import java.util.Scanner;

public class FizzBuzz {

    public static String fizzBuzz(String str) {
        if (str.length() > 0) {
            if (str.charAt(0) == 'f' && str.charAt(str.length() - 1) == 'b') {
                return "FizzBuzz";
            } else if (str.charAt(0) == 'f') {
                return "Fizz";
            } else if (str.charAt(str.length() - 1) == 'b') {
                return "Buzz";
            }
        }
        return str;
    }

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        System.out.print("Enter a string: ");
        String s = in.nextLine();
        System.out.println(fizzBuzz(s));
    }
