DEVELOP A SEQUENCE DIAGRAM TO DISCOVER THE OBJECTS. THEIR RESPONSIBILITES, AND THE MESSAGE THEY RESPOND TO

When a new game is created, two players register with it by name (the arguments to Game.new). The play_game message is called with one of the players names and starts a new game where that player plays first using the O marker. (A game can be sent repeated play_game messages so the same pair of players can play multiple games). In each iteration, the current player is prompted for the position of her move and then she enters the move number, where the nine squares are numbered in row-major order from 1 through 9. If a move is illegal (i.e., already occupied), the current player is scolded and prompted again for a move. After each move, the board is redrawn. A game ends when either one of the players forms a horizontal, vertical, or diagonal row of her three markers (in the usual way), or the board is full indicating a tie. If the current game is not over, the current player is prompted for a legal move which she supplies and then the move is made and the current game board is displayed.
