提交错误记录 代码：

#include<bits/stdc++.h>
#define ll long long
using namespace std;

int main() {
	ll x1, y1, x2, y2;
	cin >> x1 >> x2 >> y1 >> y2;
	ll high = x2 * y2, low = x1 * y1;
	if (high > 2147483647 || low < -2147483648) cout << "long long int";
	else cout << "int";
	return 0;
}

#2-#9和#101错了

求解，为什么错了
