Contests
The International Olympiads in Informatics are an algorithmics contest for secondary school students.
I participated twice and won a bronze medal in 2001. Then I became a member of the
France-IOI association, which trains young students to select 4 of them every year for the contest. The website features online courses and exercices, with an online judge.
