Hello.
In the meantime, the onsite event has already begun. You can follow the results at the link https://nerc.itmo.ru/archive/2021/standings.html (refrain from viewing if you want to plan to write a mirror and want the conditions as close as possible to the participants in the competition).
There is great news. This year it was possible to get together without any online participation. Teams write from one computer! Good old ICPC.
And I suggest you join the online mirror. It is designed for team participation by those who have passed the qualifying competitions. Ready to try? Use the link: 2021-2022 ICPC, NERC, Northern Eurasia Onsite (Unrated, Online Mirror, ICPC Rules, Teams Preferred).
Good luck!
Hello.
I started processing responses on the form where we collected your TON wallet addresses. Unfortunately, many winners did not complete the form. I contacted some of them in PM and it turned out that this was not intentional.
We are extending the deadline for completing the form until 2022-04-06 23:59:59 (UTC +3). Please, if you want to receive coins, then fill out the form. A valid address looks like a random 48-character string. To register a wallet, follow one of these links: https://tonkeeper.com/ or https://wallet.ton.org/
The form can be filled out at https://codeforces.com/userForm/203c74605996e40f
Coins will be received by those who are at the top-1000. Additionally, those who solved at least one problem in this round will receive 1 coin each. Details can be read at the link.
The form will be processed on April 7th. And in a week after it, we will send out coins. Please do not disturb me or the organizers with questions that are answered in this post.
Also I remind you about TON Smart Challenge contest aimed at contract source code optimization: https://t.me/toncontests/26 It's not too late to connect and try your hand

Hello, Codeforces.
We live in difficult times. And, unfortunately, our community is highly dependent on world events around us. Three years ago, it seemed easy to send a t-shirt anywhere in the world. Now it's a quest with many unknowns. Just a few months ago, it was not difficult to send a reward to the problem writer. But now, we are cut off from the outside world and regulated by multiple new laws.
And here it is very important not to lose, not to break what has already been done. Don't stand still, move forward. I am very glad and grateful to the problem writers and coordinators that in March we managed to hold 10 ratings (we held 9, come to participate in the tenth). Thanks to everyone who took part in the preparation!
And I want to share another great news. Our friends NEAR has come up with the initiative to support the community during this difficult time. We are pleased to announce that the upcoming rounds will be funded by NEAR, which will help with the payment of rewards to problem writers and coordinators. This is a timely and important help. Thanks!
It will be easier and faster for us if the problem writers or coordinators have the opportunity to accept a reward in the form of a cryptocurrency transfer. In this case, we are ready to transfer 25% more and make the transfer much faster. Oh, it's a pity we can't send t-shirts with crypto.
And I remind you that the next round (and Codeforces Round #780 (Div. 3)) is waiting for you) will take place very soon, on Mar/31/2022 17:35 (Moscow time). I hope to see you among the participants.
— Mike
TLTR: If you are in the top-1000 of CodeTON Round 1, then fill out the form by the link https://codeforces.com/userForm/203c74605996e40f. Also, anyone who solved at least one problem in the round can fill out it and get 1 TON airdrop. The deadline is 23:59:59 (UTC +3) 04.04.22.
Hello. Great news from the TON Team. I give them the floor.
Good news everyone!
We decided to celebrate the successful finish of the CodeTON round by airdropping all the people who have solved at least one of the problems (officially, practice and virtual participation don't count) of the CodeTON round. Such participants are eligible for 1 TON airdrop and a memorable NFT. Please do note that such NFT bears only symbolic value and is not entered to have any financial or investment value.
Please submit your TON wallet address via the link https://codeforces.com/userForm/203c74605996e40f if you are eligible for such an airdrop by 23:59:59 (UTC +3) 04.04.22.
Winners are more than welcome to provide organizers with the TON Wallet addresses to claim their prizes.
We also want to invite all of you to try yourself at TON Smart Challenge contest aimed at contract source code optimization: https://t.me/toncontests/26

Thank you for taking your part, hope you enjoyed the round, looking forward to meeting you later!

I can't write for the entire Codeforces, because this community consists of different people and opinions. I will write for myself. I have two children — my sunshine daughter Tanechka and Codeforces. Recently I talked with Tanya and called what is happening a catastrophe, a big evil, and pain. As a child, I was brought up that war is the greatest of tragedies. So I repeat this to my second child. No war! I dream of waking up in a world where people don't hide in bomb shelters. The offensive of the Russian troops is a terrible dream and a nightmare. The government has given the order, and now people are dying, families are being torn apart and cities are being destroyed. Geopolitical ambitions are above all. It would seem that civilization is here it is, but troubled wild times have come again. Ukraine is a sovereign free country, our friends and colleagues are there.
