The problem set of PSUT Coding Marathon 2018, which was held last Saturday, will be available in Codeforces Gym tomorrow, 16.05.2018 19:35 (Московское время).
Previous problem sets:
Contest length is 4 hours, with 10 problems to solve. Difficulty of the contest is similar to Codeforces Div.2 rounds. Contest is more suitable for individual participation.
UPD: Contest starts in less than 15 minutes.
Please note that the memory limit for problem C should be 4 MB according to the problem statement. However, I couldn't set it to 4 MB because Java solutions won't run (initial heap size > 4). The memory limit is there to make you think a little bit more and write less.
UPD1: As Codeforces was down, the contest will start at 16.05.2018 19:35 (Московское время).
Good luck and have fun!
