A smaller sudoku game

NumPy data types, which emphasize speed, are more specific than Python data types, which emphasize flexibility. When working with large amounts of data in NumPy, it's good practice to check the data type and consider whether a smaller data type is large enough for your data, since smaller data types use less memory.

It's time to make your sudoku game more memory-efficient using your knowledge of data types! sudoku_game has been loaded for you as a NumPy array. numpy is imported as np.
