Hello CF,

UPD:

Sorry for necropost(?), but I had a lot of DMs about website being down, so I've updated it.

But the old link is invalid now, and it is hosted at: https://c2-ladders-juol.onrender.com

Thnx

I've seen a lot of people say very good things about a2oj ladders but I never used it because the problems in it are very old, as it was constructed by ahmed_aly 4-5 years ago, so I decided to try to recreate the ladders with updated data of codeforces, especially because nowadays CF is quite ad-hoc (and I like it:D).

I mostly followed the same procedure as described here, with some little changes, one of them being not having 800 rated problem in 1500 ladders, these ladders are based on problem rating. You can visit the website here https://c2-ladders.com

If you want to learn more about how I did it, I've uploaded a video on how I constructed it, which you can see here: https://youtu.be/xQuNwSFi4Ag

The website and the script both are open sources, feel free to make a PR if you want some change or just tell me in comments.

Here's a preview

Why C2Ladders? Well it stands for codemastercpp's codeforces ladders.
