Guys ! I found Karan Gujjar.

Request to Admin and People, Please don't remove this post, this is a serious scam, please read it at least.

He's once again scamming people, but this time on LinkedIn.

Kumar K this is his LinkedIn

He is now pretending to be an ex- Media.net employee and scamming college sophomores and freshers mostly, selling shitty courses and taking money for guidance.

I asked him 3 easy questions.

1. What team did you worked on at Media.net
2. Who was your recruiter?
3. Name any collegue that worked with you on Media.net

But, he would delete my comments and block me.... (the usual karangreat tricks)

I tried to be a whistleblower and expose his tricks many times on LinkedIn but he somehow reports and get my account removed. So, im making this post here.

I'm quite surprised young kids are actually falling for his scam, his whole LinkedIn is a sham, no proofs and only boasting (again karan gujjar cant live without boasting) .

Read his old discuss posts and you'll see a connection: link

I request everyone to be aware of such scammers online, and don't pay even a single penny to him. He's just a jobless cheater who never achieved anything big in life.

Now he works at Amazon

kshitij_sodani senpai ! please take me as your disciple.

So ICPC Qualification is happening on Codedrills.

I went to register on Codedrills and im facing this annoying error for last 30 min. I have verified my email but still its showing me verify your email, and sometimes dashboard is showing An error occured.... message

It makes me worried because ICPC Qualification and Regional will be happening here.

I have high hopes from Codedrills, Please don't let us down. We are looking forward to a smooth, balanced and fair competition.

Maybe organize some more contest, to test the website load handling capacity

can karangreat leave doing codeforces forever?

just leave codeforces and competitive programming

never come back !

for those who was wondering like me, the very popular post by Let_it_GO__90 disappeared suddenly.

Maybe i thought justice was served or whatever. But then i checked the contribution ranklist and there he was Let_it_GO__90

or Let_it_GO__90

YES ! He changed his username ! and deleted the blog as well !

For those who still don't understand, he choose a controversial topic, made it go boom and when he reached 14th place on contribution. He deleted it.

Now he might make story like foo company was blackmailing me etc but why did you changed your username

its so awful he had this planned probably to climb the contribution in 7 days, then delete the post and come clean with a new handle and 158+ contribution

HE IS TRYING TO GET RID OF THIS BLOG AS WELL BY DOWNVOTING IT

A request to all problemsetter, testers and anyone associated with a contest.

Please create strong pretest.

Problem A in Round 671 had such weak pretests.

Same goes for D2 and C.

and many people failed on other problems as well.

I feel terrible right now... I got FST in A,C,D2 at the same contest.. this is ridiculous... Maybe spend sometime more on pretests next time.

1335E2 - Three Blocks Palindrome (hard version)

In this problem, the solution outlined by the editorial is $$$O(n*200*200)$$$, here $$$N$$$ <= $$$200000$$$.

How is the solution able to pass with that time complexity on a constraint like this?

How do i solve problems of old topcoder rounds ?

For example, If i want to solve this https://community.topcoder.com/stat?c=problem_statement&pm=4561

I have looked everywhere, isn't there a simple submit button which can give verdicts normally?
