How to use Codeforces [GUIDE] I see a lot of newcomers struggling to use the website to it's fullest, so I decided to write a blog that has all important information about how to use Codeforces in a single place. I will update it with time, so feel free to write your suggestions/questions in case I missed something and I will be glad to add it to the post!
I would like to thank [user:_Vanilla_,2022-02-05] and [user:mesanu,2022-02-05] for helping me write the blog, and [user:Monogon,2022-02-05], [user:down,2022-02-05] and [user:AlperenT,2022-02-05] for proofreading and giving suggestions.

The Reason You are Bad at Codeforces — You are Not Russian Enough If you are triggered by this clickbaity blog title, you are probably interested in improving your Codeforces skills. Now, I will share my point of view on the differences between Codeforces and ICPC contests, and how you can, in my humble opinion, maximize your Codeforces rating gain.
I mostly consider that all conceivable competitive programming problems need three aspects of skill:
1. Observation — the ability to understand the problem and come up with non-trivial properties.
2. Technique — the ability to apply a well-known algorithm or data structure to the problem.
3. Implementation — the ability to code fast and debug fast.
Collaterally, I refer to these three skills as Russian-ness, Chinese-ness and American-ness, respectively, for reasons you will soon see below.
## Observation (Russian-ness)
Observation means that you stare at some problem for a sufficient amount of time and you are able to reduce it to some easier problem. One good proble...

On "is this greedy or DP", forcing and rubber bands #### Introduction
When it comes to "problem-solving techniques", there are roughly 3 levels:
1. Concrete algorithms (Kruskal's algorithm, Li-Chao tree, fast Fourier transform)
2. General patterns (dynamic programming, greedy, square-root decomposition)
3. Meta-strategies ("how do I even go about solving this problem?")
There is some grey area, but in general this classification works well.
[Many tutorials](https://codeforces.com/catalog) have been written about ideas that fall into 1 or 2.
But very little has been written about the third category. On the catalog, I think the
only blogs that really qualify are [this](62730) and [this](20548). There is also
[this](92248?#comment-809401) valuable comment. As to why there is so little written,
I think I can identify two reasons.
- Most strong contestants don't really consciously think about these.

I am a huge fan of CodeForces and specifically CodeForces blog posts! There are tens and hundreds of gems posted on this platform throughout the years. Thankfully, recently there was added the [catalog](https://codeforces.com/catalog) page where a lot of cool articles can be found. Personally, if I want to remember some classical algorithm, I would go to websites like [cp-algorithms](https://cp-algorithms.com/), but CodeForces is the place where new or rare stuff is born, where new points of view emerge. I think it is one of the most valuable functions of this website, and I would like to facilitate its growth.

Improvement suggestions for CF Catalog Firstly, the CF Catalog is a great feature that makes it much easier to learn topics by having a lot of educational content in the same place, so thanks [user:MikeMirzayanov,2023-01-14]!
I was originally going to post this as a comment under the catalog announcement blog, but it became too large for a single comment, and it will probably need some more discussion.
I want to suggest the following improvements for the catalog (and initiate a discussion on how best to tackle these issues with the current version):

For context, I do believe Codeforces is the best website for competitive programming contests at the moment. I sincerely give credit to Mike for creating Codeforces and providing participants and contest authors a platform for interaction completely for free. I am confident that Codeforces is the most appropriate website for being *the* platform for sharing knowledge, exchanging tricks and methods, and collaboration between both contest participants, their authors, and coordinators.

A look at Competitive Programming post-hibernation Hello friends!
As I've recollected in a previous [post](https://codeforces.com/blog/entry/97566), I am an old competitor who hadn't really participated since ~2014, and recently got a bout of nostalgia to return to Competitive Programming. So, I did a couple Topcoder SRMs, suffered through some SNWS rounds, participated in [three regional 5hr competitions](https://contest.yandex.ru/3QF2021) on three consecutive days, and dozed off at every Codeforces contest I tried to wake up for.
A lot of things are still the same as 8 years ago: [user:tourist,2022-01-26] is still at the top, grey coders still ask for how many minutes to solve a problem before reading the editorial, Russian university teams [continue winning](https://icpc.global/worldfinals/results) ACM ICPC, and Snarknews never gives up on his alternate competition formats. But in this post, I want to focus on the new patterns that emerged since my last time around.