Tomorrow will be the first global round of this year. And we are happy to sum up the results of last season. We announce the results!
We remind you that the global rounds are a joint initiative of XTX and Codeforces. We are happy to announce that they continue into the new year.
We hold 6 such rounds per year. All of them are open to both divisions. At each such round, 50 brand T-shirts were handed out, and we are happy to give T-shirts to all problem authors.
The prizes for the 6-round series are:
The final standings after six rounds (sorted by total points in four best placed rounds):

Hello, Codeforces.
Unfortunately, we have to declare the round unrated.
Absolutely, these are not issues of the side of Codeforces code, but rather it is a hardware issue. Probably, electricity, power unit or something else. This led to unexpected repeated reboots of the server with the database. I hope that we will be able to quickly deal with this.
We apologize to the writers of the round and its participants.
P.S. Please, do not downvote the round announcement: the writers are not to blame for what happened. And in general, this time it is difficult to blame someone. Sometimes hardware fails.
Mike.
But why not!
Many people here seem to know me. Or maybe not quite? I am ready to answer your questions. Ask me anything! I plan to spend no more than 3 hours on answers. Sorry if I can't answer all the questions.
Let's more or less follow the rules from here https://www.reddit.com/r/IAmA/wiki/index
Below is actually a quote from the rules.
The interviewee begins the process by starting a post, describing who they are and what they do. Then commenters from across the internet leave questions and can vote on other questions according to which they would like to see answered.
The interviewee can go through and reply to the questions they find interesting and easily see those questions the internet is dying to have the answer to.
Because the internet is asking the questions, they're going to be a mix of serious and lighthearted, and you'll find yourself sharing all kinds of things you won't find in a normal interview.
Comments will be removed under a few circumstances:
Please, don't attempt to bypass the rules by adding a ? to a nonquestion.
Questions must be directed toward the individual(s) doing the IAMA.
Under our policies, astroturfing is the practice of an individual or group of individuals who plant questions in an IAmA post for a particular purpose. This kind of behavior is forbidden.
UPD 1: Oh, I'm kind of tired of doing this. Please keep asking questions. Tomorrow I will answer again. Don't forget to vote for the most interesting ones. I will not have time to answer everything, I will choose something. Thanks!
UPD 2:
Hi.
Here is the list of top-voted blog posts in 2021. Find something interesting for yourself?
Hey!
Are you celebrating the New Year already? I wish you a Happy New Year. I wish you progress, joy and health.
We decided to show the current progress in the catalog of significant Codeforces posts.
So far, quite a bit has been implemented, but somehow you can already use it! Would you like to see it? Follow the link:
As planned, the catalog will collect and classify interesting and useful posts from Codeforces. Indeed, many useful articles have been written in Codeforces over 12 years (God, already 12 years!).
The catalog will be a kind of Codeforces golden fund in the future.
The catalog is a tree of topics to which posts can be added. We will still work on its functionality, for now there are only basic features. Don't be discouraged if something is not supported, which is very necessary — just let me know!
Any red user can enable directory editing. Remember that it is extremely important to make all changes thoughtfully and carefully. The tree should not become infinite in size. You need to have a sense of proportion when detailing topics. Please add only good, useful articles to the directory. If there is a disagreement on the contents of the catalog, the administration will make the final decision.
Hope this will be helpful. And together we can put together a catalog and keep the catalog up to date.
P.S. Many thanks to KAN who helped a lot with suggestions and catalog initial content.
Hello.
Here's a small improvement for posts and comments. Likes can now be specified in their markup. Maybe this will be useful for organizing some kind of polls or collecting feedback.
Here are some examples:
Yes, I know that this feature can be improved. I would prefer that we try to use it a little and understand what exactly is missing the most. Maybe we need to implement the fully functional polls.
Let's do a small survey using the new feature.
What is your age range?
Tabs or spaces?
Have you had covid??
Lately, there have been a lot of meaningless blogs on Codeforces. Is it worth strengthening measures to fight against them?
Hello Codeforces!
Oh yes, 2021 ends! I recently realized that 2022 is pronounced like "2020 too". Not that. I want a completely different year!
