For me it is this one.

This is what I see. Latex doesn't work properly for me on any problem / blog on codeforces. I tried refreshing multiple times, restaring my computer, logging out and in again and a couple other stuff. Does anybody know how to fix it?

Update: It's fixed, I didn't do anything.

Where can I upsolve problems from the Russian Olympiad in Informatics?

For people who don't speak mandarin (or whatever language is used), is there any better alternative than using google translate?

What's the most interesting beautiful you know about?

Let's say that you want to solve a problem on codeforces. Now you have a solution, but it only works for some test cases (maybe you have TLE or WA or smth like that). Wouldn't it be nice so that you could see for how many test cases your solution was right. Similar to atcoder where you can see for each category how many test cases have AC/WA/TLE/MLE.

So I suggest that you should be able to see how many test cases give each verdict. This is also really helpful if you are training for OI-style contests.

Am I the only one who feels like codeforces educational rounds are no longer so educational? The old edus seem to be way more educational.

My proposal is to make educational rounds unrated, but there will actually be educational problems.

Info1cup 2023 is coming soon and I was wondering if someone can help me translate the difficulty of the past info1cup problems to usaco/codeforces levels. Here is the archive (including the problems): https://www.info1cup.com/archive/
