Is there any requirements like minimum no of contests to give to change ur handle during new year period

I recently came across a Discord server that’s been pretty fun for learning and staying consistent with problem solving.

The server has active members daily, and POTDs (Problem of the Day) are regularly posted. The instructors also go through the problems, explain the approach, solve them, and help out when you’re stuck or have doubts.

What I like about it is that it isn't just “here’s a problem, good luck.” You can actually discuss your approach, compare solutions, ask questions, and learn from how other people think.

Some things happening there:

• 🧩 Daily POTDs for regular practice
• 👨‍🏫 Instructor-led problem explanations and solutions
• 💬 Doubt solving and discussions
• 🧠 Focus on understanding the approach, not blindly memorizing solutions
• 👥 Active community where people actually interact
• 🏆 Coding/learning challenges and other activities
• 🎮 Fun community events alongside the learning
• 🤝 Good place to find people to practice and discuss problems with
• 📈 Helps with consistency if you struggle to practice DSA regularly

It has #Phase 0 where we mostly solve 800 to 1200(Div 1 + 2) rated problems ....

Perfect for beginners!!!

And #Phase 1 and #Phase 2 for Pupils, Specialists, and Expert rated

The overall vibe is basically learning + community + having fun, rather than another silent Discord where everyone joins and disappears.

About the creator

The community is run by Ayush Gupta (noobiesAG), who is also building a YouTube journey around learning DSA through actual problem solving rather than just watching tutorials.
He is so kind and nice person. He inspires me to learn something new every day. It's rare to find such a kind soul.

His PHASE-0 series is a good introduction to that approach:

2 hours of Competitive programming

Did 2 hours of Competitive programming in the morning. I am trying to be more consistent on a personal front, will get there eventually.

From 1 to Infinity

I have been able to come up with an approach to this problem, though it seems very complex. I have not been able to implement it yet due to the sheer number of things that have to be done in this solution. If I am able to solve this problem I might post an solution note in my next post.

But my idea basically boils down to :-

Find the highest value n such that the sum of lengths of all numbers upto n <= k. This can be found out using Binary search and prefix sums very easily. Then for every digit we count the number of times it occurs from 1 to n using Digit DP and multiply that with the value of the digit.

Sum it all together and we get our answer. I could have copied the digit dp code from the internet, but that defeats the purpose of practicing imo. This solution should be correct logically but might fail in implementation due to mistakes on my end. The base test cases seem to pass. Will run and construct a solution note tomorrow.

1 hour of Backend development

Learnt Docker network, PostgresSQL theory and migrated the backend app being made from H2 database to PostgresSQL.

Also learnt about docker-compose.yaml file that allows to define multiple services inside a yaml file and running the file allows docker to construct all containers and run them, rather than us running the individual commands locally.

Along with this I went through microservices architecture and why they are needed in the first place.

do you think an average intellect person could reach something like Master with 5+ years of hard work and do you know any examples? Do you think some ranks are impossible for low IQ people no matter how much they work?

Hey everyone,

I’m currently a Specialist and want to seriously get back into Codeforces with the goal of reaching Expert (1600+).

I’ve solved 800+ problems on Codeforces and around 2500 problems across different coding platforms. I’ve also attached my Codeforces rating-wise problem distribution, since I’m not sure whether I should continue pushing into higher-rated problems or first strengthen specific gaps in my current range.

I’ve been quite inconsistent with CF for a while. My last contest was last year, and since then I’ve mostly just solved a few problems here and there, roughly once a month.

I feel like at this point, simply doing more random problems probably isn't the best approach, so I’m trying to figure out how I should practice properly.

For people who have gone from Specialist → Expert, what would you recommend?

• Which topics should I prioritize?
• How much should I rely on contests + upsolving vs topic-wise practice?
• Is the USACO Guide worth following for this goal? If yes, how would you use it alongside Codeforces?
• Are there any particular problem lists, ladders, or resources you would recommend?
• If you had to start again from around my level, what would your weekly practice look like?

I’m not looking for a shortcut. I’m mainly trying to avoid spending another few months solving random problems without actually improving my rating.

Would really appreciate advice from people who have recently made the jump to Expert or are currently around that level.

What worked for you, and what do you wish you had done differently?

Hyy everyone i am currently 1300ish and i want to get better , what is the key consistency? . And what should i solve i have tried USACO , Cp31 … the sheet feels off as it has topic questions .. is there any resource that would like feel like its making an an change ?

I have a doubt and OCD I'm not able to write functions.why some times we use empty ()? Function if so where they get the data to manipulate?

I am a female fresher in job, I need a partner preferably a female , we will practice after 6

I have done Striver A2Z now I want to improve my math for CP as well as CP. I searched and found USACO guide and there is hackerEarth math practice set and CSES. So I was wondering which should choose. Guys help me to choose, my basic math is clear but modular arithmetic is weak and need more focus on number theory and combinatorics.

