You are playing a number guessing game called “Bulls and Cows” with a friend.
You write down a secret number, and your friend tries to guess it. After each guess, you provide a hint based on the following:
Bulls: The number of digits that are in the correct position in the guess.
Cows: The number of digits that are in both the secret and the guess but in different positions. (These are non-bull digits that could become bulls if rearranged.)
Your task is to return a hint for the guess, formatted as “xAyB”, where:
x is the number of bulls.
y is the number of cows.
Note: Both the
secretnumber and theguessmay contain duplicate digits.
Constraints:
secret.length, guess.length
