III. 1 The Programming Section

Art. 6. The contest takes place in one day and consists of a practical examination (May 16, 2015).
The practical test duration is 3 hours and it consists in solving 2 problems using computer algorithmic methods. Solving a problem requires developing a program correctly, efficiently in terms of execution time and used memory space. The curriculum for the contest is the curriculum of the Mathematics-Computer Science profile, Intensive Mathematics-Computer Science profile, according to the level of study.
