@[xiaoshumiao](/user/1008513) 什么意思？

@[LZH2011](/user/696434) 不是，int 的下界是 $-2147483648$ 不是 $-2147483647$。
我怎么感觉你的 abs 做法不太对啊，要不你参考一下我的：
```cpp
#include<cstdio>
using namespace std;
int main() {
long long x1,y1,x2,y2;
scanf("%lld %lld %lld %lld",&x1,&x2,&y1,&y2);
if(x1*y1>2147483647||
x1*y2>2147483647||
x2*y1>2147483647||
x2*y2>2147483647||
x1*y1<-2147483648||
x1*y2<-2147483648||
x2*y1<-2147483648||
x2*y2<-2147483648)
printf("long long ");
printf("int");
return 0;
}
```
