Tokio Marine & Nichido Fire Insurance Programming Contest 2020 E - O(rand)
居然真的有人用\(O(rand)\)的算法水过了这题……亲测可以被极端数据卡掉。
C - Domino Quality
本来是还真有人想出了纯构造算法：Detail
AGC045
史上最难的一届AGC（看榜），我只做了A，居然Rating还升了。（第一道400分的题居然是道线性基，这你敢信？？）
ABC137D
题解：
：夏休みにお金を稼いで沖縄旅行に行きたいという気持ちで解くと解きやすいかもしれません。（百度翻译：以暑假赚钱想去冲绳旅行的心情来解题的话可能会比较容易）
Google Code Jam 2020 Round 1C - Robot Programming Strategy
官方Analysis：
Round 1C continued this year’s Round 1 pattern of one “easier” regular problem, one “medium” interactive problem, and one hard regular problem. Robot Programming Strategy laid out a tournament structure that might have seemed hopelessly complicated at first, but the details turned out to be mostly unimportant — your robot just had to be able to win against any opponent! Like Draupnir in Round 1B, Power Arrangers made you infer some missing information after making careful choices. Finally, Bacterial Tactics could be approached with a useful tool for solving problems about two-player games.
By the 25 minute mark, every problem had been fully solved by at least one contestant, and the race was on to get that first 100 score! Rafbill initially appeared to come out on top with a penalty time of 50:57, but later resubmitted and slipped to an overall third place, with a penalty time of 1:07:44. logicmachine — now that sounds like someone who knows a thing or two about robot programming strategy! — moved up to win with a penalty time of 54:07. Joisino took the silver with 58:48. There were 91 perfect scores overall.
Rafbill在这题上面交了两遍，第二遍提交使得他Rank1->Rank3……
原来的实际上是对的……只是他分析错了，以为不太正确。所以后来改得保守一点，又交了一发……(实际上，如果按照他的分析，是可能TLE的……)。
而且后面交的那一发还把原来的代码改丑了（加了两个玄学优化）……
ABC133C - Remainder Minimization 2019
有谁能帮忙hack一下这个玄学算法吗……
ECNU2019L - Liwa River
太阴险了……在最后一题放一个比较水（但是不容易看出来）的贪心题，还用非常长的题面去掩盖他……

震惊！某选手因为担心编译出错竟做出这种事……

Google也有打错字的时候啊[doge]。
so it has no memory of the that match.

If I were a Thanksgiving Turkey...
I would look for aspen trees with holes inside them and look for my turkey brothers
I would listen to crazy, trigger-happy hunters yelling at young turkeys and shooting evil flares

If I were a Thanksgiving Turkey...
I would smell like poop and not to be eaten but to be eaten by the dumb, mooing cows
I would taste like pig mud with a lot of salty parts
I would be stuffed with absolutely nothing. No one likes me to be eaten (except the pudgy animals, of course)
I would wish to be a happy, wet crocodile
I would think what I have done wrong in my previous life.
Codeforces上的“种族歧视”
如https://codeforces.com/blog/entry/91114：
Also, one last tip: I've noticed it observing all the top people on Codeforces/Atcoder. None of them uses the word "question" instead of "problem"/"task". So don't do it. You won't progress if you'll keep calling problems "questions".
见https://codeforces.com/blog/entry/91114?#comment-795590
I solved more than 1341 problems till difficulty 2200 but no improvement at all , I feel frustrated should I quit?
这个帖子的存在本身。（不过这个帖子确实提出了一个有价值的问题）
On Problems vs. Questions in Competitive Programming: My solution
前情提要：Codeforces上因为对使用Question指代OI题的印度人的歧视而吵起来了。
解决方案：
TL;DR: The most reasonable solution to the problems vs. questions debate is to use none of the currently accepted terms.
用bugaboo指代题目。
As a bugaboosetter, I approve this message.
