Hello, Codeforces! Were you afraid of the lack of contests? We also!
Unfortunately, due to technical problems, the round is declared unrated. You can continue to solve problems, but the results of the current round will not affect your rating. We are sorry for this situation.
<almost-copy-pasted-part>
Hello! Codeforces Round #697 (Div. 3) will start at Jan/25/2021 18:00 (Moscow time). You will be offered 7 problems with expected difficulties to compose an interesting competition for participants with ratings up to 1600. However, all of you who wish to take part and have a rating 1600 or higher, can register for the round unofficially. The round will be hosted by rules of educational rounds (extended ICPC). Thus, during the round, solutions will be judged on preliminary tests, and after the round it will be a 12-hour phase of open hacks. I tried to make strong tests — just like you will be upset if many solutions fail after the contest is over.
You will be given 7 problems and 2 hours to solve them.
Note that the penalty for the wrong submission in this round (and the following Div. 3 rounds) is 10 minutes.
Remember that only the trusted participants of the third division will be included in the official standings table. As it is written by link, this is a compulsory measure for combating unsporting behavior. To qualify as trusted participants of the third division, you must:
- take part in at least two rated rounds (and solve at least one problem in each of them),
- do not have a point of 1900 or higher in the rating.
Regardless of whether you are a trusted participant of the third division or not, if your rating is less than 1600, then the round will be rated for you.
The problems for this round were invented by MikeMirzayanov and prepared by me Supermagzzz and Stepavly
Thanks to MikeMirzayanov for platforms and coordination of our work. Thanks to darkkcyan, Tzak, bfs.07, songsinger, iankury, spookywooky, Programmer, sodafago, infinitepro for help in round preparation and testing the round.
Good luck!

UPD: Editorial is ready!
7 Problems!!! Great.
Contest start's 15 minutes late
why?
looks like there was some issue with the servers. the site was showing unavailable for me for some seconds.
Codeforces teaching us how recursion looks like
10 more minutes late cant wait to start
I thought my internet connection was down
A small suggestion, keep an tab open of m1.codeforces.com aside. It might help.
29000 registrations!! they must be adding some resources
Maybe they are waiting for the number of registered participants to cross 30k :0
Kind of hard for the round setters.
was fully set to give the contest and the enthusiasm drops down immediately after hearing of delay.Need to think of something to pass time now.Hope to get some upvotes to increase the enthusiasm
Same
please dont do this to me this is my first comment

Some brazilian testers, this is great!
Best of luck to all.
Hope this contest will increase our rating!! Finger crossed.
I will try my best to reach pupil today. All the best to all participants.

Thanks for the contest.

My chance for specialist
How can I become a tester for Div. 3 contests if I am not a friend of the testers/setters?
I am not a friend of either of them. I think it's pure random ;)
Thanks for your reply!
Since I am less likely to give CP contests in the following few months, it would be nice for me to contribute to the CP community by becoming a tester for Div. 3 contests.
I would want to become a Div. 3 contest tester in the future — if Stepavly and Supermagzzz would want me to provide feedback for your contests, please give me a call!
Well, this time each tester has a ten years badge.
.
I am waiting for a div2 round
I am waiting for a div2 round that is unrated for me :)

