Hello!

I uploaded 2022-2023 Winter Petrozavodsk Camp, Day 4: KAIST+KOI Contest to the CF Gym.

Problems are from KAIST 12th ICPC Mock Competition, with the exception of A, B (KOI 2022 Finals), and C (hard to explain).

Problems are authored by:

• ABC: ko_osaga
• D: circle-oo, queued_q
• EKL: mo_onrabbit2
• F: mo_onrabbit2 Worteltje Retro3014
• GI: Worteltje
• J: queued_q
• HM: kclee2172

I could be wrong, and I wish I am, but it feels like this is the last camp contest I will organize. Hope you had fun participating in the contest, as much as I enjoyed preparing the contest so much!
