I’m finding error in re-setting the board. It displays the new board, but the positions are still occupied by X or O. It’s not seen in the program/output, but probably in the memory.

Can someone run this program on their machine and let me know how I could re-set the board so that the user can play the game again?

Thank you so much!

I tried re-setting the board somewhere below in the program (only when the user wants to play the game again) but it does not work.

I’m expecting the code to re-set the board when the user wants to play again, so that the user can place the position of ‘X’ or ‘O’ in places that were used before.

But in the current code, it does not happen.
