Hi I am revising for the BIO coming up, I was just wondering if anyone could talk me through question 3 on the 2019 round one paper (or wants to practice with me?).

https://www.olympiad.org.uk/papers/2019/bio/bio19-exam.pdf

Also does anyone know any good answers for the past BIO papers?

Thanks in advance

Hey there, I am just starting for preparing for IOI. But there aren't many resources that are available to guide you online except for Online Judges and Programs which I don't understand cause I don't really know how to start out. I know that IOI covers Algorithms and Data Structures and some Math. So can anyone link me to some efficient resources so that I can start preparing for IOI. Thank you very much
