"""
Simulates a Proof of Work mining process.
The miner must find a nonce such that the hash of the nonce starts
with a specific number of leading zeros (difficulty)
with a specific number of leading zeros (difficulty).
Args:
difficulty (int): The number of leading zeros required in the hash.
difficulty (int): The number of leading zeros required in the hash.
Returns:
int: The nonce value that solves the puzzle.
int: The nonce value that solves the puzzle.
Example:
>>> result = proof_of_work(2) # Difficulty of 2 should be fast
>>> isinstance(result, int)
True
>>> result = proof_of_work(2) # Difficulty of 2 should be fast
>>> isinstance(result, int)
True
