简单

暴力纯输出，十分简单！！！

# include <iostream>//头文件
using namespace std;//主函数
int main(){//程序入口
    int a;//int整形a
    cin >> a;//输入a
    switch (a){
        case (1):
            cout << "Monday";break;
        case (2):
            cout << "Tuesday";break;
        case (3):
            cout << "Wednesday";break;
        case (4):
            cout << "Thursday";break;
        case (5):
            cout << "Friday";break;
        case (6):
            cout << "Saturday";break;
        default:
            cout << "Sunday";break;
    }
    return 0;
}
```cpp

#include<bits/stdc++.h>
using namespace std;
typedef long long apple;
apple a,b,c,d,sum=0;
int main(){
    cin>>a>>b>>c>>d;
    sum=d*1000;
    if(a*b*c<sum) cout<<"No";
    else cout<<"Yes";
    return 0;
}
