Obviously, Finalists should not watch the stream during the contest. The mirror contest participants can watch it since there's no way to prevent it. This is why the mirror is Unrated and the standings is hidden.

I know, it was a long post and you are tired

Sharing my video of winning* the contest: https://www.youtube.com/watch?v=9Vv2ZukG1CM&t=2476s

(*tourist doesn't count)

The problems were great, but the confusing statements ruined it for me, I really think more attention should be given to making the statement clear and understandable.

For example in problem D it was not clear that k was for the entire problem, when I read it I thought he could not swim a distance more than k in a row which led to me writing a completely different solution and wasted a lot of time on this.

I spent more time understanding the problems than solving them.

I am not saying the contest is bad, but I felt this should be addressed.

Problem D is almost same as https://codeforces.com/contest/1637/problem/H xD..

We are waiting for the AWTF2024 Finalist Profile to be updated!

1. Try to not care about rating and enjoy solving problems.
2. If not possible, do it as a necessary sacrifice for whatever reason you really want to do it.
3. If this does not work, give up. There are much better things in life to worry about. Problem solving is not everything, and doomposting on Codeforces every other day will not solve anything.

something else

Indonesia:

• nathjess — 1st time, 2 attempts left

• Faeee — 1st time, 1 attempt left

This is also our country's 1st time in EGOI 🎉

We are having a network issue and the contest is delayed. We are gonna start when we can, and also announce it here. 1hr delay is tentative, it can start earlier.

It was taken when taking off from the Helsinki airport.

i mentioned this issue in testing, but unfortunately they did not take it into account

I have to say, usually Luogu div1/2 difficulty >> Codeforces div1/2 difficulty. "similar" is a fake information.

I think stories which makes the statement more understandable than formulas are acceptable. But to people including me who do not use English often, these story statements mostly give them huge difficulty to understand what they should do. Sometimes feels like I spent so much effort for a lot of messages which aren't useful for me to solve the problem. I think Atcoder does better on this.

sorry for necroposting but it's the same as this CSES task: https://www.cses.fi/problemset/task/2417

It's intern/placement season in India. Hence, a lot of people have started to resort to cheating here for internet points.

Frankly speaking, you had a flat contest and a bad contest, I'm more surprised that you didn't come here when you had roughly 10 contests of mediocre performances in late 2023.

Now in more seriousness, as others said here, you shouldn't see rating as your only goal, but more like something you will eventually end up achieving.

Learning new things and enjoying the experience are way more important things to strive for than just some numbers on a screen, because these will be the ones which will bring you actual benefits in real life too.

In the picture on the top of the website, why the username is "maroonk"?

The contest will start at 13:45 (in 3 minutes).

1. 10^6 == 1,000,000
2. less than 10^6 is 999,999 which is 6 digits.

Niko-Bellic is right.

Right makes sense, thanks

you are cute

The contest will start at 13:45. Sorry for inconvenience.

Wow a luogu contest announcement on codeforces

He was told this is allowed before posting. He thinks it is funny and posted it anyway.

it is free... (as in, the free version is still good)

really nice contest, I enjoyed the surplus of math-related questions, and it felt fitting for div 3. great job to all the organizers!

I'm more surprised that you didn't come here when you had roughly 10 contests of mediocre performances in late 2023.

He did, he just deletes blogs after ranting about it and getting advice from people (and ignoring said advice).

Was it only for me ,or it was really hard to decode the problems?

Will the mirror contest's standing be released after contest?

Why do they even use unnecessary, useless stories in problem statements? I always want them to provide short, crisp, to the point problem statements.

"gently correcting" is correct, though

Great job, I also needed the video. It lightened my day to see where you started it. Also listening to explanations on E-G.

Fantastic round! E was an amazing problem! Thanks a lot for the round Noobish_Monk ErnKor Kmes ArSarapkin and all testers!

That has been an issue for far longer than 4 months. And yes, it was also widespread before.

I WANT JUSTICE.

My contest submission : 269977715

Same code submission: 270045857

My submission getting runtime error but other submission accepted, this whole thing ruined my contest rating.

Please do something about this.

Recipe?

i got it my mistake

Мужики, это конкретный позор с задачей F. Как можно было не написать 1 уточняющее предложение. Или хотя бы 1 тест объяснить. Для чего вообще вам тестеры нужны? Если вы вот так относитесь к задачам.

Why are names (such as k1o0n) that are difficult to pronounce given in the problem statement? Such names often delay the understanding of the problem statement. Can't understandable names (such as Alice, and Bob) be used instead of such names?

There is nothing wrong with that in my opinion, also I wouldn't really call these problems observation based problems. Programming is just a medium through you solve problems, the emphasis is on the problem solving aspect.

Auto comment: topic has been updated by maroonrk (previous revision, new revision, compare).

Why does it sound like its written by AI. Also you are telling to take the characters which are even in number from each string in the array and take them in the final answer to from a palindrome with taking atmost 1 odd character which we cannot do in the question asked. We are supposed to concatenate the strings to from a palindrome

Beautiful picture. where is this place?

I might have gotten E in contest time itself but cloudflare had other plans.

Oh, I did not know that. Thanks a lot for helping sammyuri.

there is also easier greedy solution using O(1) extra memory: create a variable last_land_point and set it = i whenever you get on the land. Then if ever last_land_point become too far, that is farther than jumping distance, start incrementing a variable for how much to swim. If you hit a crocodile while swimming, not possible. If you have to swim too much, not possible.

