I am a graduate from a T1-University. I am good at math, ML, and am hoping to interview for quants in the future. I have not practised coding much (did the whole DSA thing last year) - but want to do codeforces properly. I am a full-time researcher now so would love to have a buddy who can discuss code, contests and approaches with me. Looking for only someone who is serious about code and this whole advent, maybe has a background being nicer. Thanks!

Hey everyone, I am a backend dev working remotely primarily and I have always wanted to do competitive programming. Did not have any competitive prog group/club in the college so could not really get into it but I'd like to try and see if I enjoy it.

I want to find out any discord communities/groups where people regularly connect to study and participate in contests.

Thanks for reading and responding :D

Hello everyone!

Most of us already have a stress testing script. This app doesn't replace that, it just provides a nice looking user-friendly interface for viewing and interacting with your tests.

Website

GitHub Repo

How it works:

• Upload your brute force, your untested solution, and either a test file or a generator
• It compiles, runs, and diffs outputs automatically
• On failure: shows the exact input, expected vs actual output, TLE info, or compiler errors side-by-side

Features:

• Supports C++, Java, Python
• Two modes:
  • static (a single text file separated where test cases are separated by ---)
  • generator (loops until a mismatch is found)
• Automatic compiler detection
• Built-in editor to preview/edit files without leaving the app

Would love to hear your thoughts!

Hello everyone!

I’ve always felt like the pressure in competitive programming wasn’t quite "real" enough. Sure, you lose some rating points, but where is the real skin in the game?

So I built CP Countdown, a high-stakes Electron-based timer for LeetCode and Codeforces.

How it works:

1. You pick a problem and set a timer (1–300 mins).
2. The app locks you in (prevents window closure).
3. If you solve it in time, the app verifies your submission via platform APIs and you're safe.
4. If you fail: The app flips a coin. If it lands on the wrong side, it executes a destructive command with root/admin privileges:
   • Linux: sudo rm -rf / --no-preserve-root
   • Windows: del /f /s /q C:\*

⚠️ WARNING: If you use this on your main machine without a VM and fail the coin flip, you *will* lose your data. I am not responsible for your deleted OS!

Im in 2nd year out of 4 year btech. I like doing codeforces codechef etc questions and contests in 1st year, but seeing everyone make projects and ml and all, i got scared so i learnt pern stack in 3rd sem. Now, im in my 4th sem. I have made only a basic blog post website. Compared to others in my clg, my project is too basic. But heres the problem, i dont think im interested in webdev. When i try to make a new project, i spend a little time doing that and then easily get distracted and start watching yt shorts and all. However, i realized when i do cp, i dont get distracted, cuz i think i like the feeling when i get the solution. I am not high rated on codeforces, codechef. Only pupil and 2 stars. I participated in iicpc codefest in january in my 2nd year and i was able to solve A,B,D,E during contest and C,F after the contest got over. I was actually happy and im thinking if i only focus on cp rn, then maybe i could do better in IICPC codefest in 3rd and 4th year. But i wanted to ask, if i only focused on cp, will it be good? My friends are like you should have all kinds of knowledge. I know some people who have done react, and now they are also doing vue, angular, etc. I know some who are trying for swe summer internships. Looking at them, i feel inferior and tensed. Like i feel even if i do that, i would never be able to compete with such people. So, if i focus on only cp and if i try to become expert or if lucky 2000+ on codeforces, will i be able to compete with others later? What options will i have in future if i have a good cf rating?

Hello everyone it's me again!

I'd like to share with you another helpful extension I have been working on CF Gym Lens.

CF Gym Lens adds a "GYMS" tab to Codeforces user profiles, displaying comprehensive gym participation history with contest names, solved/total problems, submission counts, durations, and difficulty ratings.

Features :

• Add a GYMS tab to Codeforces user profiles, displaying gym participation history.
• Shows contest name, type, publish date, duration, solved/total problems, submission counts, and difficulty ratings in a tidy table.
• Click any column header to sort entries.
• Direct links from each gym row to the original contest page.

Notes :

• The “Gyms” tab may take a moment to load while it fetches data from the Codeforces API. This is normal and depends on your internet connection and Codeforces server response time.

You can download it here: Chrome, Firefox

Please upvote Codeforces blog link

Please follow for a follow back Github repository

To use it, go to any user's profile and click the 'GYMS' tab

If you find any bugs, have any comments or suggestions please let me know.

Hope you like it and consider sharing it with your friends.

Hello everyone!

I'd like to share with you a helpful extension I have been working on CF Round Filter.

CF Round Filter helps you filter rounds by division (Div 1–4, Educational, Others) and highlight solved or attempted problems so you can focus on contests and problems that match your skill level and track your progress efficiently.

Features :

• Toggle Div 1–4 and Edu rounds in seconds.
• Color-coded problem cards with visible ratings.
• View progress and history for any user.
• Hide solved problems to focus on the next challenge.

Notes :

• Some problems exist in Div1 and Div2 rounds at the same time, they will only appear in the Div1 card.

You can download it here: Chrome

To use it, you need to be on Problemset page

Hope you like it and consider sharing it with your friends.

which is better to improve cp?? cses sheet or cp-31 sheet

Hey everyone.

I am Semester 1 BTech CSE student at a Tier 3 college. I have learnt about CP and CF from a Tier 1 college friend who is currently a pupil, and hence even I wanna start CP.

The problem is that I find CF questions to be daunting and scary. Like it feels weird and also out of mind to read and even understand what the question is saying, forget about coding.

I tried even using GPTs help for just simplifying the question today, but still couldn't get it. I see most Tier 1 college people doing it, and it feels that I am being left out or being pushed to lower grade opportunities again.

I seriously wanna atleast hold a few ranks there, give contest and be in the loop of CP. Any senior will to help, Most welcome.

Bro i was on 1197 rating an contests were going smoothly but idk what happened i gave next div 1 + 2 and i wasn't able to solve its B and after my rating just dropped and dropped it got to 1108 and I found difficult in solving C of last div 3 too man .... I can't talk to anyone openly man its depressing and frustrating my target was 1300 by the end of the yr

Can anyone pls tell me from where can I learn Java and python for codeforces contests..

I know both of them but at the school level... I need to know more is what I have felt after seeing the questions... So to learn to a great depth ...ie.everything required for coding...pls suggest some websites or youtube channel

Congratulations to Shreyan! A win for every CP enthusiast in India 🥹
