I wanted to know what are different resources from which IOI participants from different countries use to practice. Also where can I find problems and their analysis of previous IOI task similar to IMO tasks which are available at Link
Thanks and have a good day :)
Here you can find all the past contests with tasks, test datas, and solutions.
thanks. for some years analysis are not available. would like to know what are the websites you use for the preparation
I'm not an IOI participant (hopefully only yet), but Yandex has online judge for IOI tasks back to 2003. From what I've heard POI is pretty good for practice.
ok, thanks! Are there any official analysis/editorials for POI tasks? I find them very interesting
There isn't as far as I know, but if you ask for a specific problem in your blog, then I'm pretty sure someone will help you.
