Super Grand Master.

University of Asia Pacific — Bangladesh ( Peregrine_Falcon, xodeChemist, newbie4ever )

After seeing this post, started watching this movie! After a few minutes, I was like — WTF! By the way, the movie was a good one!!

To be clear, this post is a response to this nonsense.
Very well said! I have seen the news about Russians are protesting! But maybe thousands got arrested.

Added, thank you.

Updated. Thank You.

I am doing this. But it's hard to keep up.
There are personal life issues that need to be solved.
There are peoples who deserve my time.
But I keep trying to solving problems whenever I can. You can see my profile below. Practice is significantly decreased. I've started my job as an iOS developer in September 2020. Since then my problem-solving rate has decreased.
But after starting my job I've spent some time setting problems in Toph.co. So,
I can say that you can continue solving problems after starting your job. It'll depend on you how much effort you can give.

The problem statements should rather be considered as riddles.

I am a noob CS: GO, player.

Sorry, I was a bit busy. It can be solved with or without reversing the edges. Just need to change the order of bfs. When problems come to DAG, I usually use reverse edges, it helps in many problems.

Sorry for the inconvenience. Editorials for A, B, and C are now available.

https://toph.co/problems/contests/criterion-2021-round-10 With each problem, you will find the editorial for the respective problem. FR_CR.

Editorials are out and problems are open for submission!

_Dormammu_ can I ask for today's contest review?

Thank You for your feedback. Anyway, please enjoy today's contest!

Whenever I got a Wrong Answer or TLE verdict, I never forget to scream with the word $$$F**K$$$.

iOS Developer in a growing company.

I am a University drop out. I got my job completely based on competitive programming. I have a much lower rating. There are many companies, who don't care about anything else.

You got the round number wrong. 684 is the upcoming round.

You can check this out.

Author: "or post memes in the comments if you can't solve any."

Me: "How to make good programming memes google?"

System testing is in quarantine.

I don't know, but is it legal to "download some version of the language and write a compile + run command"? It would be nice to have swift on Codeforces.

Thank You. I never solved problems on Atcoder. I will now.

We will publish one as soon as possible.

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

Now, we have score 750 for problem A. Let's wait for another challenging disaster.

Reminder: 4 years passed

Finally, Monogon is back!

Our tradition is to memorize maths to pass exams.

Search in linkedIn or youtube.

Seems like codeforces is in trouble.

The contest should be unrated.

24k+ participants already!

Thank You. I will try to write more.

Finally, memes are on Contest announcement blog post :v

Codeforces runs way more than 1e9. Check in the custom test.

Can I ask for a review? If oy can tell me if you can understand it?

Can I ask for a review? If oy can tell me if you can understand it?

Not understandable?

In (Uva) currently named onlinejudge.org, there is a rank list based on the efficiency for each problem.

I can never understand your bad time. Or how you feel. But think of those programmers who are training from the things you've created. They will lose something very important to them. So please consider to up those sites. It's just my personal opinion. And you are also helping someone. Helping someone should feel good.

B1, B2 count as 1 problem.

Hope so.

Is there any chance that the contest will be canceled?

In my language, the Pronunciation of Xor means fever. That means "mohammedehab2002 and his fever".

I hope today there will be something other than xor.

They have fixed the wrong answer issue. Submissions working properly!

Thank You.

If there any update on this topic? Is it safe to solve on the live archive?

Round 544 ( Div.3 )

Ranked 139. +128.

This was the first contest I became an Expert.

I've solved 5 problems in this round, including the last problem.

I solved C by searching oeis.

Who else thinks codeforces should stop setting problems those can be solved by searching online?

Hope to be in the top 1% within the end of this year.

ThisIsMe's hacks. Seems like cheating.

Server in trouble?

Hope this contest will have some graph and DS problems.

From my point of view, problem description is not good enough.

You are mistaken. It's +1012.

Seems like blog isn't working.

Very much appreciated.

Looks like this contest can't be a rated contest. Is it so, please make the announcemant!

Thank You

It's completly okay! Thanks for all of your effots.

Thank You.

I want to know how much time I can resume. Like I logged in. I want to start the challeges after about a month. I haven't started the contest. Thank You.

After log in with a referal, how much time I have before the referal get expired? Before sending a request command?

Maybe you forgot to say — "Nope, you still can. With many downvotes."

Where is the editorial?

Problem C — test case 3. Can I have some example?

What is the test case 5 for DIV.2 D?

Programmers are so bored in quarantine, they are giving downvote to maximum comments O_o

Getting aged waiting for rating change O_o

Seems like codeforces is in some kind of server related trouble. System testing isn't finished yet. Once it finished, you will get your rating.

I think you should practice implementation problems and fast solving and quick idea generating. Cause for 1500+ algorithomic problems are not that necessary. But practicing algorithms are good! You can also practice vertual contests and upsolve them. All the best.

When the problem scroring will be posted?

Just think about a little combinatorics. Suppose we have three basic color. Red , green , blue. How many new colors can be created using these colors and the colors that can be created from these colors and so on? Problem setting is just like this way. Happy Coding!

I am not Walter White XD!

silent_sky Yep

Rice + ( Chicken / ( Dal + Egg fry ) / ( Dal+ Potato fry ) )

Have rest. Health is the top most priority.

Quarantine is passing fine with cooking and coding.

Be safe everyone.

Already 22000+. Today total registration gonna be 24k+

Stay Home. Stay Safe.

Be a Compititive Programmer.

Thanks to codeforces for giving us opportunity to participate in too many contests. I have a request. Please make contests more frequent during this hard time.

18584 registrations! Still increasing!! All the best everyone!!!

Don't use scanf/printf while using ios

My Submission

I've solved this problem using MO's algorithm. First I've transformed the given tree into an array based on traversal order. Two index for every node. One for starting time another for finishing time. Within the segment lies the others vertexes of it's subgraph Then based on query nodes, I've a range for left and right. Then I ordered them in MO's ordering. In the MO's for add and remove function, I used two counter array. One for counting the appearances of the colors. And number of appearances of number of colors

Effect of Corona Virus situation. 17500+ registration.

15600+ registration! Get ready for long queue! O_o

There is a search option in codeforces to find any types of contest. You will find it in the contest section.

Seriously man!O_o

You can read this answer written by I_love_Tanya_Romanova

What's wrong with the system testing? Does anyone knows?

Okay. I'll wait for your post.

I am in. But I can't manage same time as yours. I'll participate every day that I can tell.
