How to Participate in Luogu Contests **UPD**: (From [user:MatrixGroup,2024-07-13]) To copy Markdown for discuss and articles, you can: For discuss, use the code: ``` console.log(_feInstance.currentData.post.content); ``` For articles, use: ``` console.log(JSON.parse(document.getElementById('lentille-context').innerText).data.article.content); ``` *** Luogu is a famous OJ (Online Judge) in China. Many users of Codeforces may know it, but don't know how to participate contests on Luogu. So I'm writing this blog to offer a brief tutorial. I suppose that you do not have a Luogu account, so let's start from registering. ### Step 1. Create An Account Enter the site: [link](https://www.luogu.com.cn/auth/register) Here is the English translation for this page.  You need to fill in: + username, + password (and confirm), + the secret code in the picture, + your email, (and click the "send verification code" button) + chec...

One final blog about Codeforces Round 1033 and CodeNite 2025 Hi everyone, writing this blog after the recent rollback, getting red back to top of leaderboard as everyone so much desired, and making the overall leaderboard so much better. If you disliked the announcement/tutorial of [contest:2120] or posted a genuine critique because of problem quality or or because of some other situation which we could've improved, then this blog is not for you, I don't have any hard feelings and understand why you did it. The dark side ------------------ First of all, everyone who cheated in the round, I really reprimand you all and hope you all are fairly retributed for what you all made me go through and the deeds you've done. I especially hope all those who run the back alley solution distribution during the contest are gone for good and that they are especially retributed for their wrongdoings. (I don't think we can stop GPT or that it can suffer "retribution", so not sure what to say about it. Anyways, people who use GPT for wrong are responsib...

On contest announcements with many downvotes _Mwa ha ha ha ha I'm the mad sports programmer (sp) Hououin Riela! The organization is acting again, and as consequence the last round was unrated. However I'll break the convergence to change the worlds control structure._ The last cf round was an important one ― it is part of a tournament. However it was unrated because problems with the servers, many people downvoted the announcement post simply because the contest was unrated, however the problems were interesting. It is not the fault of the setter that the round ended unrated, and a decrease in contribution can be demotivating. I know that contribution is just a number, but I would be affraid that if I set a round and there is a problem with the servers, then my post will be heavily downvoted. Do you think is a good idea to remove the downvote button for cf round annoucements? what other solutions do you propose? I think removing the downvote button is good, because there is no sense in downvoting those kind of posts. ...

About Teams Participating in Online Mirrors of ICPC-Style contests It is well known that in onsite ICPC contests, the team members have to share one computer. However, I've been always confused that whether it is also true for Codeforces online mirrors of ICPC-style contests. I have chosen two of the ICPC-ruled contests on Codeforces. [COMPFEST 15 &mdash; Preliminary Online Mirror](https://mirror.codeforces.com/contests/1866): As mentioned in [this comment](https://mirror.codeforces.com/blog/entry/119883?#comment-1064891), all teammates are **allowed** to use their three different computers at the same time. [Online mirror of The 2023 ICPC Asia Jakarta Regional Contest](https://mirror.codeforces.com/contests/1906): As mentioned in the [announcement](https://mirror.codeforces.com/blog/entry/122754), it is **encouraged** to participate as a team using only one computer for coding. Since currently there is no annoucement for the coming online mirror of 2024-2025 ICPC, NERC, Southern and Volga Russian Regional Contest, I sincerely ask here: is it allowed for each team membe...
