            if(h[sum%11]!=c){
                //System.out.println(s);
                ss[sum1++]=s;
                //System.out.println(ss[sum1-1]);
            }

        }
        if(sum1==0){
            System.out.println("All passed");
        }
        else{
            for(int i=0;i<sum1;i++){
                System.out.println(ss[i]);
            }
        }
    }
}

x可能是大写的,要对大写的X也判断

        if(s.charAt(j)=='x' || s.charAt(j)=='X'){  //x可能是大写的,要对大写的X也判断
        if(s.charAt(17)=='x' || s.charAt(17)=='X')  //x可能是大写的,要对大写的X也判断

import java.util.Scanner;
public class Main{
    public static void main(String[] args){
        Scanner sc=new Scanner(System.in);
        int a=sc.nextInt();
        int sum1=0;
        String[] ss=new String[a];
        int[] b={7,9,10,5,8,4,2,1,6,3,7,9,10,5,8,4,2};
        int[] h={1,0,10,9,8,7,6,5,4,3,2};
        for(int i=0;i<a;i++){
            String s=sc.next();
            int sum=0;
 
            for(int j=0;j<17;j++){
                if(s.charAt(j)=='x' || s.charAt(j)=='X'){  //x可能是大写的,要对大写的X也判断也

                    sum=sum+10*b[j];
                }
                else{
                    sum=sum+(s.charAt(j)-'0')*b[j];
                }
            }
            //System.out.println(sum);
            int c;
            if(s.charAt(17)=='x' || s.charAt(17)=='X')  //x可能是大写的,要对大写的X也判断也
                c=10;

        }
        if(sum1==0){
