Explanation
- **Zobrist Hashing** is a hashing technique used in computer games (like chess) to represent game states efficiently. It works by assigning a random bitstring to each possible move or position, then XORing the bitstrings together to create a unique hash for the current game state.

Steps
- Assign a random bitstring to each possible position or move.
- For each move, XOR the corresponding bitstrings together to update the hash.
- The resulting hash represents the current game state.

Time Complexity
- O(1) for each update or calculation, as XOR operations are constant-time.
