rematch | redux best practices | State Container library

I am making a code which takes in jumble word and returns a unjumbled word , the data.json contains a list and here take a word one-by-one and check if it contains all the characters of the word and later checking if the length is same , but the problem is when i enter a word as helol then the l is checked twice and giving me some other outputs including the main one(hello). i know why does it happen but i cant get a fix to it

Context: I want to have an action that calls two other actions, so I made an effect. Within this effect, I need to access the rootState. I read that the second argument of an effect must be the rootState, but if there are no arguments, the rootState is still passed to the effect.

This works and will print out rootState (however I have no need for a payload):

For a 1v1 Sudoku game, my GamePage component renders the main Game component, which contains a Clock for each player. When both players agree to a rematch, the entire Game is reset by simply incrementing its key by 1 (after changing the GamePage state to reflect the settings of the new game).

My Problem:
Game stores two refs this.myClock and this.opponentClock to the countdowns inside of both clocks, so they can be paused/started when a player fills a square. This works perfectly fine for the first game. However, after Game remounts, any move will throw "Cannot read properties of null (reading 'start')" at e.g. this.opponentClock.current.start().

I know that refs are set to null when a component unmounts, but by rendering a new version of Game, I would expect them to be set in the constructor again. To my surprise, the new timers are set correctly and one of them is running (which is also done in componentDidMount of Game using the refs), but any access afterwards breaks the app.

I would be incredibly grateful for any tips or remarks about possible causes, I've been stuck on this for two days now and I'm running out of things to google.

GamePage.js:

I’m creating a Shiny app that uses the caret package to do some SVM free-text analysis.

The app runs fine without any error in my computer. I’m using R x64 4.0.4 and R studio 1.3.1093

I’m deploying app to an internal enterprise server https://rconnect.xxxx.com/connect/#/apps/####

This app is deployed in the server and started.
But when I reach the line where I run the train function:

I just upgraded from typescript 4.1.2 to 4.3.2 using Rematch. These rematch packages are used:

• "@rematch/core": "2.0.1"
• "@rematch/select": "3.0.1"

and I faced a typescript error: Type never has no call signatures. I looked into the 3rd parties' code and found that RematchDispatch gives never type when I have a reducer and an effect in a particular model with the same name. For example:

This is my first question here, I hope that It doesn't sound stupid. So I'm trying to find a way to get the index of the first character from a string that matches the regular expression. I made my research in the regex reference in cplusplus.com but I wasn't able to find anything (probably my fault). For anyone that still don't understand what I want to do, let's make a small example, I have the following code:

The problem: Have a long string of text and need to extract the date out of it. However, the string has multiple dates so certain conditions should be met to succeed.

The strings with date fragments within the text are as follows:

of Los Angeles 12/19/2018 11:39 AM She
as a Unit 1/18/2019 8:30 AM 4 1.

Using the regex below I can match two dates:

I have a UFC database and I'm looking for rematches. Therefore, I need to find the duplicate combinations of names; the combinations that appear more than once. However, since the winner of the first fight could lose the rematch, I need to find duplicates regardless of the order in which they appear.

This is how my database is structured: database example. Fighter 1 is the winner and fighter 2 is the loser.

Here is a link to the database (got it from kaggle): https://docs.google.com/spreadsheets/d/19ISNhYFdGzgLZz1x4h2v_Q5Pq0cofw2rkUtwk3xPXGQ/edit?usp=sharing

Feel free to play around with it.

Any ideas on how to solve this?

Here is an example of the result I'd ideally want:

image example

Just a simple highlight over the duplicates.

This might be a question that is kind of dumb but I'm trying to construct a model that is able to filter out inputs before feeding the filtered output to another network.

For example, I have an image that I would to match with a database of about 100 pictures, then I would apply the first network to do some operations that would output the top 10 pictures that is most likely to correctly match. Afterwards, I would apply a second network to rematch those top 10 pictures using a secondary network.