How to Effectively Practice CP + Problem Solving Guide This is a slight tweak of [a practice guide](https://www.reddit.com/r/usaco/comments/pk3tjp/the_ultimate_usaco_practice_method/) I wrote a while ago on USACO reddit since I thought it could be helpful to people here. Some USACO specific sections or extra clutter I left out here that aren't needed for a general audience. This should cover all general cp advice I have so I never have to retype.
#Introduction
This is a post on how I believe is the best method to practice modern day competitive programming based on my experiences. I assume you already have some knowledge and know simple things like binary search and dfs/bfs, but **read the footnote if you are complete beginner** (never code, solved <50 problems, div2 A/B too difficult, grey or stuck low pupil).
First, a quick tl;dr of the practice strategy before a bunch of specifics and explanation:

Userscript: table view in Catalog #### Background
When [Catalog](https://codeforces.com/catalog) was first introduced, I asked for a way to sort by blog creation time to be able to check for new blogs. Sadly, this has not been implemented, at least the way I imagined it (there is a time filter though). So, I decided to implement it myself. The result is an userscript.
#### Features
I think the concept is pretty self-explanatory. Some notes:
- You can click on the table headers to sort by a field. By default, we sort descending based on creation time.
- Whether or not you are using the table view is saved in a cookie. If you have turned on table view, it will still be on the next time you visit the page, so you can use it as a "default" if you want to.
- The script is disabled when in management mode because you can't really do management in this view.
- Open source, so you can customize it if you want.
#### Installation

How to un-become Master Since no one asked on how to un-become Master I decided to post one. So, here are the ways I managed to un-become Master after a lot of effort and hard work.
### Have a life
Having a life is the easiest and most efficient way to un-become Master on Codeforces. Relax, play ping-pong
### Get a class
Getting a class is another perfect way to un-become Master. You have way less time to focus on Competitive Programming and way more teme which is perfect for losing rating. In my personal experience, after I got a 10 at a prestigious Paul I started to not care so much about competitive programming because in the end of the day virtual rating on Codeforces is meaningless, but 10 on catalog is eternal.
### Prepare for IIOT
Trying to compose a team for IIOT instantly brings your free time to 0, which might sound tragic but actually is a great thing. You realize there are more important things than virtual points and you start thinking about what people to team up with. A ...

(Plenty of) useful blogs in CodeForces Here are some useful blogs I found in CodeForces.
Note that:
- This list can be treated as an extension of [catalog](https://codeforces.com/catalog), since much of these tutorials are included in catalog but the others are collected by myself.
- The same blog may be included in this post twice or more.
- Blogs to ask questions are **NOT** included in this blog, since they seemed not quite useful to CP.
- If there are any blogs that I have missed, please tell me in the comment section. Thank you very much.

Worsening Codeforces blog qualities? TL;DR: more and more troll blogs, attention seeking rewarded with downvotes, vicious cycle?
Dear Codeforces friends,
Recently there are a lot more joke/troll blogs on the Codeforces platform. Obviously, some amount of jokes to lighten up the mood and create a more relaxing atmosphere is a great idea (for example [user:sus,2022-03-30] has funny trousers prizes jokes), but the situation of trolls appears to be have worsened significantly throughout the past weeks. More and more repetitive content pops up every day, and useful tutorials are often overshadowed by people saying "hurr durr downvote me pls ! ! ! !! here is a funny amogus pic hahahhahhahahaha".
The content posted by trolls varies, but usually falls under a few categories as follows:
1) Random spam / jokes ([user:Polygons,2022-03-30])
2) Deliberate hate speech ([user:Bloodless_Castrator,2022-03-30] before they got banned)
3) Content that makes people uncomfortable ([user:zucyo05,2022-03-30])

First of all, who this article is aimed at.

The Codeforces upvoting mechanism As a lot of us already know, Codeforces has certain differences in how it treats upvotes from users.
There are rating tiers on what your upvote is worth, and it is done to give non-negligible importance to the rare high-quality content that more experienced people can generally perceive quicker than others as useful for the community. For example, sometimes low rated accounts cannot distinguish between useful and useless higher level content, which has the potential to help them as they grow. This also gives people motivation to work harder to get to a better rating, though this is still very debatable. People treat this as ratism, but it is up to you to decide whether this is a good thing or not. It already works well as a spam-reduction measure, though.
However, it also recently started treating upvotes from "contest-inactive" accounts as worthless (i.e., accounts that have not participated in a rated contest for more than 6 months are unable to show that they like/dislike cert...

