extended deadline for submiting solutions
by andrzej - Monday, June 10, 2019, 09:05:34

Since some of the participants of the challenge reported that the submission system was prematurely closed and they could not submit their final solutions, we decided to extend the deadline until the end of this day (10.06.2019 23:59 CET).

We are sorry for the caused confusion.
