To my fellow Codeforces grindsets, how do you approach a 2400-rated problem when the editorial just doesn't click? At this level, detailed community writeups or custom blogs are pretty rare, let alone video editorials. So, I am pretty much stuck on this range. How do you breakthrough the wall here?

Discord helped me a lot with this, there are many CP servers where people will help you out and provide hints.

Usually the editorials feels like it’s written for people who already know it. I have seen a problem where the core part of the solution was using a custom binary search tree and the editorial simply said “for this part we can use treap” and didn’t bother to elaborate what was a treap or how and why it solved the problem efficiently. I had to ask ChatGPT providing the authors source code to understand

    Yeah, you know I feel alike, and even I used ChatGPT giving the source code lmao, but he ended up explaining the solution which somehow gives incorrect answer (and he was very confident it doing that). Though, even if he had explained me the solution correctly, I don't think it would be sustainable way.

    Do you have any other ways to wrap your head around the editorials?

Solve it directly if I can, give it up directly otherwise.

Think, think, think, then go to Luogu to seek solutions. Although Luogu's remote judgment is no longer effective, it still crawls the question statements of each CF problem and allows users to upload their own solutions (including explanations), and only those solutions that have passed the review and withstood community testing will be retained.

In this regard, a *3500 question usually has one or several solutions. Unfortunately, 99.99% of the solutions are in Chinese.

Still doesn't click? Try to check if this problem is misrated by some happenstance.

    Umm, that shouldn't be a big deal, as we've got tools for translation.

    Thanks a lot for suggesting me this new website, I'll def check it out.

    I'm not sure about the official ratings, as I started it just for fun. But, I'd like to believe in that.
