@[sixer_120201](/user/1102621) 你没有判断 ad 和 bc。

所有的既要判断是否 >INT_MAX，又要判断是否 <INT_MIN

```cpp
#include<bits/stdc++.h>
using namespace std;
typedef long long ll;
bool check(ll a, ll b)
{
return (a * b > INT_MAX) || (a * b < INT_MIN);
}
int main()
{
ll a,b,c,d;
cin>>a>>b>>c>>d;
cout<< ((!check(a, c) && !check(b, d) && !check(b, c) && !check(a, d))?"int":"long long int") <<endl;
return 0;
}
```
