Educational Round 9 (Goodbye 0rang3) (0/1000)

Contest Description
Problems very roughly sorted in difficulty order. No plans for formal editorial at the moment, but if u wanna get hints/sol u can try asking on discord. Thanks to errorgorn for overseeing and zaneyu for testing and setters (credited in respective problems) for setting. Don't thank the coordinator because James actually did most of the coordinator's work. (edit: Jamie deserves credit too ~alien) To 0rang3: Unfortunately I am unable to write as eloquently as errorgorn did in edu8. Thanks for everything you have done for the IO community (and beyond, for the record), as a leader/teacher/mentor/setter/contestant/developer/generally very orz human being (or orange? or vulpix? or :steam_locomotive:? who knows). I know your exams haven't ended but you've effectively already graduated (and your exams are almost over anyway), all the best in your future endeavours (hopefully I'll get to watch them unfold)! Goodbye 0rang3, but also hello. ~hhh To 0rang3: Wow we've come so far from not recognising each other in NOI :clown:. Thanks for all you have done for the IO community, but also for the great impact you've had in my life, from the advice you gave for IOI to being so patient with me when I was (and am still) trying to figure out stuff about the judge, and much more. All the best in your future endeavours and hopefully this isn't goodbye :) PS: I'll try not to break the judge too much :p ~alien To 0rang3: Thanks for all you have done for the IO community and the NUSH community as well. Without you, I am sure all of our lives would be very different. Thanks for helping me create my first problem, fixing all the stupid things I did (before and during the contest :clown:), and also helping in several subsequent April Fools Problems. I hope you can choo through all of your hardships and persevere!!!(yes this sentence was just for a pun) Hopefully, will meet again later in the train of life. Sayonara bromine2 :) ~ zane
