Polynomial Round 2022 (Div. 1 + Div. 2) Editorial

Правка en16, от ChthollyNotaSeniorious, 2022-12-17 21:11:33

Thanks for your participation! I am so sorry for my careless review. We were preparing for this round for many months and made some problems which writers and testers are all like. We do want to give everyone a gold time to enjoy the contest. But carelessness is deadly. In problem B, some test cases should have been made, but we missed them in not only the pretests but also the final tests. In fact, we had not noticed it until some suspicious hacks appeared. I and all co-authors sincerely regret our mistake and hope you can forgive us.

Besides, few people are cyberbullying authors, please do not do so. If you have a bad experience, you can downvote me because of our fault.