Anyway, we did a nice job this year. I hope we have pleased you with interesting problems. Thanks to the round coordinators and writers! You make our community richer. Please make us happy in 2022!
I wish you all interesting tasks and brilliant solutions! I wish you error-free code and wish us only rated rounds :-)
Hello, 2022!
And we have traditional gifts!
Hurry! Only until the 10th of January, you can change your handle (but only once)! Note that it will be possible to roll back the changes or change the handle again only after a year. Be careful what you wish for.
You can change your handle to the new one which wasn't used before by anybody or which was used by you before. The links to a profile page with an old handle would automatically redirect to the actual profile.
Again, this year if you took part in at least 10 rounds you can request a handle of an inactive participant. It means that the participant should have a period of activity on Codeforces of at most 180 days, this period should be in 2019 or earlier. The inactive participant can't have posted comments, messages, and so on. It can't take part in more than 2 contests. It will be automatically renamed and informed by email. A user has the opportunity to request back his/her handle: in this case, we will roll back the change and return your previous handle to you. If you can't change your handle to another, it means that some requirements don't meet. Please do not ask me to do something with it. Especially, I do not like requests like "this is my second account, I took an interesting handle myself". I'm not Santa Claus.
Talking about handles I always
reminisce the following story. Once a user wrote me the message: "Please change my handle from I_love_Valya to I_love_Sveta, as I no longer love Valya ..."
The traditional magical tab has appeared in the profile setting. Happy New Year!
In 2021 (as in 2019 and 2020), with the support of XTX Markets, 6 rounds of the new Codeforces Global Rounds are held: common rounds for both divisions of 7–9 problems each. The duration of the rounds is 2-3 hours, depending on the number and complexity of the problems. All such rounds are rated for all participants. At each such round, 50 brand T-shirts are handed out, and we are happy to give T-shirts to all problem authors.
The prizes for the 6-round series in 2021:
Current standings after five rounds (sorted by total points in four best placed rounds):

Hello, Codeforces.
Please, welcome c++20 support on Codeforces. Yes, it is 64-bit. Thanks to Brecht Sanders: I used his distribution GCC-11.2.0-64 from https://winlibs.com/.
If you have installed PBOX, you can add this compiler with the line pbox install gcc11-64-winlibs
. Probably, a good idea is to add C:\Programs\gcc11-64-winlibs\bin
into the PATH. More about PBOX you can read here.
I use the compilation command line similar to other GCC installations: g++ -Wall -Wextra -Wconversion -static -DONLINE_JUDGE -Wl,--stack=268435456 -O2 -std=c++20 <source>
. The only differences are -std=c++20
and -Wall -Wextra -Wconversion
(I plan to use somehow such warnings in Polygon to suggest fixes in uploaded files).
Now you can use c++20 in your solutions. I'm not sure there are many features useful in competitive programming. Probably, I'm wrong. For example, now you can write vector v{vector{1, 2}};
instead of vector<vector<int>> v{vector<int>{1, 2}};
. What else is useful? Please, if you are good with modern C++ then write.
You might be interested in looking at such a table. Before implementation, I always test every C++ distribution for the efficiency of reading and writing large amounts of data. For example, the latest GCC compiler from MSYS2 is terribly slow in some cases. I don't want to use it here. Also, it happens that some specifiers like lld
or Lf
work unexpectedly. In the table by reference, the second line is the added compiler. The columns correspond to different tests. The cell contains the time of the test execution. If I have time, I will someday publish scripts for testing c++ compiler installations.
Bye for now,

Hey! I'm happy to report that Pypy3 is supported. Please test that it works as expected. Thanks!
P.S. I remember about GCC 11, it is in the progress. See you soon.
Hello.
Sorry for it. Actually, right now I don't have any idea why testing is so slow now. Obviously, it doesn't work as expected. It is not because of problems. So please don't blame writers or coordinators. I'm investigating the reason, but don't see it now.
I myself am very upset and I apologize to the authors, coordinator, and participants. I will do my best to find the cause and fix it. Surprisingly, we haven't made any big changes to this part of the system lately. But something went wrong.
Mike.
Hello Codeforces!
