Hello! The 18th Zhejiang Provincial Collegiate Programming Contest has been uploaded to the Gym.
This contest also serves as Contest 3, Div.A in this year's Moscow Pre-Finals Workshop 2021, so we also prepare an English tutorial. Note that the contest version in Gym is different from the original version used in ZJCPC. We enlarge the data constraint in H and K to prevent some unintended solutions passing.

If anyone can help upload these scoreboards to Gym, we will be very grateful.
Please feel free to discuss problems in comments and hope you enjoy this contest.