A Never Seen Before Data Structure -- O(log(n)) Range Queries TLDR: just take [this blog of mine](https://codeforces.com/blog/entry/121381) and sprinkle some [canonical skew-binary numbers](https://codeforces.com/blog/entry/74847) and boom, you have a weird version of the Fenwick tree that is asymptotically faster that the Fenwick tree on an obscure operation.
It also turns out that we can perform point updates without commutativity or inverse operations, which the plain Fenwick tree can't do by itself.
## The idea
I explained on [my previous blog](https://codeforces.com/blog/entry/121381) that we can think of the Fenwick tree as a set of intervals, and that we can use those intervals to answer any range query in $O(\log(N)^{2})$. But there is no real reason to use exactly the same intervals that the Fenwick tree uses. Instead we can try to use some other set of intervals to make things more efficient (at least in an asymptotic sense).
Instead, we use intervals based on the jump pointers described on [that one blog from the catalog](h...

Petition To Change Catalog's Position I think the order: Home, Top, Contests, Gym, Problemset, Groups, Rating, **Catalog**, Edu, API, Calendar, Help
would be more appropriate because of their functionalities. In my opinion, contests and problemset should be more in front because it's the main reason of the website and EDU and Catalog should be next to each other, due to their educational nature.
Another reason I am not very fond of the Catalog's position is because of muscle memory. Me and a lot of people I know keep on mis-clicking the Contests button because of it's previous position in the list.

Petition to swap Catalog and Contests on Bar I'm sure that anybody who's been using codeforces for more than 2 years by now has the ability to click on the contests button in the top bar with his eyes closed. My hand is used to moving the mouse to the exact place, slightly to the right of "Home".
Unfortunately, this has been rearranged with the addition of catalog, and now I must open my eyes when I click contests, and it is of great discomfort to move my mouse slightly more to the right, as opposed to how I have been doing it for the past 2 years.
I'm sure all veterans agree with me and this is a matter of life or death for the website.
Join me in calling on [user:MikeMirzayanov,2022-01-09] to fix this great injustice and return the contests button to its rightful place on the left.

Catalog Subfolder Links or Bookmarks Hello Codeforces,
Recently I am learning topics from Codeforces catalog, which is great and collected many high quality blogs.
But when I want to access some special topic (for eaxample Graphs), I need to scroll down to the very bottom everytime.

Is there any plan to add links for the subfoders, or any way to enable the bookmark?

Ever since the "catalog" link was added to the top menu, I misclick on it every

Feature Request I was looking for the TopCoder semifinals streams on Codeforces, but couldn't find a path to get there(I did not remember who hosted the stream).
Fortunately, I remembered the URL of the page.
Can we please have [Streams tab](https://codeforces.com/streams) in the navigation bar along side Home, Top, Catalog, etc.?

The catalog of past contests I made a program that generates a catalog of past contests.<br>
Here's the catalog.<br>

problem with codeforces according to me Codeforces user interface is bit difficult to understand for a beginner ,as a beginner I can list down some points:-
1. no proper chart or table for rating (as we are not able to find at what rating we get what rank)
2. complex tags (like API EDU GYM CATALOG)

Great resource for string algorithms String matching is a very interesting field, yet it's difficult to find some good documentation. In this link I've found a great catalog of algorithms with its corresponding implementations. Check it out: [http://www-igm.univ-mlv.fr/~lecroq,2013-06-17/string/node1.html](http://www-igm.univ-mlv.fr/~lecroq/string/node1.html)

аппарат изменился Первый <a href="http://degrus.ru/catalog/group1">токарный станок</a> был создан в 650 году. До н.э. Этот аппарат весьма сильно был непохож от сегодняшней версии. До 14 столетия станки выглядели простенько. <br>Только в XIV столетии смогли собрать данные механизмы с ножным приводом. Но вместо педали использовалась палка. Где-то в 1450 году токарный станок был изменен. К токарному механизму была прицеплена педаль и маломощный привод. <br>После коекакой модернизации токарного механизма в 1500 году на нем начали обрабатывать трудные детали. <br>В семнадцатом столетии рабочим стало намного проще создавать предметы, т.к. Механический кусок токарного станка был заменен на очень мощный привод. Затем многие ученые изменяли уже имеющийся механизм или создавали новые.<br>
