Difference between en8 and en9, changed 112 character(s)
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](https://mirror.codeforces.com/blog/entry/83514).↵

You can read the editorial [here](https://drive.google.com/file/d/1m6DlgBEjv1b-oBuRiZouwt6-FIldtDSi/view?usp=sharing).↵

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 [user:prabowo,2021-01-10], [user:Zap,2021-01-10], [user:Pa.Nic,2021-01-10], [user:nightlight,2021-01-10], and [user:rama_pang,2021-01-10] 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.
