import java.util.Scanner;
import java.io.FileInputStream;

class Solution{
    public static void main(String args[]) throws Exception{
     Scanner kb=new Scanner(System.in);
        int n=kb.nextInt();
        String[] arr=new String[n];
        for(int i=0; i<arr.length; i++){
            arr[i]=kb.next();
        }
 
        int[] answer=new int[n];
        int cnt=0;
        String s="abcdefghijklmnopqrstuvwxyz";

            cnt=0;
            for(int j=0; j<arr[i].length(); j++){
                if(arr[i].charAt(j)==s.charAt(j))
                    cnt++;
                else
                    break;

            System.out.println("#"+(i+1)+" "+answer[i]);
        }
