A TICTACTOE GAME.
1. create a function to display board : display_board()
2. create a function to collect the marker x or o : marker()
3. create a function to assign a place marker : place_marker()
4. create a function to check the win , lose or tie(draw) : win_check()
5. create a function to randomly choose a player to play : random_player()
6. create a function to check valid position (position that are available) : valid_position()
7. create a function to check for replay : replay()
