Hi, Codeforces Community!
Codefest'19 — a diverse roster of high-quality programming competitions by Department of Computer Science and Engineering, IIT(BHU), Varanasi is excited to present Perplexed — the constrained programming event.
Perplexed is one of the most innovative events of CodeFest, whose target is not only gauge a contestant's coding abilities but also how one tackles different situations and constraints. The problemset will include all mind-boggling coding problems, ranging from code obfuscation to language constraints, character limits etc
The contest will take place at HackerRank. This contest will be an individual event with a duration of 2 hours 30 minutes, from Aug/23/2019 20:00 IST. With the creativity that the problems will naturally encourage and INR 50,000 at stake, there is absolutely no reason for a programmer to not give this one a shot!
The contest has been prepared by Enigma27, _hiccup, _shanky, hitman623 and me (drastogi21).
UPD1: The contest will start in about an hour.
UPD2: The contest will start in about 15 minutes.
UPD3: The contest has ended.
UPD4: The editorial has been published. You can find the solutions to the problem at HackerRank itself. Feel free to discuss the problems in the comments.
Prizes -
1st Prize-Rs.20000
2nd Prize-Rs.12000
3rd Prize-Rs.8000
1st in India-Rs.6000
1st in IIT(BHU)-Rs.3000
1st in 1/2 year in IIT(BHU)-Rs.1000
UPD: The issue in the checker has been resolved. Following are the winners of the contest. Congrats!

First place in India: IceKnight1093
Really excited about the contest... Haven't done much constrained programming before, so will be a great experience for me.
Excited for the contest!!
Can't wait for the contest!!
Is this contest an April Fool type Contest?
Not exactly, there are algorithmic and other types of problems too: surprise language, codegolf, hack the code etc.
Thanks for Clarification
Why this contest is not listed at https://www.hackerrank.com/contests ?
That is true I was also suprised. But the given link works. Maybe they have thier reasons about that.
Since it's a college contest (by IIT (BHU) Varanasi), so it is listed at https://www.hackerrank.com/contests/college. Also, you'll find two other contests — Mathmania and CTF in that link, which are also conducted as a part of Codefest'19 by the Department of Computer Science and Engineering, IIT(BHU), Varanasi.
Is it rated?
No, it is an unrated contest.
Can you post previous contest links ?

how to solve Odd-One-Out ? I tried 1-2-3-1-3-2-1-2-3-2-1-3 pattern of increments in with seed value of 1 but was able to get only 20 for it
Check pattern on OEIS
Thanks
I got top 3 rank in contest....when will prizes be distributed?
How to solve B (the balls one) ?
Think about output of the following... 2 4 4
How did you reach at this test case ?
I was considering min priority case
Sorry, but isn't the answer 4 only ?
It was a fun contest....had fun solving problems...very good job by Rastogi ji
I really hope there are more contests with similar theme
+1
Help: why is my answer wrong in Minimal Cover? First test case for example:
And a tester I wrote (that doesn't find the mistake):
Their tester had a bug, this is a result of noobs setting problems
But does it still have a bug?
When I submit the code again I still reach the same results:
1) WA on HR, because "All points are not inside circles."
2) But when I run my code on those inputs and check, all points do seem to be inside circles.
Also found another much less severe bug: the constraint 1 <= r_i <= 1e6 doesn't seem to be enforced at all — my wrong solution that prints both 0 radius and huge radius circles passes all cases...
