，改之后反了awa

哦哦，懂了，抱歉，打扰了
by Gohldg @ 2024-02-15 21:28:43
@[Gohldg](/user/757214) 我不是给您发代码了吗（
by QWQ_123 @ 2024-02-15 21:28:46
@[Gohldg](/user/757214) 就是
```cpp
min_ans=min({x1*y1y,x1*y2y,x2*y1y,x2*y2y});
max_ans=max({x1*y1y,x1*y2y,x2*y1y,x2*y2y});

@[Gohldg](/user/757214) 首先，开long long,然后，最大值最小值搞错了，接着，判断写错了
```cpp
#include <iostream>
using namespace std;
int main(){
long long x1x,x2x,y1y,y2y;
cin>>x1x>>x2x>>y1y>>y2y;
long long min_ans=min(x1x*y1y,min(x1x*y2y,min(x2x*y2y,x2x*y1y)));
long long max_ans=max(x1x*y1y,max(x1x*y2y,max(x2x*y2y,x2x*y1y)));
if(min_ans<-2147483648||max_ans>2147483647){
cout <<"long long int";
}else cout <<"int";
return 0;
}
```
