给你一组数据：
-1000000 -99999999 3 4
（纯属虚构）

@[CCA_zhujunwei](/user/1014750) **把 -2147483647 换成INT_MIN , 再加一组 xx*yx 的check**
------------
### 代码：
```cpp
#include<iostream>
#include<climits>
using namespace std;
#define ll long long
ll xx, xy, yx, yy;
int main(){
cin >> xx >> xy >> yx >> yy;
if(xy * yy > 2147483647 || xy * yy < INT_MIN
|| xx * yy > 2147483647 || xx * yy < INT_MIN
|| xy * yx > 2147483647 || xy * yx < INT_MIN
||xx * yx > 2147483647 || xx * yx < INT_MIN){
cout << "long long int";
}
else{
cout << "int";
}
return 0;
}
```