Буду знать. Просто видимо как новичок я вообще этого не понял. Я думаю со мной многие согласятся, что после прочтения не понятно в чём вообще состоит проблема. Т.к. не объявлено, что должны быть ТОЛЬКО плохие подотрезки. Только в конце контеста это написали. Этих проблем вообще не должно быть, потому что пишут хотя бы 1 пример, а лучше пару. Чтобы вопросов не было. А так получается, что легкие задачи с примерами, а сложные(до которых Div 3 новички еле еле доползли(Я)) должны понимать, как будто они уже с опытом. Но за Ешку лайк.

a recent trend is to give a constructive problem as div -3,4 E making it confusing wheather to go for e or f

Sorry for misreading the tutorial. Then it's a shorter but less efficient solution lol (but I think mine can also be optimized with the same trick or by using unordered_set

Just follow the instructions on the image. Also, during the hacking phase, you cannot see the hacker's input. If you can't view the tests, this might be the reason.

Here is your test used for hack: Link

set trivializes, only add if its a divisor of x, max 36 elements in the set so it wont tle

bruh i asked chatgpt to solve D with dp and it actually worked

Team India:

• Neha S (Spensa) — 3rd time, 0 attempt left
• Neha S (overwatch) — 2nd time, 1 attempt left
• Aanya G (ag._.) — 1st time, 1 attempt left
• Mansi S (Toast12) — 1st time, 4 attempts left

Neha S will win EGOI 2024.

Even more than half submissions in codeforces are copied.We need to make something like codeforces police to catch out the cheater something which will remove the ai effect then compare and so we can put the cheater tag on the cheaters

I think it's when there are multiple unpronounceable names, and they all begin with the same letter, then they're really difficult to keep track of while reading the problem statement.

Oh sorry, my bad :')

All hail Cheat Patrol, first of its name, but second of its type(after LC Police), the nightmare of cheaters and protector of codeforces.

Div1+Div2=Div3 (just kidding)

Regardless of whether you are a trusted participant of the third division or not, if your rating is less than 1600 (or you are a newcomer/unrated), then the round will be rated for you.

If the rating range is 1600-1900(didn't cross 1900 at any time), then you would only be in the official standings.

Btw, Congrats!! on reaching Expert

see you have 2 states in your dp. Mainly N and K (swims in your case) both can be 2*10^5 so total in worst case is >10^9 Actually you could have taken m because m is less than 10 Anyways u dont need both k and m in and can just do in n space. Check my solution and let me know if u want me to explain

btw my dp finds min number of k needed to get past river and if thats more than k then u cant else can

why would you want chat gpt to solve for you?

D has a very clean DP solution.

Let $$$dp[i]$$$ denote the minimum number of swims required to reach index $$$i$$$. The transitions are -

For $$$j = i + 1 - m$$$ to $$$i$$$

• $$$dp[i + 1] = min(dp[j], dp[i + 1])$$$, if $$$s[j] =$$$ 'L'

$$$dp[i + 1] = min(dp[i] + 1, dp[i + 1)$$$, if $$$s[i] =$$$ 'W'

Finally, the answer is YES if $$$dp[n + 1] \le k$$$.

Yeah, that's true, but I exceeded the memory limit during the contest using dynamic programming, so I used BFS instead. It is also an easy solution.

i tried this interesting problem, although it might be a bit simple for the techniques you are talking about: 1305G - Kuroni and Antihype

UPDATE: CodingPokemon said that these problems are wayyyyyy to easy for your level

I've got a lot of free time lately. If you're interested, feel free to contact me anytime^ _ ^

------- Found a partner for now, but still welcome all kinds of exchanges ^_^

Oh, GPT cheated me, lol

Funded by Telegram & Youtube

It's a pathetic situation to be very honest. There are telegram groups that supply like the first 3-4 problems. Some people widely participate in this cheating process just because they have the notion that the better their codeforces ratings is, the better the job they'll be getting.

Congratulations! Good luck upon reaching expert and beyond!

Smile423man don't be shy, say it

Congratulations Smile423man!!! All the best for your next target.

Yeah, Atcoder does A LOT better on this.

I hope, that it will be useful for you

This means that your goal is unattainable (with your level of knowledge) and it is better for you not to have hopes, but to set an adequate goal.

Me staring at E for 1hr +

Please report this guy. He is sharing answer during the contest time. He is destroying the cp environment. here is the link : https://www.youtube.com/live/frrrP-SHXWA?si=nnX4Ghj0bqvDJEeN

It's funny because I exceeded the memory limit using a DFS solution, and had to think of a DP solution instead.

both the dp and non dp should be O(N*10) solutions right !

Here is another problem, taht uses treap: 4A - Watermelon

LSD and Tool

people are literally live streaming the contest so I think you can now figure out what is happening

that (the editorial) is correct. strictly less than 10^6 means <= 99999 -> max 5 digits :)

the cheaters...

Мансур Мамадахунов — Wansur Оралханов Дінмұхамммед — dimachine

Oh , i didn't see it

Thx : )

I think you just misread they wrote that k is for the entire swim from 1...n

The river is very cold. Therefore, in total (that is, throughout the entire swim from 0 to n+1 )

oh yeah. very weird descriptions. probably their native language is not English.

eh just leave it until you find it interesting again
