tictactoe | Tic Tac Toe Machine Learning | Machine Learning library

I am trying to make a Tic Tac Toe game in Python, where I use two separate files. Each has different code and separate classes, which I am trying to call. However, each time I try to do so, I receive this error:

I have a react app that fetches data from an API. The data fetched is a string.

One example of such a string is,

I am currently doing this problem in cs50 AI where we need to make a minimax algorithm for playing tictactoe. My algorithm doesn't work at all (it is really easy to beat the computer) and I was wondering what I was doing wrong. I am also pretty sure that all my other functions are correct and that only the minimax function is incorrect. Would really appreciate any help, thank you all!

The state of a value set using React useState hook gets set to the proper value and then reset to null. Critical code below. The click event that sets the startDate to the current date and time is 3 components down from where startDate is initialized. When setStartDate did not work I created an arrow function, updateStartDate. Both had the same problem where the startDate was changed after the click event (witnessed per the console.log in the top component), but was null just before the next click event (per the console.log in the click event). This is not an async problem as I see the change made before subsequent click.

If this is something that just does not work please explain. I could probably fix with useReducer but prefer to keep the useState if there is something I can do to correct this... If not correctable then I would like to at least understand why it does not work so that I can avoid this problem in the future.

I've just started studying Java.

I know I can extract a jar file with command jar xf jarname.jar

But I'm confused about this [command jar x and useless new lines]jar x and new lines

1. Enter jar x，press the Enter key.
2. Enter TicTacToe.jar(what i want to extract sth from),press the Enter key.
3. Nothing else happened expect generating a new line.

Please tell me why

Can't 'x' be used by itself?

Or

I should use some special command in cmd？

I am writing a modified TicTacToe game where the user has to enter a correct response before their selected square receives an "O" or "X". I have this working fine with two live players on the same computer. When I add the ability for one player to play against an automated response I am having trouble placing the "X". I can calculate the best square(row and column) to place the, "X", but am having trouble displaying it on the board. Below is the code that displays the buttons. The board layout can be a square of any number between 3 and 10.

I track the coordinates (data-coord) of each square but do not know how to use the row and column to place a square in the button group. I do not have a click event for the automated user but if there was a way to simulate the click event at the selected location then I could place the "X" similar to how the live user's selection is updated. Can you please provide any suggestions for doing this?

I am trying to understand the Tic Tac Toe game code from Programming In Haskell by G. Hutton. The code is in the file tictactoe.hs. On Windows it generates these characters (←[2J←[1;1H) at the beginning of displaying the game grid. It doesn't happen on Ubuntu.

So for a TictacToe game I would have a nested array in the state, like this:

I use the Firebase real-time database to store the stats of several games for my Discord bot and would like to calculate the high score for each game independently.
