```cpp
#include <bits/stdc++.h>
int ix, iy, ia, ib;
long long int x, y, a, b;
int main()
{
scanf("%lld%lld", &x, &y);
scanf("%lld%lld", &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){
printf("long long int\n");
}
else{
printf("int\n");
}
return 0;
}
