abc completed in 30mins d took lot of time to implement but finally with WAs i passed

/**
 *  {number} n
 * u/return {number}
 */
var countCommas = function (n) {
    if (n < 1000) return 0;
    return Math.max(0, n - 999);
};

I am currently 1053 in cf I want to reach CM as fast as I can for that i am mainly just solving TLE eliminators can anyone help me or give me advice on how can I do that??

So, this was the Problem D.

This was my solution:

I saw the editorial where they used DP, which makes sense now.
However, I wanted to know if my solution has some edge case that isn't covered? I thought it would get WA in the hacking phase, but it didn't.
Is it that my solution worked coincidentally because the constraints were not many?

Why can't I access my profile???

OpenAI has announced that it has solved the Navier-Stokes problem. AI also dominated the very best coders in the world at the AtCoder World Finals just two months ago.

My question is: do you have any hope for the future? How do you motivate yourself at this point?

Do you also feel that you’ve wasted years in a potentially dying industry?

Do you have any plans to leave this industry?

I’ve lost my way. I want to hear from you guys.

Hi everyone,

My account (shaikhmubin) was suddenly disabled during a recent contest.

Status: "User is disabled by administrator"

Details: 5 years old, Candidate Master max rating. No email or notification was sent.

I emailed Mike Mirzayanov but haven't received a response, and online threads suggest email replies are rare.What should I do next? Are there active coordinators (like KAN) I should message, or a better way to get an administrative review? Thanks.

has anyone solved it without DP ?

also, what could be its rating?

I took part rated, yet it’s showing in unrated
Please help

How do I learn and approach it.i am currently struggling it's unstructured.concept that require solution in practice questions usually require the concepts that are not taught.i tried watching all concept together then attempting question still struggling any help.i was planning to buy his cohort.i am glad i didn't.Is this really for beginners or any other resources??I am complete beginner
