Hello everyone!

On April 28, the II Olympiad of School 54 in Programming took place.

Today, on April 30, 2023, 18:05 UTC, I will host a mirror of this Olympiad.

There will be 8 problems offered and 3 hours to solve them.

The difficulty of the contest is at the Div 2-3 level.

The Olympiad is conducted in IOI format with the following rules:

Each problem is worth 100 points, of which 70 points are awarded for passing individual tests set by the jury (1 point for each test), and 30 bonus points are given if the program passes all tests set by the jury. The tests presented in the problem statement do not earn points, but passing them is necessary to test the main group of tests. Time and the number of submissions do not affect the Olympiad results. The maximum score obtained from all submissions is assigned for each problem.

Acknowledgments to the people who made this round possible:

- Thanks to HEARTOWAVE and vbobrov for providing two problems that made the round even more interesting.

- Thanks to testers: vbobrov, BlackDwek, ZooMo, Cyanprism, as well as awoo and his team soup, Minder, ermukanoff, and Sayleyd. Thanks to all of you, the problems have become much better.

- I thank Squantus for listening to and discussing problems throughout the year.

- Special thanks to the team of the Center for Pedagogical Mastery (CPM) for providing the technical capability to conduct the Olympiad as an offline event at the highest level.

- Thank you, MikeMirzayanov, for the wonderful Codeforces and Polygon systems, which make it extremely convenient to conduct competitions.

I strongly request that those who are already familiar with at least one task from the Olympiad do not participate. This includes, but is not limited to, participants of the on-site Olympiad of School 54 and participants of the MPSU Olympiad of 2023.
