        char ch = in.next().charAt(0);
        
        if (Character.isLetter(ch)) {
            ch = Character.toLowerCase(ch);
            for (char x = ch; x >= 'a'; x--) {
                System.out.println(x);
            }
        }
        else {
            System.out.println("Invalid input");
