  1. Print the following message:
    Bulls and Cows
    ==============
    This is an ancient game with guessing numbers.
  2. Draw 4-digit random number.
  3. Print the following message:
    A secret number of 4-digit has been draw!
  4. Obtain a 4-digit number or "quit" from user by prompting following message repeatly:
    Please enter a 4-digit number (or type 'quit' to exit):
  5. If the input is "quit" show the following message (replace 0000 with the actual number being drawed
    The secret number is: 0000
  6. Show the number of digit(s) that have correct position as bull and the number of digit(s) that appeared without exact position as cow. For instance: The random number is 1234 and the user input 1355. Exact position: "1", appeared without exact position: "3". The system should display the following message:
    1 bull 1 cow
  7. If no digit found n the random number, the following should be shown instead:
    Neither a bull nor a cow!
  8. On the other hand, if the user guess the 4 digits correctly, the system should show the following message instead:
    4 bulls! You are a genius!
  9. Ask the user to play again if 4 digits have been guessed correctly by showing the following message:
    Do you want to play a new game (Y/N)?
  10. Show the following message if user has chosen to quit the program:
    Thank you for playing Bulls and Cows!
