I have gotten so many hacks ? My rating dropping so fast because of that. I don't know who is hacking my solutions, if you are reading this, stop hacking me, get a life.

Thanks!

I do leetcode daily, but my leetcode rating is 1350. My codeforces rating is 984, it should atleast be 1200+ in the range of pupil. i dont know why what is wrong with me.

please help;

StellarSpecter has multiple personalities

Why do we have 2 contests in one day, why can't we have normal time intervals between contests.

Please Mike work on it, it's not that hard to do.

We can easily have one contest each 3-4 days, but currently we have two contests either on same or consecutive days and then no contests for a week.

Please fix it.

Thanks

do better next time, everything is not about maths always.

Felt like a codechef contest , will have to think twice before giving a contest authored by you guys.

Go watch

Because of chat GPT and cheating, do contest authors think that making a contest is useless and not worth anymore ?

There are no contests in the remaining month (except unrated trash kotlin heroes).

I request Mike to make more contests by himself, I can offer my help for free to make 1200 problems.

Do not let cf die.

I request MikeMirzayanov to ban all such users.

I would like to request higher rated users to report the sus submissions.

E.g AryanDLuffy solved E1 with chat GPT, his code says it all.

There are many cheaters in today's contest, I can not report such users but If you can then please do so.

Thanks!

The next contest is on 14th september and after that no contest till 30 september (only kotlin heroes), I want more contests.

UPDATE: We have another Div2 on 20th !!!

Hoping to see more.

The next contest is on 14th september and after that no contest till 30 september (only kotlin heroes), I want more contests.

Whole month and no contest ??? please i will die without contests. I cant survive of codechef ewww sorry

The next contest is on 14th september, I want more Div2s.

14th september is too long, please i will die without contests. I cant survive of codechef ewww sorry

Why are you implementing new features on this website MikeMirzayanov when it can not even handle 40k people, even leetcode does better than that.

Come one MikeMirzayanov, you can do better than that. This is not something new, please make codeforces worthy and make it able to handle its users properly.

I believe there are thousands of extremely frustrated users like me who are annoyed because of this.

Such a shame and pity.

2008H - Тест Сакурако

Editorial says Let's fix one x and try to solve this task for it.

okay makes our time complexity q*(something), moving on...

How to find number of i that ai mod x ≤ m for some m

We can use binary search of some sort, making our complexity

q*log(x)*checkerForM, how in the world is this complexity not TLE

Can anyone explain it to me.

The next contest is on 14th september, I want more Div2s.

14th september is too long, please i will die without contests. I cant survive of codechef ewww sorry

I am doing ABC in div2 consistently, sometimes i can do till D/E depends on situation.

Can I reach expert if I keep doing this or what change in plan do I need to adapt ?

Any guidance would be helpful.

I am very good at linking old stuff to a newer problem (thats why I like problem making too). If I have solved say 10 tough problems and you give me a problem thats twice as tough as them but is similar in some aspect to some of them I am most likely able to solve it. But since memory is limited as I practice, I want to keep standard problem ideas in my mind only, around 50 problems for each data structure and 300-400 problems in total. (I will obviously solve more problems but will keep on discarding the problems which I will find similar to my existing knowledge).

PS: I'm someone who doesn't need to solve a ton of problems to get better, I need to solve a particular idea only once and Im pretty sure I would be able to solve a ~40% similar to that kind of problem. So I don't want to spend my time solving more and more problems.

What is the best source for such problems is it CSES problem set, TLE Eliminators, or something else ?

Any help would be appreciated.
