应该可以暴力吧。
code
```cpp
#include <bits/stdc++.h>
#define db double
#define rtn return
using namespace std;
long long a[6],b,c,d,n,m,nn,mm;
signed main() {
cin>>a[1]>>a[2]>>a[3]>>a[4];
for(int i=1;i<=2;i++){
for(int j=3;j<=4;j++){
int res=a[i]*a[j];
long long res2=a[i]*a[j];
if(res!=res2){
cout<<"long long int";
return 0;
}
}
}
cout<<"int";
return 0;
}
```
