Ys Luogu Pseudo Codeforces Round 1 (individual preferred)[unrated]

Hello, Luogu!

I'm very glad to invite you to the first Ys pseudo codeforces round which will take place on Monday, August 17, 2020 at 14:35UTC+8. It's obvious that this round will be held by pseudo codeforces(much joy) rules.

All problems in this round were created and prepared by \color{black}\text{fhs\_lsqs}, \color{blue}\text{lzx\_zrl}, \color{purple}\text{Imakf} and \color{purple}\text{Daniel\_yuan}. Regrettably, not all algorithms are involved in this contest. But we tried to make them interesting and diverse and hope that you will enjoy them!

You will be given 2 hours and 30 minutes to solve 6 (or 7 or 8) problems in this contest, and we highly encourage you to read all of them :).

We would like to thank:

Ys for being our coach.
? for amazing coordination of this round.
\text{\color{orange}Qiuly.qwq}, \text{\color{orange}Soulist\_x}, \text{\color{purple}starcy}, \text{\color{blue}maojinyang} and \text{\color{blue}3d64s2} for testing the problems and providing invaluable feedback.
kkksc03 for providing such a platform.
\color{black}\bold{MikeMirzayanov} for providing testlib in data generating and special judge.
Google grass-making machine for significant and high-quality translation of the whole annoucement.

Here is the score distribution:

500 — (250 + 500) — 1250 — 2000 — (1000 + 1500)

Here is the money distribution for the first participant who solves the problem：

1 — (1 + 1) — 1 — 2 — (1 + 2)

Regardless of whether you are a trusted participant of the second division or not, if your guzhi is less than 514, then the round will be unrated for you.

Good luck and have fun!