"Care" of course

well, time to pay up :)
ugh, but i guess it doesn't count since my statement is technically incorrect?
What extension or script do you use to highlight submissions based on language?
Codeforces Enhancer
Would you please provide me the link or more details about is.
google it on chrome's store.
Blog of codeforces enhancer
I am sure nobody likes to see this.
Yes please help to downvote this upper comment so that it won't visible again
I don't like seeing <"almost-copy-pasted-part>"
That Irregular Bracket Sequence :V
+50 points for the hack.
As you can observe now, its_Atrap
As a tester, I recommend participants to open
https://codeforces.com/contest/<contest-id>/problems
rather than opening each problem page, during the contest.Reduces clutter and server load (ig).
Thanks sir, for this new bit of information.
Can u tell us where we can find the contest-id for contest before the start of the contest Thank you
Enter any contests and you can find the contest-id in the URL.
Edit: You can still find the contest-id in the
and it is
/contestRegistrants
route by clicking1475
for this contest. Luckily, the id gets incremented by one in each contest but you can't enter the contest before it starts.Actually there are two more or less direct links:
This one links to the contest, but currently forwards to this blog, since the contest has not been started yet:
https://codeforces.com/contest/1475 and is equivalent to the inline link Codeforces Round #697 (Div. 3)
That one links to the page where you can register for the contest:
https://codeforces.com/contests/1475
That second link is also used in Calendar
Nice but have you ever noticed
www.facebook.com
middleware?damn it i just got rick rolled
the real rick roll is in the delays
I was literally waiting for the codeforces contests from the past 3 to 4 days. Campared to previous months contest frequency has been reduced.By the way thank you for keeping the contest.Hope that all of us perform well in the contest
After a long time :)
Thanks to Supermagzzz and Stepavly for preparing the div.3 contest.
After the last contest when it was showing no contest for near future, it was a little bad feeling but now this contest has filled us with new enthusiasm(mind the spellings).
Hoping for less plagiarism in the contest!
I should prepare myself
Exciting!
Hello everyone its the first div3 of this year and i am here to wish you all good luck for today. Have fun guys.
It is the Second. 1st was #693
Hoping for a great contest.
anyone having difficulties reaching codeforces ?
No, It's working fine for me.
This round has got a crazy number of registrants ~26000, let's hope the round goes smoothly
I already can't visit codeforces.com but I can visit this blog for some reason
I think they postponed the starting time.
Wish the pretest becomes strong.
To all my Indian brothers and sisters Happy Republic Day in Advance. 26th of January is celebrated as Republic Day in India to mark the day when the Constitution of India came into effect. JAI HIND

Congratulations CF on achieving a milestone of 29k participants.

