By Monogon, history, 2 years ago,

Hello, Codeforces!

I'm very glad to invite you to Codeforces Round #639 (Div. 1) and Codeforces Round #639 (Div. 2). This contest will take place on May/06/2020 17:35 (Moscow time). In both divisions, you will have 2 hours 15 minutes to solve 6 problems. The score distribution will be announced closer to the start of the contest.

Of course, this round would not be possible without the help of many people, who I'd like to thank:

I've done my best to write clear problem statements and strong pretests. Don't forget to read all problems, and I hope you enjoy the round. Good luck!

Because I know you all have so many questions, I have compiled an FAQ:

• Q: Is it rated?
• A: Yes.

UPD

Here is the score distribution.

Div. 1: 500 — 1000 — 1500 — 1750 — 2500 — 2500

Div. 2: 500 — 1000 — 1500 — 2000 — 2500 — 2750

UPD Unfortunately, this contest is delayed due to problems in the Codeforces system. It is temporarily scheduled, but I will update this announcement when a final decision on scheduling has been made. It is sad that my contest is delayed, but let's be grateful that the issue was detected early instead of arising in the middle of the round. On the bright side, this may be the earliest announced score distribution in Codeforces history.

UPD The final decision on scheduling is to keep it as is. The contest will take place on May/06/2020 17:35 (Moscow time).

UPD Unfortunately due to the long queue and other issues, the contest is unrated. There was also a bug that gave us trouble in answering your questions. I'm sorry if you asked a question that went unanswered for a long time. I promise we did our best to answer as many questions as we could! Despite all the problems, I hope you enjoyed the problemset!

•  » » » 2 years ago, # ^ |   +8 good one.
•  » » 2 years ago, # ^ |   +14 I hope it means "go and increase your rating":D
•  » » 2 years ago, # ^ |   +102 +1, I had fun testing this too!
•  » » » 2 years ago, # ^ |   -62 Don't forget to read all problems It's not sorted, right ?
•  » » 2 years ago, # ^ | ← Rev. 3 →   +4 it's ok to postpone it instead of doing unrated round.
•  » » » 2 years ago, # ^ |   +39 Underrated comment

•  » » 2 years ago, # ^ | ← Rev. 2 →   +25 -looks like bait.-yup definitely bait.
•  » » 2 years ago, # ^ |   -30 sure and I have a good feel for the contest
•  » » 2 years ago, # ^ |   +257 When reds say I enjoyed solving a problem, for me, it generally means that I will enjoy reading editorial for this problem after the contest.
•  » » » 2 years ago, # ^ |   +4 quite true.
•  » » 2 years ago, # ^ |   +11 How people get the chance to be a tester for any contest? :)
•  » » » 2 years ago, # ^ |   0 Most likely you will get a message where somebody asks for your help.
•  » » » » 2 years ago, # ^ |   0 Like this is random?
•  » » » » » 2 years ago, # ^ |   +8 Well, somebody chooses to send such a message to you, or do not. So it is not really random.
•  » » » 2 years ago, # ^ |   +69 There is a channel where coordinators can ask for testing. It is not public of course. People try to cheat even without access to problems.Most authors usually ask their friends to test.
•  » » 2 years ago, # ^ |   +183
•  » » » 2 years ago, # ^ |   +6 Codeforces Round #639 lost in queues somewhere....... TRUE. But enjoyed problems.
•  » » 2 years ago, # ^ |   +21 Very true indeed
•  » » 2 years ago, # ^ |   0 very recommended :)
 » 2 years ago, # |   +41 Any specific reason for exactly 2 hours 15 minutes? :o
•  » » 2 years ago, # ^ |   +171 Yes.
•  » » » 2 years ago, # ^ |   +44 I am intrigued.
•  » » » 2 years ago, # ^ |   -8 And it is?
•  » » » » 2 years ago, # ^ |   0 Long statements maybe.
•  » » » » 2 years ago, # ^ |   +62 Ok now it's making sense why extra 15 minutes were given. But 15 minutes is very less for such long queues. Should be 6 hour contest atleast.
•  » » 2 years ago, # ^ |   +22 long queue
•  » » » 2 years ago, # ^ |   +2 long long queue.
•  » » » » 2 years ago, # ^ | ← Rev. 2 →   +13 queue < long long >
 » 2 years ago, # |   +28 Good luck for you too for 1st problemsetting. Hope we will get a new problem setter who makes good problems.Btw, the era of "is it rated?" almost ended. Now burning FAQ is "Are pretest strong? Is problem statement short?"
•  » » 2 years ago, # ^ | ← Rev. 2 →   +22 The contest is unrated! Though the problems are really good.
•  » » 2 years ago, # ^ |   +17 New one has come "Is it queueforces?"
 » 2 years ago, # |   -14 2 hours 15 minutes hmmmmMM
 » 2 years ago, # | ← Rev. 2 →   -25 wow another clear statements ans strong pretest contest <3 but ... but the contest is unrated :(
•  » » 2 years ago, # ^ |   -38 Is there any specific reason that many people downvote a comment? or just to minus my contribution?? i didn't get any point though.
•  » » » 2 years ago, # ^ |   +20 It's ok bro don't bother too much about downvotes/upvotes.
•  » » » » 2 years ago, # ^ |   +45 ok

 » 2 years ago, # |   -125 Is it rated?
 » 2 years ago, # |   +42 I am a simple man. I see "clear problem statements and strong pretests", I upvote.
 » 2 years ago, # |   -49
•  » » 2 years ago, # ^ |   +31 Nope, you still can.
•  » » » 2 years ago, # ^ |   +4 Maybe you forgot to say — "Nope, you still can. With many downvotes."
•  » » » 2 years ago, # ^ |   -79 Do you know if it's rated?
•  » » » 2 years ago, # ^ |   -44 Is it rated?
•  » » » 2 years ago, # ^ |   0 Is it unrated? :P
•  » » » » 2 years ago, # ^ |   +40 It is going to be true...
 » 2 years ago, # |   +127 FAQ is surprisingly helpful.
•  » » 2 years ago, # ^ |   +126 But it contains incorrect information.
•  » » » 2 years ago, # ^ |   -28 Why exactly is it unrated? Yes, I did read the announcement, but isn't the disadvantage the same for everyone? By that argument, the contest would still be fair.
•  » » » » 2 years ago, # ^ |   +32 Sitting through such long queue, shifting to another problem only to receive a non-AC verdict after half an hour. Incidents like this during contest is irritating. Some people give up and leave the contest. No one wants to sit through such a contest only because "the disadvantage is same for everyone"

 » 2 years ago, # |   +1 Really helpful FAQ. Thanks
 » 2 years ago, # | ← Rev. 2 →   0 Why there is Pupil in the Div.1 registration?[Edit : It's fixed now.]
•  » » 2 years ago, # ^ | ← Rev. 2 →   -12 [deleted]
•  » » 2 years ago, # ^ |   +10 I think that this rarely happens.
•  » » 2 years ago, # ^ |   +3 Probably because when they signed up, their rating was greater than or equal to 1900， but after a few contests they scored lower
•  » » » 2 years ago, # ^ |   +4 That's only true for the Expert in the registration. What I mention is Pupil in the registration, and it's virtually impossible after the registration CM becomes Pupil because the registration is opened usually within 2 days before the contest. :(

 » 2 years ago, # |   -75 isitrated?
•  » » 2 years ago, # ^ |   0 Are you kidding?
•  » » 2 years ago, # ^ |   0 now you're right about asking that question
 » 2 years ago, # |   -13 Many experts are registered in Div 1 contest!How? And I knew that candidate masters are participants of div 2 contest.Also I was rated in last div 2 contest.But today I can't register for div 2 as rated one.Why?Actually,I'd been candidate master recently...Thanks
•  » » 2 years ago, # ^ |   0 Understood the system of my second question.
•  » » 2 years ago, # ^ |   +4 The experts who are registered for div1 were candidate master before round #638 rating change. They registered for contest before rating change so they are registered in div1. After rating change there rating decreased to less than 1900. This might be the reason behind invalid registration which will be hopefully fixed before contest.
 » 2 years ago, # |   -16 are problems sorted?
•  » » 2 years ago, # ^ |   0 Yes, the problems are sorted by difficulty.

 » 2 years ago, # |   0 One general question, why do some Legendary Grandmasters have the First Letter of their initials as black and rest of the name as red? What does the Black character signify?
•  » » 2 years ago, # ^ |   +51 It looks cooler.
•  » » 2 years ago, # ^ |   0 The Legendary Grandmasters have rating over 3000,but the International Grandmasters don't
 » 2 years ago, # |   0 People whose rating crossed 1900 in the previous contest are still in the participant list of Div2 will they be shifted to Div 1 during the contest?
•  » » 2 years ago, # ^ |   0 No, Codefoces takes the rating when you register. If you have a rating of lower than 1900 and you register, then you get over 1900 after you register and before the competition, you are still a division 2 participant.
 » 2 years ago, # | ← Rev. 2 →   -16 Must say the FAQ is very informative.... must have been hell lot of a job for the writer!
 » 2 years ago, # |   0 I am curious about the duration of the contest!!!Can I get the explanation???
 » 2 years ago, # |   +3 I hope this contest will also have short problems and strong pretests like the previous one, At least strong pretests.
 » 2 years ago, # | ← Rev. 2 →   -12 Q: Will it be some live stream on YouTube to up-solve the problems straight after contest?A: Algopedia: https://youtu.be/HneuObfyDtw
 » 2 years ago, # |   -6 Auto comment: topic has been updated by Monogon (previous revision, new revision, compare).
 » 2 years ago, # | ← Rev. 4 →   0 Why are there two problems with the same score in Div.2 but not in Div.1?UPD: Sorry for my mistake. I'm used to putting the score distribution of Div.2 at the top when I prepare contests. And personally I think that looks better because the problems are in increasing order.
•  » » 2 years ago, # ^ |   0 The two problems with same score are in Div. 1, not Div. 2.
 » 2 years ago, # |   0 Div 2D is again 2000 points. :( That did not go well for me in the last contest.
 » 2 years ago, # |   +11 new to CF, so can anyone tell me what the score distribution means?
•  » » 2 years ago, # ^ |   +8 every problem comes with a different score based on difficulty. as the contest proceeds the score of every problem keeps on decreases.

 » 2 years ago, # |   +3 Auto comment: topic has been updated by Monogon (previous revision, new revision, compare).
 » 2 years ago, # |   +5 Just curious if there's any specific reason why the score distribution is not announced much before the contest??
•  » » 2 years ago, # ^ |   -6 So that people cannot pre-plan strategies or try to guess their way out about the problem difficulties I guess.
 » 2 years ago, # |   0 Hi, i have a question. The score distribution of div 1 is less than div 2. Why is that?
•  » » 2 years ago, # ^ | ← Rev. 4 →   +2 Why down voting when someone asks question? I know its not the place to ask and his question is literally trash.
 » 2 years ago, # |   -6 Auto comment: topic has been updated by Monogon (previous revision, new revision, compare).
 » 2 years ago, # |   0 In general, are you allowed to write a program that basically makes your submission unreadable so it is harder to hack? For example, the program can add comments, remove/insert whitespace, etc but it doesn't change that basic functionality of your submission.
•  » » 2 years ago, # ^ |   +22 No. Code obfuscation is explicitly prohibited by Codeforces rules.
•  » » 2 years ago, # ^ |   +65 So the question is WHY don't you want others hacks your program?If your program really has a bug, others may find it out and correct it for you. Thus you can fix it in the contest in time instead of receiving an unexpected WRONG ANSWER verdict. This case is profitable for you and others.So my advice is: TRY to write clean programs. (Although I'm still not good at it :v)
•  » » 2 years ago, # ^ |   -55 Lol. Why is the score distribution for Div.2 higher than that of Div.1?
•  » » » 2 years ago, # ^ |   +7 Because the div1 guys just act if they would have the harder problems ;)
 » 2 years ago, # |   -15 Thanks for the faq. Much appreciated.
 » 2 years ago, # |   -10 Today, i got notice for an internal test (online ) from my college which clashes with this contest . After waiting for 3 days i have to skip this contest , hope its timing can be changed :-(

 » 2 years ago, # |   0 You can catch my (little) rate. I'm give up for this constest.
 » 2 years ago, # |   +27 The long queue makes it really difficult to analyse the bugs(if any) on wrong submissions since the verdict comes after a long time. This really affects the aura of the contest. Though the efforts put by the contest designers and testers and also by you Mike are great, please consider making this contest unrated.

 » 2 years ago, # |   +78 I really feel sorry for the problem setters, the round was delayed in order to fix everything and still it ends in this horrible way :( I am not blaming Mike thought, I am sure they did their best :(
•  » » 2 years ago, # ^ | ← Rev. 2 →   +3 But then, this is life. We can just put the best of our efforts!

 » 2 years ago, # |   +11 Make it unrated already!
 » 2 years ago, # |   +48 Refresh is the new Logout!!
 » 2 years ago, # |   +89 Because I know you all have so many questions, I have compiled an FAQ: Q: Is it rated? A: Yes. Really!?
•  » » 2 years ago, # ^ |   +2 I know right, so ironic.
 » 2 years ago, # |   0 please make this round unrated
 » 2 years ago, # |   +10 The round should be unrated. Even now, I have been experiencing severe session issues. (i.e., I'm being logged out automatically) Even when I go to the m1.codeforces site, the queue is so long that the code I have submitted for Div2 B is not judged in the time I read, conceived, and submitted a solution for Div2 C. Update: The first one was judged after 30 minutes.

 » 2 years ago, # |   +4 We need quantum computer as soon as possible
 » 2 years ago, # |   +207
 » 2 years ago, # |   +4 This is by far the worst queueforces ever !!
 » 2 years ago, # |   +7 Why the questions about the problems and during the contest are not answered by the problem setters?
 » 2 years ago, # |   +21 Rank 6, +148, and with Div1.D in queue --**unrated**
 » 2 years ago, # |   +7 This round should be unrated.
 » 2 years ago, # |   +10 I Think We have reached 35 minutes of queue. Unrated Contest seems to be inevitable now
 » 2 years ago, # |   +56 Waiting for a submission verdict be like:
 » 2 years ago, # |   0 The judge queue is too long. I have to wait almost half an hour to get the answer. This is the most uncomfortable Codeforces Round I have ever participated.
 » 2 years ago, # |   +7 Is Div2 also unrated or not? Div1 got an unrated announcement but not Div2, not sure if I should discuss problems with friends who are in Div2 or not.
 » 2 years ago, # |   +86 Mike: We have rescheduled the contest to avoid long queues.Users right now:
 » 2 years ago, # |   +30 took 30 min to get result of a submit. got WA. spotted stupidest mistake. submitted again. Is it a way to show that we have to be reaaaaaly careful with our submits? Otherwise getting 30 min penalty :D
 » 2 years ago, # |   -12 Long queue + Bad problem statement
 » 2 years ago, # |   +1 Worst Experience on codeforces ever.... I had to login more than 10 times during contestI think MikeMirzayanov should take it seriously bcz it annoying the contestant.
 » 2 years ago, # |   0 is Div2 still rated? As there is no such announcement in Div2
•  » » 2 years ago, # ^ |   0 Now i got notification that it is unrated and just solve the problem for fun :)
 » 2 years ago, # |   +182
 » 2 years ago, # |   +81 Ok, this is too much. Situations like this happen too frequently on Codeforces. Maybe we should donate even more so you can stop this from happening every 3rd contest or so?Dear problem setters, please submit your problems to other, more stable platforms. The quality of your problems deserves much more than this.
•  » » 2 years ago, # ^ |   -14 i mean they could have just added advertisements to codeforces to keep more servers? also I heard they use Windows servers for testing. Maybe Linux would work better? idk
•  » » 2 years ago, # ^ |   +34 I don't know why people complain about cf when it has bad rounds. It's not so frequent for rounds to be unrated in such a way, when was the last unrated round because of queue issues? Surely not 3 contests ago ... It's hard times for codeforces too, number of participants in rounds doubled during pandemic. And I think at this time we shouldn't have such negative thoughts about cf.
 » 2 years ago, # |   0 Can we have a contest with hidden verdict?
•  » » 2 years ago, # ^ |   +11 No
•  » » 2 years ago, # ^ | ← Rev. 2 →   -7 In China, we have 'OI' contest rules, and it works as follows: Participants are allowed to submit multiple times, but only the last one will be judged. The submissions will be judged after the contest, so you cannot know the vertict during the contest. Chinese OI rounds, please.
•  » » » 2 years ago, # ^ |   +75 I hate null feedback rules. Newbies should especially hate them.
•  » » » » 2 years ago, # ^ |   -14 In fact, the first time I see the long queue, I have pretended to participate in OI rules, and because I have participated in so many OI rounds in China, it seems perfect!In addition: I would probably become 2900+ had this round been rated.
•  » » » » » 2 years ago, # ^ |   +52 That's real bold, calling your rating increase based on 0.5 hours of evaluated submissions before the round was announced to be unrated. I've also had very good results in some quickly unrated rounds, guess why.How about this: make your own website where you'll host contests with these rules. I'm sure all the Chinese LGM-tier contestants will appreciate it for the same reasons as you do.
•  » » » 2 years ago, # ^ |   +2 That looks similar to what Topcoder does.
•  » » » 2 years ago, # ^ |   0 Is there any Chinese website like CF or AtCoder?
 » 2 years ago, # |   0 If this round is still rated, I think it is really unfair for contestants as the judging time is too long. It took more than half an hour for a single submission!!!
•  » » 2 years ago, # ^ |   0 It isn't rated now
•  » » 2 years ago, # ^ |   0 It's unrated.
 » 2 years ago, # |   0 wtf
 » 2 years ago, # |   0 Offlineforces:/
 » 2 years ago, # |   +51 Mike: Coronavirus, can't get into our systems. Becoz its not the software based virus, it's a physical one. Corona: Causes lockdown worldwide, increases the number of participants in contests, blows up servers. Mike: wtf !
 » 2 years ago, # |   +29 The problems are so cool, so it's a pity that we can't enjoy them completely because of the long queue :( I hope that everything will get better. Live Codeforces!
 » 2 years ago, # |   0 as expected round is unrated sed lyf :((
 » 2 years ago, # |   +15 Because I know you all have so many questions, I have compiled an FAQ:Q: Is it rated? A: Yes. Mike: Actually, no.
 » 2 years ago, # |   +1 This is what happens when the contest is postponed by 3 days---> Unrated
 » 2 years ago, # |   +6 the answer to FAQ turned out to be wrong
 » 2 years ago, # |   -6 Besides the long queue, why the overlap between div1 and div2 is too high? So if someone solves all problems in div2, they could be top10 in div1.
•  » » 2 years ago, # ^ |   0 Do you really think it's so easy to fc div2? Pfft, please...Anyways, if this was actually a rated contest without the queue issues, div1 top 10 will definitely not be 4 ACs by end of contest (it's a six-problem round, probably at least 10 people will solve E or F). So your point is pretty much invalid.
•  » » » 2 years ago, # ^ |   0 Read my comment again. I talked about the high overlap not being easy of solving all problems.
•  » » » » 2 years ago, # ^ |   0 That's the norm for how div1 and div2 rounds work.The easiest two problems are only in div2, while the hardest two problems are only in div1. Given that the two divisions are directly touching ranges of rating, the overlap makes sense in balancing the difficulty of the divisions.Also, your premise is that "if someone solves all problems in div2, they could be top10 in div1", which is itself a flawed premise because 1. fc in div2 is actually quite rare, and 2. top 10 in div1 only solving 4 problems is also quite rare.
 » 2 years ago, # |   +3 Now you know how a TopCoder SRM feels like
 » 2 years ago, # | ← Rev. 3 →   +21 Declared unrated now. Feeling bad for the contest organizing panel. Though it was a bad experience for all of us, but I still appreciate Monogon along with the whole contest organizing panel for their efforts. It is not easy to be on the other side of the table. Thank you!
 » 2 years ago, # |   0 i submitted sol of a in 8 min but it was not showing in submission tab there i reload the page several time around 10 min because i was continuously logged off and my submission was not showing in tab and also not showing in queue either therefore i resubmitted again .and after 5 min of reloading i see two of my solution in queue! miracle ! REWARD -50 points(resubmission) and headache/tension. if site cant handle too much traffic just make more divison to handle lesser participants per division. AGAIN SED LYF MONOGON .
•  » » 2 years ago, # ^ |   +7 That's... not how divisions work?
 » 2 years ago, # | ← Rev. 2 →   +63 The irony is that the one question answered by the FAQ has been answered wrongly.
 » 2 years ago, # | ← Rev. 3 →   -66 thanks for wasting my time !!
