Tic-tac-toe

You’re going to create a game of Tic-tac-toe.

In Tic-tac-toe, players take turns placing either an X or an O onto a 3 by 3 grid.

The grid will be represented with the following coordinates.

In this game, the player will say the coordinate they want to play, and either an "X" or an "O" like so: This should return a new version of the board with that coordinate filled in.

board = [
  [nil, nil, nil],
  [nil, nil, nil],
  [nil, nil, nil]
]

move1 = TicTacToe.play(board, {0, 0}, "X")
[
  ["X", nil, nil],
  [nil, nil, nil],
  [nil, nil, nil]
]

TicTacToe.play(move1, {1, 1}, "O")
[
  ["X", nil, nil],
  [nil, "O", nil],
  [nil, nil, nil]
]

• BONUS: Ensure that the same player cannot play twice in a row.

• BONUS: Ensure that a player cannot play in an already filled spot.

• BONUS: Omit the "X" and "O" parameter and instead automatically figure out who’s turn it is. (X always plays first)

Enter your answer below.

defmodule TicTacToe do
  def play(board, coordinate, symbol) do
  end
end
