8.9 (Game: Word Game) In a word-merging game, two players use their own logo (X on one hand and O on the other), filling in a space in the 3x3 grid in turn. When a player appears three identical X or three identical O in the horizontal, vertical or diagonal direction of the grid, the game ends and the player wins. A draw (no winner) is a situation in which no player wins when all the spaces in the grid are filled. Create a program to play # word games. The program prompts two players to choose X and o as their logo. When a player loses a sign, the program reappears the chessboard on the console and determines the game's status (win, draw or continue). Here is a running example:

The following is the implementation code:
