Link to the mirror! (Please register at the gym)
Hello Codeforces!
I'd like to invite you to the mirror of the 2020 eliminations round of the National Olympiad in Informatics – Philippines. The mirror will be held in the Codeforces gym. The NOI.PH is the Philippines' qualifier for the IOI.
Contest format:
- There are 17 problems over 9 days.
- The problems will have subtasks. The maximum score for each problem will be 100 points.
- The submission that achieves the maximum score is counted towards the final ranking.
- The problems range from easy to challenging. Everyone from the newbie to the grandmaster will find an interesting problem in the contest.
Editorials will be released after the mirror contest ends.
Acknowledgments: The problem setters were kevinsogo, cjquines, Shisuko, andrewting, jabbawookiees, guissmo, verngutz. Thanks to Benq and ekzhang for additional help in testing. Lastly, thanks to MikeMirzayanov for Codeforces, and Polygon, which was used to prepare the problems.

Have fun!
