#include<stdio.h>

    char a,b,c,d,e,f,g,h,i,j;

    l=k%11;
    if(l<10&&l==j-'0')
    printf("Right");
    else if(l == 10 && j == 'X')
    printf("Right");
    else if(l<10&&l!=j-'0')
    printf("%c-%c%c%c-%c%c%c%c%c-%d",a,b,c,d,e,f,g,h,i,l);
    else if(l==10&&l!=j-'0')
    printf("%c-%c%c%c-%c%c%c%c%c-X",a,b,c,d,e,f,g,h,i);
    return 0;
}

这样就能A了