I am in the process of making improvements and updates to the judgment machines. I've read the post https://codeforces.com/blog/entry/94587 and I think, maybe it is a good idea to make such a compilation line -O3 -funroll-loops -march=native -mtune=native
? I haven't done any research that it is definitely better than -O2
and it is best in the general case for CP solutions. In a way, this will only strengthen the gap from Python/PyPy/Java, on the other hand: in pragmas and so you can set up everything. What do you think? What are suggestions to the command line?
P.S. You got it right. Yes, gcc11 std=c++20
, pypy3 64-bit
and more are coming.
Hello, Codeforces.
We want to run a series of load testing in the production environment for running contests. For this reason, Codeforces Round 739 will be temporarily extended (in order to test it at the current round). We will temporarily disable the ability to send solutions to it so that its extended duration will not affect the results. After the completion of the work, the duration of the round will be returned.
Our current plan is to finish today.
Mike
Hey!
As I don't see the post discussing the round, I decided to write this.
I do not participate much in contests now. But I love Code Jam. Thanks to problem writers and organizers!
It seemed to me that this round was no more difficult than the previous one. How do you like it?
I liked the problems:
1
is the position of $$$n$$$, so we can divide sequence with this position on two parts and use DP to calculate the answer (don't forget to multiply on binomial coefficient);Hi Codeforces!
Yes, I know it's already April. Time flies so fast lately! Exactly a year ago we were just learning all the "delights" of lockdown.
So let's remember this 2020! What was it like? I don't know about you, but we had a hell of a lot of work.
I will now show you some graphs and you will be very surprised. Lockdown effect? Of course, but we did our best too.
Many thanks to everyone who did not stand aside! In 2020, we celebrated our 10th anniversary and crowdfunding money helps us grow and move forward. You helped us and each other. Thank you. Thank you for your contribution!
We've been working hard all year to make this community a better place. Did it work out? It's up to you to judge. Many thanks to everyone who invested time and effort:
Time to take stock of 2020.
We are pleased to hold programming competitions with companies or for companies. I'm sure this is a great way to support the community of young programmers and hire talented candidates. Here is a list of our main partners this year:
Hello, Codeforces!
I understand that 2021 has been going on for a long time, but here I have picked up a subset of some of the improvements that the Codeforces team made in 2020. Soon I will publish numbers (no, charts) with statistics for 2020. In the meantime, I bring to your attention a list of changes and improvements.
By the way, this is a decent list. This is about half to a quarter of all changes. It's just that other changes are more often somewhere in the internals of the system and are not visible to users. Please read this list. Each item is the effort of someone from the team. Thanks to geranazavr555, kuviman and cannor147 for their efforts. You've made our platform better! Well, by the way, I don't quit programming and many improvements were made by me.
The items on the list are written in a concise and informal form, many of the items I just copied from commit messages from git. If you want more details — ask in the comments, we will tell you! Of course, I forgot to include some improvements in the list.
Hello Codeforces!
This unusual and difficult 2020 has come to an end! What will the new year be like? I wish all of us that we have the opportunity to meet in person so that the contests take place not only online. I ask you to think of something important and good. Let this wish come true!
We have had a large number of rounds this year. I hope we have pleased you with interesting problems. Thanks to the round coordinators and writers! You make our community richer. Please make us happy in 2021!
I wish the participants victories over yourself (and over problems!) and development of your skills, interest and curiosity!
Hello, 2021!
And we have traditional gifts!
Hurry! Only until the 10th of January, you can change your handle (but only once)! Note that it will be possible to roll back the changes or change the handle again only after a year. Be careful what you wish for.
You can change your handle to the new one which wasn't used before by anybody or which was used by you before. The links to a profile page with an old handle would automatically redirect to the actual profile.
Again, this year if you took part in at least 10 rounds you can request a handle of an inactive participant. It means that the participant should have a period of activity on Codeforces of at most 180 days, this period should be in 2017 or earlier. The inactive participant can't have posted comments, messages and so on. It can't take part in more than 2 contests. It will be automatically renamed and informed by email. A user has the opportunity to request back his/her handle: in this case, we will roll back the change and return your previous handle to you. If you can't change your handle to another, it means that some requirement doesn't meet. Please do not ask me to do something with it. Especially, I do not like requests like "this is my second account, I took an interesting handle myself". I'm not Santa Claus.
Talking about handles I always
reminisce the following story. Once a user wrote me the message: "Please change my handle from I_love_Valya to I_love_Sveta, as I no longer love Valya ..."
The traditional magical tab has appeared in the profile setting. Happy New Year!
