Polish Olympiad in Informatics

The POI (called OI - Olimpiada Informatyczna - in Polish) is an annual programming competition for Polish high school pupils. It consists of three stages. Stage I lasts for about a month - during it competitors solve about 5 tasks at home. Stage II (semifinal round) is held in a few cities over the country (Cracow, Gliwice, Poznan, Rzeszow, Sopot, Torun, Warsaw, Wroclaw) simultaneously; it consists of a 3-hour practice session and two 5-hour rounds. Stage III (final round) is held in Sopot in Poland; its round structure is similar to the one from stage II. The best finalists represent Poland in the International Olympiad in Informatics (IOI), Central European Olympiad in Informatics (CEOI), Baltic Olympiad in Informatics (BOI) and Chech-Polish-Slovak Programming Camp (CPSPC). Many of the finalists take part in the Olympic Camp (ONTAK) held each year somewhere in Poland.

Attention: In the oldest versions of the olympiad (the ones that took place before year 2003, i.e. 9th POI and earlier) some time limits are (much) smaller than 1 second. Well, the computers are much faster now than they were a few years ago...
