Sorry, buddy, didn't know your attention span had a time complexity of O(infinite)

I absolutely HATE people who don't reply with anything

Seriously, are you a Time Limit Exceeded? An infinite loop in the human language compiler? Imagine spending your precious CPU cycles crafting a beautiful explanation, laying out your thoughts with the clarity of a competitive programmer optimizing their bitsets, and you don't even get a response.

Like, excuse me, is your brain currently experiencing buffer overflow? Did you accidentally AND your speaking skills with zero? Maybe if I rephrased this explanation as a Codeforces editorial starring your beloved bitset waifu, you'd suddenly become responsive again. Honestly, next time someone hits me with a "", I'll just reply, "Sorry, buddy, didn't know your attention span had a time complexity of O(infinite)."

Do better.

and prefix sum and basic observation skills too

This is probably the workflow of the people who downvote:

  1. see blog

  2. see comment

  3. made by low rated (newbie, pupil, specialist)

  4. angy

  5. downvote

Don't worry about that guy. He's just a racist.

Its a matter of if you like CP for not.

If you don't enjoy this, then you should find your true interest.

Also, you can try out some other types of "interesting tasks" (if you enjoy CP). that includes but not limited to: interactive problems, communication problems, partial scoring problems, and subtask based problems that appear in OIs.

On cryi dont have ban perms, 9 months ago

bro didn't get the joke

its a tradeoff to reduce cheating so legit people could enjoy codeforces in peace

I am saying that employers shouldn't use codeforces rating blindly as some kind of sacred factor.

Instead, they should interview the person themselves in an environment where cheating isn't possible, maybe in person and use that metric instead of codeforces rating.

bro really said, "skill issue"

The best thing one could do is to do nothing and let it be established that codeforces rating means nothing.

If someone is truly good, then they will perform good in interviews or contests without direct internet access to the whole web, such as contests like ICPC or IOI.

Codeforces rating losing its value would be perfect as then cheaters wouldn't cheat to gain rating anymore, and we can enjoy codeforces in peace

ah yes, you learn binary search before you learn sorting

and you learn bfs — dfs before you learn stl data structures

Clearly, the way to go

these are AI generated suggestions

these accounts are all banned now

does anybody have a collection of communication problems to solve?

That would be good practice for them.

what could be the rating of A2? (if it was in a rated contest)

thanks for the good contest, but I also got cooked

well a 12 hour hacking phase is enough.

We should stop people from hacking solutions during contest; even if they have solved the problem

Think about chess. Not even every human together can beat stockfish or at least secure a draw. But has people stopped playing chess? No, that's because they play chess for the fun of it.

CP is the same; most people do CP for the fun of it. Yes, the invention of AI effects the people who want to get a job by getting a good rank here, not the people who want to have fun by doing CP.
