Should we wait a long time for system testing and rating changes? I mean, maybe real competition won't finish at time we finish?

How to solve D?!

They said in QR such a problem won't happen in future rounds... hmmm

Tried but didn't fix. Maybe I should uninstall and install Firefox

Extension icon disappears.

When I close Firefox and open again calendar item disappears. But when I disables and enables it appears. Can't it start automatically ?!

How to solve E problem ?!


Like this ?!
UPD I understood why minus. I think you you thought it doesn't calculate if your memory exceeds 64MB, but before this submission memory was around 135MB.

hmm got it... So if my solution gets OK in open submission does it mean I have solved that problem I mean it checks all tests ?!

I couldn't understand open/blind submission. What is difference ?! What are advantages of open/blind. Does blind mean : "I don't need feedback" or sth else ?!
