Hi everyone!

I would like to invite you to the Weekly Training Farm 22 ! The problemsetter is me (zscoder) and the tester and quality controller is dreamoon_love_AA.

It will be a contest in ACM-ICPC style and contains 6 problems. The difficulty is around 500-1500-1500-1750-2500-2500 (compared to Div. 2 Contests)

The contest begins at 19:30 UTC+8 and lasts for two hours.

To join the contest, join this group (as participant) first and find Weekly Training Farm 22 on the Group Contest tab.

In addition, there will be a few interactive problems in this round. Please check the Interactive Problems Guide if you're not familiar with interactive problems.

Good luck and hope you enjoy the problems!
