题目-计算是周几

#include<bits/stdc++.h>
using namespace std;
int main() {
    int a, b, c=1;
    cin >> a >> b;
    for (int i = 1; i <= b; i++) {
        c *= a;
        c %= 7;
    }
    if (c == 0) {
        cout << "Sunday";
    }
    else if (c == 1) {
        cout << "Monday";
    }
    else if (c == 2) {
        cout << "Tuesday";
    }
    else if (c == 3) {
        cout << "Wednesday";
    }
    else if (c == 4) {
        cout << "Thursday";
    }
    else if (c == 5) {
        cout << "Friday";
    }
    else if (c == 6) {
        cout << "Saturday";
    }
    return 0;
}
