Why downvote before the contest starts?
Maybe because
#pragma GCC optimizeis banned?this shall be banned, 'cause in most official contests, this is not allowed to be used either.
and, luogu is not zhengrui,
#pragmaisn't needed.In addition, we are not planning to advertise LGR-225-Div.1.5, as it is merely a simulation of the Lanqiao Cup national competition.
Although this competition has 20,000 participants in China, the quality of the problems is relatively average, and code submissions can only be graded after the competition ends. Our mock competition replicates this aspect, so the overall training value of the entire competition might not be very high, and we don't plan to announce it.
What is Lanqiao Cup? I only know Basketball Cup.

Have you ever noticed that the square bracket in almost every title of luogu_official (except for LGR 215 and 216) is fullwidth
【】instead of halfwidth[]?Same with atcoder:

This is frustrating. I've never understood how Codeforce's voting system could work like this. Is Codeforces really a chaotic system where you get totally different votes despite posting the same thing?
Examples of this can be seen everywhere, like this one. This even happens to official accounts like luogu_official! And in this post, it is literally the same thing, and there's nothing wrong with the contest (it even hasn't started yet). The worst thing is that you don't even get a reason for that.
If it's really the case, then there's no point in setting the contribution system. I don't know how you can stand this.
