AC代码求关


#include <bits/stdc++.h>
using namespace std;
int main()
{
    string a;
    cin >> a;
    int len=a.size(),cnt=1,sum=0;
    for(int i=0;i<=10;i++)
    {
        if(a[i]>=48 && a[i]<=57)
        {
            int k=a[i]-48;
            sum+=k*cnt;
            cnt++;
        }
    }
    sum%=11;
    char c;
    if(sum==10)
    {
        c='X';
    }
    else
    {
        c=sum+48;
    }
    if(c==a[12])
    {
        cout << "Right";
    }
    else
    {
        a[12]=c;
        cout << a;
    }
    return 0;
}
