International Olympiad in Informatics (IOI) is one of the most prestigious international programming competitions for high school students. Founded in 1989, it is held annually and brings together top young programmers from over 80 countries. Each participating country selects a team through rigorous national contests. The competition focuses on algorithmic problem-solving and computer programming, where contestants must design efficient algorithms and implement solutions to complex computational problems under strict time limits. Medals (gold, silver, bronze) and honorable mentions are awarded based on performance, representing the highest level of achievement in high school informatics.
