@[liyilin2011](/user/1028556) check函数没开long long，而且返回值写反了

@[lczcy1](/user/1087173) 还是不行呀
```cpp
#include <bits/stdc++.h>
#define INT_u 2147483647
#define INT_b -2147483648
using namespace std;
bool check(long long n){
if (n>INT_u || n<INT_b) return false;
return true;
}
int main(){
int i1,i2,j1,j2;
cin>>i1>>i2>>j1>>j2;
long long s1,s2,s3,s4;
s1=i1*j1;
s2=i1*j2;
s3=i2*j1;
s4=i2*j2;
if (check(s1) && check(s2) && check(s3) && check(s4)) cout<<"int";
else cout<<"long long int";
return 0;
}
```

@[liyilin2011](/user/1028556) check应该超int return true，不是false。而且应该是或（||)

@[lczcy1](/user/1087173) 我判断的是它是不是int呀
