Today I am the author of the tasks. I'm a student of Tyumen State University.
I want to thank all those who helped me to prepare the round: Nikita Durynin (Austeritas) for the pair ideas for the tasks, Dmitry Bochkarev (Walrus) and Chernenkov Alexey (Laise) for the testing, Artem Rakhov (RAD) for coordinating the activities, Maria Belova for translating and Mike Mirzayanov (MikeMirzayanov) for a great system.
Today you will visit the Walrusland and help the common citizens and government to solve their problems.
Good luck for everybody, let the best man win!
Winner is Petr. Congratulations!
