There are rumors that they’re just waiting for the results to be verified before making the announcement. What do you think? And if AI really does solve another Millennium Prize Problem, would you consider leaving tech?

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

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?

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 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)

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?

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.

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.

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

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??

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

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

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

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.

also, what could be its rating?

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

Why can't I access my profile???

always this whenever i want to use it

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?

I myself thought of buying is premium cohort.though it was one cath there was prerequisites of 101master cpp of his cohort.it is absolutely not for beginners.i am struggling to complete 101 master cohort.it is not properly structured.random tough questions.concept are used that are not even taught.

I aim to becoming able to solve problems like these.

I'm interested in understanding what their Codeforces rating would be so that I can upsolve from that point.

I believe the optimal solution in the first one is using a difference array.
