three Years Ago, i Published "How Can I Become an Expert?"

In fact, that was a very stupid thing to do.

BigBadBully advised me and said: "If you want to become an expert cyclist, you need to cycle a lot. Don't forget to take breaks."

I replied: "I just wonder why some people downvote even though they were beginners like me in the past, and there is no person who was not a beginner in education. Frankly, I did not expect that someone would downvote. I expected that there would be people encouraging beginners and helping them to progress and develop. I hope you To be more respectful and loving. Thx for reading ;)"

Then he replied to me: "Why don't you just try cycling more? It'll help you develop your cycling skills."

Today, I feel bad because I didn't cycle more.

BigBadBully became an expert, and he was a newbie just like me!!

And I'm still a newbie!!!!!!

So please: If you want to become an expert cyclist, you need to cycle a lot. Don't forget to take breaks

Whenever I close the Codeforces website and then try to open it again, I always face the same annoying problem. The site keeps trying to load for a very long time — up to a full 15 minutes — and I wait in front of the screen without any result.

But the strange thing is, after these long minutes of waiting and patience, everything becomes normal. I can navigate between pages, enter contests, and solve problems at normal speed, as if the long wait never happened.

This problem repeats for me every time I try to enter the site after closing it. And now I have two important questions:

Am I the only one suffering from this problem? Or are there others facing the same long wait?

If the problem happens to more than one person, is it possible for the Codeforces team to solve it? Because it really affects the experience of using the site

and if it is only with me can u help me to solve it?

thx :__:

How i can solve this problem ?


That is very bad :(

Verifying you are human. This may take a few seconds.

this is mistake it takes from me more than 30 minits !

there are a lot of time that i waste it in waiting for Verifying

i want to say for Codeforces Admins pls solve this big problem

i am very angry from it

thx:)

Hello when I try to submit a solution on codeforces i only see:

"verifying you are human. This may take a few seconds."

it is been like this for 2 hours and I can’t submit.

does anyone else have this problem or only me???

and how i can solve it ?? thx for help :)

Sometimes we see a good problem but we do not have an easy way to save it for later.

Now, poeple use bookmarks or notes , but that is not very comfortabl for them

My idea is :

-add a "To Do" button on every problem page.

-add a "To Do list" in the user profile with all saved problems.

-if the problem is solved, it is removed.

Alternative solution : a chrome extension that does the same thing.

Hi Codeforces community!

Please recommend 10 high-quality problems focused on prefix sums.

I want to master this topic and become truly proficient in competitive programming.

I’ll solve all of them tomorrow as a personal challenge. I’m really excited to do this.

Thanks in advance for your suggestions!

Hello Codeforces community,

I hope everyone is doing well! I’m exploring new ways to accelerate my learning in competitive programming, and I’m curious about your experiences and opinions on using large language models—specifically ChatGPT—as a personal coach. Before I commit to integrating it into my routine, I’d love to hear your thoughts on:

Has anyone used ChatGPT to brainstorm problem-solving strategies, generate hints, or review their code?

Did you find its guidance helpful for understanding algorithmic concepts (e.g. DP, flows, data structures), or was it sometimes misleading?

I’m looking forward to hearing honest experiences—both positive and negative. Your feedback will help me set up a healthy, productive workflow that leverages AI assistance without undermining my own growth.

Thank you in advance for sharing your answers!

This is very bad

i want to know what is the test ?

there is not anyway to know that

Codeforces Developer PLS can u help us to do that ?

this will be good for all people

thx....

at input the number of test case is displayed but in output the number of test case is not displayed this is very important when there are 10 Tests for example

i feel am very weak at math this problem take 2 days with me https://mirror.codeforces.com/contest/2117/problem/D I'm not even close to a solution after 2 days.

my question how i can get better at math?

in problem D if https://mirror.codeforces.com/contest/2121/problem/D

N=50

array A is 50 49 48 47 46 .................1

array B is 100 99 98 97.......................

so we need 50*49*2 operation which is greater than 4900>1709

I hope the answers are from youDon't depend on someone else,

I hope the highly rated people will share their methods with us :)

Advise me on anything related to training or development of it!

Hello codeforces community i want to ask about way to become a profissional person in algorithms such as binary search and graphs (DFS,BFS) i learned it but now i want to solve some problems about it .

my question is how i can solve problems about that topic ?

most profissional people said that i should't solve by topic , but i want a way to become profissional on these topics :)

How can I solve blind problems when I want to master a specific topic? I feel a strange contradiction.

I don't think I can solve problems from prblemset and wait until I encounter a problem that requires a specific algorithm. This will take a long time.

Note: -I have an IOI competition next month and I need to master these topics before then.

-I do not think that this is a repeated question or that has existed before. I hope that the community will be more open to beginners like me, and I would also like to remind everyone, without exception, that they have gone through this same stage :_:

i want to ask about time , what the minimum time of every problem should think about it? can i read tutorial after 15 minutes and it is benefit ? I hope the answer comes from personal experience.

i want to ask the high level (rate ) people how are u going to expert ? what are u doing to improve your skill ? what is the References and sheets that i can use it to help me to improve my skills? How can I develop a solving skill after learning a specific algorithm ? pls add anything that maybe help me to become better , thx! Note : I am Practicing lol ;)
