NYOI 2024 Practice Round (0/800)

NYOI 2024 Preliminary Round This is an open practice contest in preparation for the Final round on 11th November 2024. Every participant will advance to final round regardless of their score in this round! Note: The problems in this round consist mostly of problems that are unsuitable for the final round, and are not representative of the final contest. The final contest will have more interesting problems (we hope), and with a more appropriate difficulty curve. UPD: Final editorial is up for review!
