@[wenzhuoren](/user/916276) 我看不懂你代码，但我建议你用整形溢出做这道题

```cpp
#include<bits/stdc++.h>
using namespace std;
int ix, iy;
int ia, ib;
long long x, y;
long long 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;
}
```
