TOKI KSN Contest 2020 Unofficial Editorial

Revision en9, by Berted, 2021-01-15 11:44:25

This is the unofficial editorial to KSN 2020 (Indonesia's National Olympiad in Informatics), more information about the contest can be found on this blog post.

You can read the editorial here.

We decided to make this editorial for two reasons:

  1. The editorial is usually only available in Indonesian, so we decided to write it for the international community.
  2. The contest was held 3 months ago, but the Scientific Committee's editorial is still not released yet.

I would like to thank prabowo, yz_, Pa.Nic, nightlight, and rama_pang for helping to finish up this long overdue editorial.

Any issues with the editorial written can be asked here. We will try to respond when we are available.

Thank you and hope this could be useful!

UPD: Regarding problem 2C, the scores are always rounded down as can be seen from the given scoring formula.
