代码

#include<bits/stdc++.h>
using namespace std;
int main()
{
    char s[14],c;
    cin>>s;
    int h=0,k=0;
    for(int i=0;i<11;i++)
    {
        if(s[i]!='-')
        {
            k++;
            h+=k*(s[i]-'0');
        }
    }
    h%=11;
    if(h==10) c='X';
    else c=h+'0';
    if(c==s[12]) cout<<"Right"<<endl;
    else
    {
        s[12]=c;
        cout<<s;
    }
    return 0;
}
