第八行

@hz_Glmc 可以参考一下我的。

#include<bits/stdc++.h>
using namespace std;
int main(){
    string d[10]={"Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"};
    int n,m,a=1;
    cin>>n>>m;
    n%=7;
    for(int i=1;i<=m;i++) a*=n,a%=7;
    cout<<d[a];
    return 0;
}

求关。

直接暴力，7个if完事

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

signed main()
{
    int a,b,ans=1;
    cin>>a>>b;
    for(int i=1;i<=b;i++)
    {
        ans*=a;
        ans%=7;
    }
    int c=ans%7;
    if(c==0)cout<<"Sunday";
    if(c==1)cout<<"Monday";
    if(c==2)cout<<"Tuesday";
    if(c==3)cout<<"Wednesday";
    if(c==4)cout<<"Thursday";
    if(c==5)cout<<"Friday";
    if(c==6)cout<<"Saturday";
    return 0;
}
