@[_O__o_](/user/741120) 万一全是负数怎么办？所以要正负都考虑```c
#include <bits/stdc++.h>
using namespace std;
int ix,iy,ia,ib;
long long x,y,a,b;
int main (){
cin >> x >> y >> a >> b;
ix=x,iy=y,ia=a,ib=b;
if (x*a!=ix*ia || x*b!=ix*ib || y*a!=iy*ia || y*b!=iy*ib)
cout << "long long int";
else cout << "int";
return 0;
}
```
最后:~~原来你也~~
