Question

Can you use Python programming language to to this question?

Thanks

In a game of Go two players take turns to place black and white stones on a game board.
The winner is the player who manages to encircle a bigger area on the board with their
own game pieces.
Please write a function named who_won (game_board: list), which takes a two-
dimensional array as its argument. The array consists of integer values, which represent
the following situations:
• 0: empty square
• 1: player 1 game piece
• 2: player 2 game piece
