AC代码：

#include <stdio.h>  void judge (char c[13]);  int main()  {      int n;      char c[13];      scanf("%d",&n);      while (n--){          scanf("%s",c);          judge(c);      }      return 0;  }    void judge (char c[13])  {      int m;      m=(c[0]-'0'+2*(c[2]-'0')+3*(c[3]-'0')+4*(c[4]-'0')+5*(c[6]-'0')+6*(c[7]-'0')+7*(c[8]-'0')+8*(c[9]-'0')+9*(c[10]-'0'))%11;      if((m==10 && c[12]=='X') || m==(c[12]-'0'))          printf("Right\n");      else          printf("Wrong\n");  }
