ZOJ Monthly, January 2019 will be held on Saturday (time). The main problem setter is chenjb and Claris.
It will last for 5 hours and have 8-9 problem 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.
All problem ideas come from members of Zhejiang University Competitive Programming Team and they have already been used in the Internal Member-Selection Contests in ZJU held in July, 2018. After Our problem setters carefully select, modify and test the problem, they are rearranged into this Monthly contest.
Special thanks to Claris for helping me testing problems, modifying the content and any other thing. 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-,[user:JohannWang],zhhhplus,etc for their ideas.
