What is Informatics olympiad?

The Informatics Olympiads are competitive programming contests for secondary school students. They require basic skills in algorithms and data structures. In India we have the Indian Computing Olympiads which leads to the International Informatics Olympiad(IOI). The Indian Computing Olympiads are managed by IARCS (Indian Association for Research in Computing Science). The first International Informatics Olympiad was held in 1989 in Pravetz, Bulgaria. It is one of the major science Olympiads besides Mathematics, Physics, Chemistry, Biology and Astronomy. India started participating in the year 2002. Recently, Akshat Bubna got the first ever gold medal for India in 2014 (and also won the Go For Gold challenge by Codechef). IOI 2015 will be conducted in Kazakhastan.
