@wuliu21

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

int cnt;

int main()
{
    string t;
    cin >> t;
    string s;
    s[0] = t[0],s[1] = t[2],s[2] = t[3],s[3] = t[4],s[4] = t[6],s[5] = t[7],s[6] = t[8],s[7] = t[9],s[8] = t[10];
    int a[10];
    for (int i = 0;i < 9;i++)
        a[i + 1] = s[i] - '0';
    for (int i = 1;i <= 9;i++)
        cnt += a[i] * i;
    if (cnt % 11 != 10 && cnt % 11 == t[12] - '0' || t[12] == 'X' && cnt % 11 == 10)
        cout << "Right" << endl;
    else
    {
        for (int i = 0;i < 12;i++)
            cout << t[i];
        if (cnt % 11 != 10)
            cout << cnt % 11 << endl;
        else
            cout << 'X' << endl;
    }
    return 0;
}

我最开始也栽这俩测试点上了，改了接近两小时很长时间
