```cpp
#include <bits/stdc++.h>
using namespace std;
long long a,b,c,d;
signed main() {
cin>>a>>b>>c>>d;
if(a * c < -2147483648 || a * c > 2147483647 || b * d < -2147483648 || b * d > 2147483647 ||a * d < -2147483648 ||a * d > 2147483647 || b * c < -2147483648 || b * c > 2147483647) {
cout<<"long long int";
}
else {

@[quxiangyu](/user/1241537) 能解释一下吗？

@[sly0801](/user/1086667) 如果其中两个数相乘大于了int的范围，那么输出"long long int" ，如果小于，那么输出"int";

@[quxiangyu](/user/1241537) 为什么cin的是4个数？
by sly0801 @ 2024-02-25 14:50:55
两对ab

@[sly0801](/user/1086667) 前两个数是x的取值范围，后两个数是y的取值范围

@[sly0801](/user/1086667) 如果任意两数相乘结果大于int的范围，那么输出"long long int" ，否则输出"int"
