Hello CodeChef Community!
We’re happy to announce the 60th edition of your beloved three-hour coding jam. Yes, it’s time for LTIME60 for the month of May. Looking forward to having you join in the fun! Joining me this time on the problem setting panel are:
Hopefully you guys enjoyed the contest. We tried to answer as many relevant comments as possible. If yours was not answered, or answered late, please try to read problem statement carefully next time.
The editorials for all6 problems are posted at discuss, so that you guys can read, debate and share approaches for the problems.
One request I have from community as a whole is, these 6 editorials had to be written quickly (in a span of 2 days) and hence, were written in a little haste. There can be some silly errors like spelling mistakes, incorrect link to problem etc. Hence, I’d request the community to point out any such mistake, ask clarifications for any unclear part &etc. so that we can further enhance the editorials.
Also, I did not get much time to analyze a lot of solutions during contest to write in editorials, so any alternate approach other than editorial is very much welcome. I will update bonus corner with any relevant material I find.
Editorialist’s code will be put on demand, and I will try to ask setter and tester to comment their codes nicely, before @admin links them.
Finally, for sake of immediate access, setter and tester’s codes are copied in editorials (will be visible when you click the “Show” button beneath the respective categories). You can copy the solutions and paste them at any place you are comfortable reading.
Thats it from my side,
Thanks and Regards @vijju123
I think the tests for the problem TSUM2 for the second subtask is not correct. My code, which I expected gets partial score, gets verdict WA, after that I added the check in code, that the diameter in the given tree is no more than 200, like it’s said, but it gets verdict RE on the two out of 4 testcases in the second subtask.
Unfortunately, there were misconfiguration in test-cases of TSUM2 which resulted in some test-cases going to wrong subtasks, we have fixed it and rejudged all solution, it has affected about 5 people, those who were trying full task from the beginning weren’t affected by the issue.
The maximum rating increase for a user is 100+75/(no of contest) + 50000*(ratings-1000).
So for a user hit by plagiarism hammer, it’s gonna take two much time for get ratings to their original level, even if i scored very good rank (like only 150+ even though I’m in rank 50 of Div1 right now).
Please increase the max rating bar…
Thank you for that dear! Working hard for editorials. It was like, 5 editorials to be done in 2 days - which is a stressful/tough deadline to meet xD. Working hard for the editorials. They might seem as if written in haste (due to spelling mistakes etc.) but those all will be corrected in due time, once they are posted and I finish the set
