Hello, Codeforces!
On wednesday, 10 june 2020 г. on 17:35 (UTC+3) will take place End of the learning — Beginning of the tour contest (Div. 3).
This is my first round (mashup, because for creating trainings I haven't got rating, because I need to stop writing contests on the phone) with my tasks. Competition will be held according to the rules of ICPC. Penalty for every wrong submission is 10 minutes. 20 minutes before contest table will be freezed.
You will be given 6 tasks and 2 hours. I wish you like it. I have high hopes for E task.
Ahmad Ahmadsm2005 Said, Ahmed ahmedfouadnew Fouad, Matvey Irpacci Kulinich and Maxim Xennon Karpuk helped me with testing tasks. Also thanks to Mike MikeMirzayanov Mirzayanov for systems Polygon and Codeforces.
I wish you luck!

Upd3: I have problems with E, and so solves with table bigger than 4×4 will be rejected.
Upd4: I fixed Е, and now all is okay! Good luck! Registration will be opened tomorrow in 5 hours before starting!
Upd5: I decided to add one more task, and now the number of them is 6! It was tested only by me, but I wish all is good!
