解题思路:

注意事项:

参考代码:

import java.util.*;

public class Main{

public static void main(String args[]){

    char a[] = new char[14];

    char mod[] = {'0','1','2',3,'4','5','6','7','8','9','X'};

    a = new Scanner(System.in).next().toCharArray();

    int i,x = 1,t = 0;

    for(i = 0;i < 12;i++)

    if(a[i] != '-')t += (a[i] - '0') * x++;

    if(mod[t % 11] == a[12])System.out.print("Right");

else

{

      a[12] = mod[t % 11];

  System.out.print(a);

    }

  }

}
