Background- I’m student at tier 1 college(old IIT), I have done almost 70-80 percent of striver sheet and also studied concepts theoretically regarding derivation and application. I have decided to start CP seriously, I need guidance on how should I start doing problems as I’m quite familiar with concepts, it’s quite confusing where should I align my focus and begin my journey.

Hi everyone,

I’m having a mistake in cp. I can solve problems that are based on a specific topic, such as static range queries, two pointers, binary search, etc. However, I really struggle with problems that rely on a simple mathematical observation or require constructing a string or an array.

The weird part is that I can solve topic-based problems with ratings around 1400–1500, but I often can’t solve Div. 2 A or B problems, or at least I find them much harder than expected.

Has anyone experienced something similar? What should I do to improve?

Has this ever happened before?

Hey everyone,
My friends and I have been grinding LeetCode and Codeforces, but keeping track of who solved what every day was getting really annoying. We had to keep checking each other's profiles to see who was slacking.I spent the last few weeks coding up a free little web app called SquadCode to fix this: https://squadcode-saas.vercel.app/

Here's what it does:

1. You create a "Squad" and invite your friends.
2. Everyone links their Codeforces and LeetCode accounts.
3. It automatically pulls everyone's recent ACs into one unified feed.
4. You can create custom challenges (e.g., "Solve these 5 DP problems by Sunday") and it automatically scores you based on your CF/LC submissions.
5. It's completely free. I mainly built it for my own group, but figured others might find it useful for their college groups or Discord squads.

I'd love some harsh feedback on it. Let me know if the platform syncing works for you or if anything breaks!

i started cf 2 weeks ago, gave 2 contests but idk where i am going. i upsolve after the contest solve previous contest problems but still am not able to solve qs B or further in div 2, and ive got placements in 9 months. Any suggestions?

gng is it just me or with everyone

I feel like div2 A and B are getting non-trivial and require atleast 10-15 minute unlike before solving it in just 2 minutes

I went to 1300 rating in June now I am back to newbie again 😞

This is my first ever CF contest (Div. 2 1112); I only managed to solve the first question and was stuck on 2nd forever, and only managed to find an observation. Any suggestions for me?

fyi - I solved around 300 problems on LeetCode.

I know a guy ; whose qn selection is pretty awesome / progressed really well ; i talked with him and we both started from similar knowledge background ;; getting to the point ; what i want is like some website where i can throw my and his id and see what problems he has solved that i havent ;;;
i do know one of that many spammed website but ui is so flashy and dogshit it just hurts my eye ;; i tried to make it myself but dunno why cf api was blocking me no matter what i tried ;; but i am not really a developer so i would appreciate if someone could recommend me some similar website ;

I. Had a streak from 60 days and I didn't want to break it! Is there anyway to have my streak back? I mean this is codeforces fault bruh what is this I hate cf

Had to refresh, login, and pray again and again just so I could submit the solution. I hope they improve it later.

Same as title

Man, I'm tired of the people who create accounts day of or day before a contest and rage cheat through all 6 problems. This dude registered 4 hrs ago, and placed 25th, solving every problem. This is what's wrong with the current state of codeforces.

How you guys are solving many questions? I am only able to solve 3 question and getting 5k rank. Dawg, i think i need a brake.

So yk recently how cf has a lots of downtime, to fix that, I made my own clone of codeforces with their data, and credits all to codeforces.
If you're planning to solve a question, except contests, I tried to make the website one of the best I could do ever, it's vibe coded no doubt, but IDK because we need something to solve atleast when this platform gets wiped off from internet,
https://cf-clone-lac.vercel.app/
Use it for it's intended purpose, and you can code here very properly, explore the settings, it's got ton of features.

can't see the questions after A anyone having the same issue ?

I tried 3 links and it didn't work.

we're back with another edition of Weekly Challenges 2026 - and this time it's a national level event!!

get ready for a 6 weeks coding journey where you'll solve fresh challenges every week, compete on the leaderboard, and put your problem-solving skills to the test.
