ZOJ Monthly, January 2019 will be held on Saturday (time). The main problem setters are chenjb and Claris.
It will last for 5 hours and have 8-9 problems in total. Since there is no rating system(Thanks to MudCoal, we may have one in the future) in our Zhejiang University Online Judge, it will be unrated. And I guess the difficulty is as a normal Educational Contest in Codeforces.
All problem ideas come from members of Zhejiang University Programming Contest Setting Team and most of them have already been used in the Internal Member-Selection Contests in ZJU held in July, 2018. They have been carefully selected, modified, tested by our problem setters and rearranged into this Monthly contest eventually.
Special thanks to Claris for helping me testing problems, modifying the content and some other matthers. He even gives better and stronger solutions to some problems, which make them more interesting and challenging. I am very grateful.
Also thanks TsReaper for the tech support and zimpha, lyk248289469, Sugar_fan, HbFS-, johann_wang, Onlynagesha, zhhhplus, etc for their ideas.
There have been less ZOJ Monthly Contests these years. Therefore, we cherish every chance and wish to make every Monthly contest as good as possible. I really hope all of you can enjoy this contest. Can't wait to see you guys in Saturday!
