Rules

One of the players comes up with a secret number, and the other player tries to guess it.

The secret number must consist of 4 digits and each digit must be unique.

For example:

• 1112 would not be an acceptable secret number
• 1234 on the other hand is an acceptable value for the secret number, since each digit is unique

After each guess, the player will get a hint to help them guess better next time around.

The hint tells the player how many bulls and how many cows there were. What are bulls and cows?

• If there are any matching digits and they are in their right positions, they are counted as "bulls".
• If in different positions, they are counted as "cows".

For example, with a secret number 4271:

Player's try: 1234

Hint: 1 bull and 2 cows

How did we arrive at one bull and two cows? The bull is the number 2 as it is in the right position.

The cows are 4 and 1, as they exist in the secret number but they are not in the right position.

Do not disclose to the user which digit is a cow and which one is bull, just how many there are (if any).

There is no limit on the number of guesses - guessing continues until the player figures out the other player's secret number.

Once the player has guessed the secret number correctly, display a message to congratulate them.
