题解

像这种题我们可以用switch来做，这用会更简洁

#include<iostream>
using namespace std;
int main(){
    int n,t;
	cin>>n;
	n=(n+1)%7;
	switch (n){
		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;
		case 0:cout<<"sunday";break;
	}
    return 0;
}