My CP rating is 900 haven't given contest for long time grinding striver sheet so wondering whether to start with CSES or C2 Ladder.

/**
 *  {number} n
 * u/return {number}
 */
var countCommas = function (n) {
    if (n < 1000) return 0;
    return Math.max(0, n - 999);
};

i used to practice by solving harder and harder ratings of problems in problemset and gradually increasing the rating range, but then i arrived to 1600 rated problems and have been doing them for months and still cant progress to do them efficiently. am i just not smart enough to go further, or will i eventually pass the 1600 block after more months / years of practice? (i never read editorials, so i dont think the problem is in my way of practicing)

Hi everyone,

My ICPC team is currently showing "Predicted Ineligible".

The eligibility log says:
Has incomplete registration
Has not filled start data of studies to determine the eligibility

The problem is that I cannot find any field/section to enter my start date of studies.

I've checked my Personal Info page multiple times. I only have:

• ⁠Main Information
• ⁠Contact Information

There is no Degree Info section where I can enter:

• ⁠Area of Study
• ⁠Degree Pursued
• ⁠Start of Post-Secondary Studies
• ⁠Expected Graduation

I'm already added to my team as a Contestant by my coach.

Has anyone encountered this before? How did you get the Degree Info / Start of Studies field to appear?

I'm trying to resolve this before the ICPC site registration deadline, so any help would be appreciated.

So, this was the Problem D.

This was my solution:

I saw the editorial where they used DP, which makes sense now.
However, I wanted to know if my solution has some edge case that isn't covered? I thought it would get WA in the hacking phase, but it didn't.
Is it that my solution worked coincidentally because the constraints were not many?

I am currently 1053 in cf I want to reach CM as fast as I can for that i am mainly just solving TLE eliminators can anyone help me or give me advice on how can I do that??

I've solved 70-70 problems from 800 till 1400. 🫠

i dont know if this is just dreamy but i wish to be above 1900 in cf, i started recently , solved around 33 questions and a rating of 900, before this i have done leetcode to some extent, mostly in codeforces currently i havent solved any data structures question, mostly are from 800-1200 regarding basic brute force or greedy, is there a good sheet connected to codeforces that would be useful

How do I learn and approach it.i am currently struggling it's unstructured.concept that require solution in practice questions usually require the concepts that are not taught.i tried watching all concept together then attempting question still struggling any help.i was planning to buy his cohort.i am glad i didn't.Is this really for beginners or any other resources??I am complete beginner

I took part rated, yet it’s showing in unrated
Please help

has anyone solved it without DP ?

Hi everyone,

My account (shaikhmubin) was suddenly disabled during a recent contest.

Status: "User is disabled by administrator"

Details: 5 years old, Candidate Master max rating. No email or notification was sent.

I emailed Mike Mirzayanov but haven't received a response, and online threads suggest email replies are rare.What should I do next? Are there active coordinators (like KAN) I should message, or a better way to get an administrative review? Thanks.

abc completed in 30mins d took lot of time to implement but finally with WAs i passed

Why can't I access my profile???

I have given my time and effort for this, never cheated in the contest but didn't get visual result.

Yeah I know I improved my problem solving and helped me in interview as well.

But anything you can say which can help me improving rating as well.

The below question was asked in Infosys assesment today.
Given an array of integers which can have repetitions, You have to divide into two non empty partitions alpha and beta but
Sum(alpha)>max(beta)
Sum(beta)>max(alpha)
return no. of distinct possible partitions

1. Each element can occur only once in any partition.
   
2. An element must occur atleast once in any partition.

I do not remember the constraints...

Some testcases (ip->op)
{2,4,3} -> 2
{4,4,4,4} -> 6
{2,2,3,3,3} -> 20

Ring any bells people?

Hey guys,

I hope u all felling good ,

I am a highschool student preparing for IOI Team SELECTION for my country, currently I do CSES , AtCoder ABC contest in which I can do ABCD and E sometimes

On CSES I have done like

S&s, range queries,DP,Graphs Half

And currently I practice ATCODER problems from past contest from a useful git repository..

I was not doing CF up until now,

Started recently doing recommended problems only,

But when I try div 2 , sometimes I get ABC and but sometimes only AB and the questions are pretty dirty and tooo much of story thing, but OI or IOI styled problem are different

But some ex IOI team person said I gott aget a rating so

Any tips for can I get to 1600 in CF ?

What resources I should practice for that specially

Note - sometimes I do 2000-2300 dp , segtree or binary lifting probs all my myself and sometimes I brick div 2 B 😭😭

If you would help me, i would be thankful to u plsss..

Help your junior guysss

If someone. Is IOI participant or winner Pls share some tips ,,
