我是个老六

上代码，（懒得说了）。
今日图片：

#include<bits/stdc++.h>
using namespace std;
int n;
int main(){
	cin>>n;
	n++;
	while(n>7){
		n-=7;
	}
	switch(n){
		case 1:cout<<"monday";break;
		case 2:cout<<"tuesday";break;
		case 3:cout<<"wednesday";break;
		case 5:cout<<"friday";break;
		case 4:cout<<"thursday";break;
		case 6:cout<<"saturday";break;
		case 7:cout<<"sunday";break;
	}
	return 0;
}
