Input Not Validated for Non-Numeric Values

Title:
Crash on Non-Numeric Input

Description:
When a player enters non-numeric input for the row or column, the game crashes. The program does not handle invalid input types (like letters or symbols), causing it to terminate unexpectedly.

Steps to Reproduce:

Start the game.
Enter a letter or symbol instead of a number when prompted for the row or column.
The game crashes.
Expected Behavior:
The game should prompt the player to enter a valid numeric value instead of crashing.

Suggested Fix:
Use input validation to ensure only integers are accepted for the row and column inputs.

Look for the code that reads player input for row and column, likely in a main game loop or input function. Add validation to check if the input is a valid integer before processing. Test by running the game and entering letters or symbols to ensure it prompts for valid input instead of crashing.
