Pac-Man Game
You can copy and paste the code into a single HTML file and open it in a web browser on your smartphone to play the Pac-Man game. The game board is displayed as a grid of 10x10 characters, represented by 'P' for Pac-Man's position. Use the arrow keys or swipe gestures on your smartphone's screen to move Pac-Man in the desired direction.
