So, my question is how do I practice. Wish to participate in IOI.
Keeping that in mind, how do you suggest I should practice, assuming I have 3 hours of time everyday. I thought of doing Atcoder, to improve my thinking skills, but I have noticed that IOI problems often require much more coding than simple Atcoder problems. OI checklist is one such option, but I wish to do that a bit later. Further, how helpful is Topcoder for OI styled problems. Should I practice from ICPC problems sets?
Can someone suggest me a sources as to where to practice from? Or like your own experiences of success and how and from where you practised.
You can assume my probable CF rating to be purple.
I think this question is pretty common, and a typical answer is that if you want to practice for OI, you should do OI problems such as from the checklist. https://codeforces.com/blog/entry/62898
