Can I be a tester?2
I am up for being a tester if I am eligible :)
same here
this guys a cheater don't make him tester
me? could you clarify why you think so?
Hi there!
Wow, this is an amazing platform — fantastic work by the team and the writers
I was wondering if there’s any chance I could join as a tester. I’d love to try things out early and share feedback.
Thanks a lot, Ali
can i be a tester?
I'd love to become a tester since i can't participate in many contests nowadays
I’m interested in being a tester!
Sir, Can I be a tester? I would be so glad to become a tester.
Reminder: The contest starts in 5 hours.
I am getting the following error while using the editor for problem A
cat stdout undefined method `chomp' for nil:NilClass
# 1
sample
cat stdin 4 1 5 3 1 5 1 1 5 10 7 7 7
cat stdout undefined method `chomp' for nil:NilClass
cat expected 3 1 0 1
same, and on all problems now, even problems that i already sent and that passed, and if I try to send as I file, it stays on Processing 0/18 passed
Curious, but are you also using Rust? I am also experiencing this error while submitting for Problem E, and was wondering what was happening since it compiles fine on my IDE.
No, I am using C++
Interesting, likely an issue with the site. I wonder if the round will be unrated or not due to this issue.
My submission is in processing state from last 6 minutes on problem A.
it now works if you try to submit again
I do not believe so. I just submitted to E, and my code is stuck in processing and shows 0/11 passed despite showing it passed the first case in the editor.
There is a discrepancy in the problem statement vs. what is accepted for problem D in this round. On the problem description, it states
3 0 31
is Expected for the input of Test cases 1-3. However, in the Repovive compiler, it states that
3 0 81
is expected for the initial test cases. Could you fix this + Rejudge?
Could you guys please test my submissions on D and E
We're doing it and announce it when the standing is finalized
For F: our solution is O(nlog(n)*log(a))
For G: the intended solution is proven to have a better time complexity, using the fact that the number of distinct values with square-free kernel equal to C, is about sqrt(max_val/C). Overall, it's O(n^2*root3(n^2.max_val))
Also: all editorials are out from when contest ended. You can access them from top-right of the problems' box

-Ofast, it looks like they compile without-O2Is it possible to submit in upsolving despite not having registered for the contest?
yes
How? It says I need to register for the contest before submitting.
you can find problems of contests on this link :

also now you can enter in any past contest :)
Will it be the standard start time for this site?
when will the winners announced? i saw rating got updated
Hm. I remember being 4th, and my solution for G was accepted. Now in the contest standings I'm fifth without AC on G, and according to this blog I'm 3rd. What is going on?
The rankings are now finalized. You moved into the top 3 because we detected a cheater and removed them from the leaderboard to ensure fairness. That's why you are now a winner.
After the contest, I had AC on problem F in my last submission, so why is my solution now marked as wrong on the scoreboard?
It was a mistake. Please disregard that as it does not affect the ratings or prize winners. I apologize for our mistake.
If you want to know why did that happen: it was a mistake that our internal rejudge (which was for testing purposes) was reflected on the real ranking. In that rejudge your final submission got TLE because it was borderline. The ratings and prize winners were updated before this rejudge based on the correct ranking.
Sorry for the confusion.
Thanks for fixing that, however I remember that after the contest and after some cheaters removed, I was rank 3, and the current scoreboard does not match the order after the contest. It seems that the internal rejudge affected the scoreboard in other ways. (For example, I also remember that Dilhan and maybe some other people had an AC submission to G, which are marked as wrong now.)
You're totally right about it and we try to avoid these incidents in the future.
What happened is:
Before finalizing the rankings and rating calculations, there were some submissions still finishing in the judge queue. After those completed, Golovanov’s submission was accepted, which moved him to 3rd (behind Aleksei and Nuo Chen).
After the rankings were finalized and ratings calculated, we ran an internal rejudge for testing our system, and due to a mistake it temporarily affected what the public scoreboard shows. We will have it back to the correct ranking as soon as possible
To confirm: Dilhan’s official rank is 5 (as shown on his profile), and his Problem G is accepted. The current public scoreboard is inconsistent because of that rejudge incident.
Please be ensured that we did everything in our power to ensure fairness in the final scoreboard. You're totally right to be wondered by it. I'm sorry for that again and we will definitely ensure that this will not happen again in the future.
