SetRank | source code , dataset , and evaluation scripts | Machine Learning library

So I'm new to C++, so bear with me here. I'm trying to read a csv file and parsing the data into smaller strings to hold in my class. As I attempt t do this, I come across a problem with stoi(). Every time I try to convert my string to an int, I get an error "terminate called after throwing an instance of 'std::invalid_argument' what(): stoi".

I have tried checking to see if my string is an actual number and it is. I have checked if there is a space or any other weird character, there isn't. I'm not sure what's wrong. Guidance will be appreciated.

Edit: Here is my code

I am new to React and I try to implement following code where I get axios response:

There are total scores of athletes. I want to sort the list by total scores and add the position (place) to position field. In case of equal scores, athletes must share the places, e.g. 3-4 and 3-4 instead of 3 and 4.

I'm setting up Slash Commands with my Discord.JS bot.

I have a /rank command in the XP/leveling portion of my bot, but when I check interaction.member.presence for displaying it in the rank card, it returns null.

I've tried to look up this problem and look through the documentation of Discord.JS, but nobody else seems to have had this problem yet and I don't see anything in the documentation or Discord.JS guide to help solve this problem.

Here is the /rank command:

I am trying to create a table and I am getting an error, I don’t know why. I thought it was because of the float, but my Field table has a float and is being generated correctly.

I was trying to change dialect or create-drop property. But it does not help me. So i really don’t know what to do.

Also, I thought column rank is cause of error, but i don't know why

I'm in the beginning of learning Reactjs and I am searching for some tips and tricks on how to improve following code structure (For now I'm only using sample data as values for the different states):

After submitting with UpdateParams, the new url is called and a JSON object with the new queried data is returned as expected.
The form updates the two state vars.
However, the products in the all-products view are not updated to reflect the form input.
What do I need to do to to refresh the render to reflect the new data in product?

I have an ArrayList of a custom class named 'Team'.

Every object of 'Team' has an attribute of 'setsWon' with a value assigned.

Team also has an attribute of 'rank', that is set to null. I want to find the 'Team' with the largest number of 'setsWon', and assign 'rank' to 1, and then find the second largest 'setsWon' value, and assign its 'rank' to 2, and so on.

I have attempted, but i receive a null pointer exception, and its because I am only able to assign a rank to the largest 'setsWon' Team, and not any others.

this is my attempt:

I am trying to implement the Android Bubbles notifications API but it's not working for me, it's displaying as an ordinary notification. I am testing on emulator API 30(Android 11). I got the people-example working on the device, and I am following the Conversation Notifications guidelines.

• The notification uses MessagingStyle.
• (Only if the app targets Android 11 or higher) The notification is associated with a valid long-lived dynamic or cached sharing shortcut. The notification can set this association by calling setShortcutId() or setShortcutInfo(). If the app targets Android 10 or lower, the notification doesn't have to be associated with a shortcut, as discussed in the fallback options section.
• The user hasn't demoted the conversation from the conversation section via notification channel settings, at the time of posting.

Please tell me what did I missed?

Also, I got a few optional questions about the design of Bubbles.

• At what point of the app should I create the shortcuts and when to update it?
• How the Person object needs to be cached?

This is what I got so far
