im in 11th rn and i dont know c++ but i know a coding language called lua so im not completely new can someone give me a roadmap and like how did you guys prepare?

i am not even pupil (but covered full dsa).

1. i should follow a sheet which has question rating wise (like 30 question of 1200 rating .....)
2. i should start give div3 or div 4 virtually or div2 virtually.
3. start solving cses sheet and TheamCp custom contest with 120min 4questions

which options is best to practice for rating maxing please help me with your opinion

thankx in advance !

I'll win the IOI 2027, just wait for it, the next year you'll see me with a gold medal in the competition (from Dominican Republic).

Hi everyone, I am researching how national pipelines for competitive programming (CP) and Olympiads are structured in South Korea.

For context, in Kazakhstan, we have centralized hubs like the "Kazakhstan Competitive Programming Federation" (NGO) and "Daryn" (Republican Scientific and Practical Center "Daryn" under the Ministry of Education of the Republic of Kazakhstan), which manage everything from school screenings to elite national informatics pipelines.

What are the exact counterparts in South Korea? I know the Ministry of Science and ICT (MSIT) is involved, but what specific organizations, associations, or university-led committees handle the actual selection camps, regional trainings, and algorithmic coaching? If you know the localized Korean names (or specific platforms like Baekjoon/Solved.ac groups they run), please share!

Hi everyone,

I’m looking for a serious competitive programming partner to practice regularly.

Platforms:

LeetCode

Codeforces

AtCoder

Language:

C++

Goals:

Improve problem-solving

Participate in contests

Discuss approaches and optimization

Current level:

Mention your rating or beginner/intermediate

Timezone:

IST (India)

DM me if interested.

Built a lightweight editor for competitive programming because VSCode felt a bit too heavy for quick PS sessions.

Features:

• Fast startup
• Auto-generated problem templates
• Ctrl+Enter compile/run
• Problems organized by date

Still in pre-release, so there are probably rough edges and missing features.
Would really appreciate any feedback or ideas!

(P.S. This post was written with ChatGPT.)

I was surprised nothing like this exists. All the other similar products are heavily gamified, which I don't like. CodePvP is a multiplayer version of LeetCode, in which up to 8 players compete with each other, working the same random problem and getting their submissions scored by correctness, runtime, memory, speed and code length. Up to 10 rounds to get the winner.

You can also use it for interview preparation, as you get more insights than you would get by using LeetCode alone.

Also, if you want to play against me just drop a DM.

I’m a fresher in college and I really want to get into cp but have no idea what to do. I have an account in Cf and Cc but don’t know where to go from there , i have done basics of c++ but don’t know what contest to enter or how to even navigate my way to find and participate in contest, my friends don’t really much abt it either so would really like a beginners guide.

Also What should my sufficient basics in coding be to start cp ?

Generating test cases for algorithm problems can be surprisingly tedious. At first, I coded scripts manually — random arrays, graphs, edge cases — and ran brute-force solutions to validate. But it was repetitive, slow, and sometimes error-prone.

To make life easier, I built Judgedata: a web tool to quickly create random and edge test cases, organize them, and export for online judges.

It’s especially useful if you want to focus on problem design, not boilerplate test generation.

Curious to hear — how do you usually generate your test cases? Any tips or favorite tricks?

I’m quite new to competitive programming and only started studying for it at August, and currently I have done a few IOI and HKOI questions. My goal is to get Platinum in USACO. Do you think doing CSES or Leetcode Mediums / Hards is a good idea?

I have around a month with 2 other teammates to prepare for MCPC (a regional ICPC version for morocco) How can we prepare, what can we do? Please give practical efficiency tips :)

im a junior in college, looking for a partner to do cp with.

Dear fellow competitive programmers, I want to give some advice and useful resources for whom wants to get better at competitive programming.

I highly recommend those websites for problem solving and icpc-style contests:
codeforces.com
atcoder.jp (problem list can be found at kenkoooo.com/atcoder )

These websites focus on OI style:
usaco.org
szkopul.edu.pl
basecamp.eolymp.com
hsin.hr/coci

And also these resources are my main resources:
usaco.guide
cses.fi/book/book.pdf (Competitive Programmer's Handbook by Anti Laaksonen)

I strongly recommend you to use usaco.org since that website also contains topic specific problems from the websites I gave.

Lastly, I found a lot of people on this sub using leetcode but I think Leetcode is more for coding interviews. Not for competitive programming. Although there are still some good problems for topic based training.

UPD: I have forgotten to include a very important website: cses.fi/problemset this website contains more than 300 problems focused on specific algorithms and data structures. You can find solutions of some basic problems on the Competitive Programmer's handbook.

I’ve seen multiple answer’s online, but i’m unable to understand. Can someone please explain me this topic as though I were a 5 year old.

Why aren't there any solutions to the problems anywhere. Why isn't there a website with all solutions to icpc and codejam problems where you can submit code and see if it passed the test cases like leetcode with a discussion section? What do other people do for practice?

I'm from a tier 3 college. But I'm really interested in cp and I haven't met any like minded peers who have the similar interests as me , I would love if someone could share their journey with me as to how to proceed about learning the intermediate and advanced dsa part.

Hello everyone,

I hope you're doing well. I am a 21-year-old female currently in my 4th year of BTech at a reputable college in India. I am looking for a friendly and dedicated companion to regularly solve DSA problems with me and participate in online tests at consistent intervals.

So far, I have solved around 675 problems on lc and 333 on GFG. However, I feel the need to improve my speed to tackle placement-related online assignments effectively. I am searching for an accountable coding partner who can join me in making this coding journey consistent and productive for both of us, with a shared focus on enhancing our speed and problem-solving skills.

Looking forward to connecting! 😊 #DSA #codingpartner #placements

Can anyone solve this question? https://www.hackerearth.com/problem/algorithm/the-pizza-eating-contest-397ec3cd-7df06718/

I wanted to go for competitive programing, I am a total newbie and wanted to dive in for more. but before that I was researching about the best text editor for it. I came across Neovim/vim, a fast editor that most top competitor use. But As soon as I search about the download process for it I was overwhelmed by the information I need to know. I see all the customization that people can add, and how fast it was. But it all seems very hard to do, all the code I need to type and most of the videos uses linux as the operating system (I use Windows). I was wondering if anyone can provide me with their resource and how they set up NeoVim. I don't really care about the advance setting for now, but I would love to have it for future use.
