import java.util.Scanner;

public class Main {

    public static void main(String[] args) {
        
        Scanner sc=new Scanner(System.in);
        
        int n=Integer.parseInt(sc.nextLine());
        
        while(n-->0){
            
            String s=sc.nextLine();
            
            int round=0;
            for(int i=0;i<s.length();i++){
                char c=s.charAt(i);
                if(c>='a' && c<='z') round=(round+1)%26;
            }
            
            if(round==0){
                System.out.println("z");
            }else{
                System.out.println(String.format("%c",'a'+round-1));
            }