just a normal day in the motherland
Delayed 10 more minutes ?
Could have had my dinner in 25 mins :( Skipped it for contest
I controlled my shit
I skipped exercising today but after seeing ur sacrifice I feel its nothing :/
Instead of delaying they should close the registration lol.
what the fuck is happening ? again delayed :P
I think now the registrations would easily reach to 30,000+ !!
How come again a delay?
Again it's delayed by 10 mins!!!!!
I think that reason of this delay is good skill for getting more and more participants
Again delayed :(
What is going on??
Why delayed again?
Waiting for 30k ?
8:30 ??
It seems it will be delayed until half of the participants go to sleep and we will deal with a normal number of participants.
it got delayed again XD
nice joke, but staff of codeforces is not laughing now
notice again 10 min late
I think they will delay it until 30k people register:)
I think they are waiting for 30k
XD
Why is it delayed?
Why is 30 min delay ?
contest is too much delayed :(
reschedule this contest.
Grrrrrrrrrrrr
common I am not having dinner just because of the contest and it's getting delayed....
More delay but hopefully rated
it's Monday morning I was just trying to get a quick competition in.. now two delays?
Whatshappening?
Delayed again! :(
Contest registrations are increasing by O(1) complexity xD
almost 30 thousand registrants ... that's huge!!
30K lmao....hope to become Expert Today
now starts 10 more minutes late
waiting for 30k
DelayForces !
Close to 30k..!! May all registered participants give the contest.
More 10 Minutes to wait :(
GOT DELAYED AGAIN 10 MIN 300 ppl left to the 30k
why it is going late?
did it just got delayed again? just hope there will be a long queue in the contest. they might be updating pre-test cases due to 29k participants. in order to prevent long queue. (just my guess). good luck to all including (people who made this round.)
What is wrong? Contest has been reschedule twice already :|
Can you reschedule the round again?
Don't extend it again
Is it delayed again by 10 minutes? Now neal's stream timing is out of sync... :C
Just wasted my 30 mins, waiting for the contest to start
watch some youtube?
Or read the comments here . some are really interesting..xD
Not a good sign !!! Hope for the Best
Are you kidding me?
That contest is put off 10min again means I couldn't get at least 4h to sleep in CHN.
Div-3 be like.. wait 10min more..;)
Looks like they want to make some record for the most participation XD..
hope it will start now!!!!!!!!!!!!!
CODEFORCES
Why the contest is delayed?
maybe too much participation in this contest, around 30k participants. Never seen that much before on codeforces.
Atleast tell us the reason for the delay.
I think it's due to the huge number of participants. what do you think?
WoW!
I'm waiting.
wow!
everyone is waiting
Is there any issue with Codeforces server? Content is getting delayed
Now we have record of participants, but I think for another delay we will have antirecord
Now codechef might just get a new excuse XD
what is happening exactly....i thought only was facing the problem.
Its 30 minutes late. Why ?
I have to eat food..
ну иди поешь)
I can relate to this :p
Is it gonna start today???????
..
Lol they might be really waiting for 30k
Cheers to everyone who has participated in the contest with maximum registered participants!
while(participants<30k): delay+=10mins
start_time += 10min
why it is getting delayed
Why is the contest getting delayed??????????? I entered at 8:05pm IST to find out that the contest is starting at 8:20pm IST. When I enter at 8:20pm IST, it is showing delay of further 10 minutes!!
may be some question is wrong
Maybe they're testing if the servers can handle the load
but that is not good idea, delaying also increases number of registrants..
new year resolution effect 30k
There should be an option for unregistration from contest if delays come.
30k participants, This contest is going to be very much fun.
until I see -150 delta.
please no more delay :(
if you not sure can handle the amount of participant, its better to postpone it. don't let another round unrated because long queue..
codeforces randi ,start krrde
You want me to find you on LinkedIn and send this comment to your recruiter? Delete it fast little bitch.
We often get stressed during or even before the contests, which leads to frustration. Keeping that in mind and not to forget the constant delays today i would like to appologise to absolutely nobody, do what u can , the king does what he wants.
Your frustration results in you calling this platform a "whore"? And you're no king. Just a sad pussy behind a keyboard. Don't shit where you eat. If you can't respect the platform then leave. Everybody here is "frustrated" but nobody is using these stupid insults like you.
I will not respect the platform and I'll not leave either. What can u do about it Mr. Authority?
I hope this countdown is not a countdown to the next delay
why this is happening ? does the same happened ever before this ?
Come on!!!! My mom will beat me if i will not eat my dinner at time.
I'm rooting for your mom.
My mom even don't listen to my father.
They're gonna keep delaying the contest until some people unregister because of frustration :D. Don't blame them though, this is a historical milestone.
YES!! yEEEE! 30.000!gogogoGO! yEEEEEEEEEEES!!!!
Me watching contest getting delayed , after waiting for 1 month for div3 -
upload image
*21 days ig
was the delay to hit 30k registrants lol
Now I am 16 years old.
When Contest starts, I will be 116 years old :D.
225 more to go
Lol. Getting into the first 2k just got a LOT harder.
Highest number of participants in Codeforces history.
Damn, approaching 30K participants.
If it takes so much time to reload use m1.codeforces.com , m2.codeforces.com or m3.codeforces.com.
Contest will be delayed for 10 mins. If it doesn't start in 10 minutes just read first sentence again.
Lol!
Congratulations CODEFORCES! 30K Participants!
still, a hundred more to go
Congratulations for having 30K coders today.
Don't delay it anymore.OK?
lag raha aaj Codechef walo ne mil kr Codeforces pr nazar laga diya hai :"/ XD
Is Codeforces aiming for some sort of participation record with these delays? Should have stopped registration on time.
Mike just wants achieve 30k :D
Number of comments increased by 200% due to this delay.
as well as no of downvotes for this blog :(
the delay might be to get 30,000 no of participants
Will it reach 30000 participant? Comment Yes or No Fast..
Yes
looks like it will.
Meanwhile:
What will do neal? Will his stream be delayed?
If you delayed it again , i will quit ok ?
