↵
The problems were created and set by [user:Radewoosh,2019-09-15] and me. Also, thanks to the testers: [user:Swistakk,2019-09-15], [user:Marcin_smu,2019-09-15] and [user:Errichto,2019-09-15]!↵

The problemset was presented at this summer's Petrozavodsk camp. Thanks to everyone at AIM Tech for supporting the contest, including the tasks selection! If you want to know how to hold _your own_ contest on Moscow Workshops in November and participate in the camp for free, [look here](https://codeforces.me/blog/entry/69694).↵
↵
If you're still unsure whether to participate and you like Pokémon, this is your lucky day! You'll be able to help quite a few of them on Sunday. Don't worry, you don't have to finish all the games and watch all the anime in order to solve the tasks! <sub><sub>*but it's a good idea in general</sub></sub>↵
↵
Good luck!↵
