Thanks misof for writing the problems and coordinating the round.
This is the second SRM of Stage 2 of TCO20 Algorithm Tournament and TCO20 Regional Events Qualification

Cannot login into the Web Arena. Receiving "Login time out. Please try again at later time."
Same, although the applet seems to work.
You should be able to log in now! :) The issue has been fixed.
Yes, logged in, thank you.
Hope that such situation wouldn't repeat during the round.
Hello, I wanted to ask that when is the round rated for us? 1. after register 2. after opening a problem(but not submitting)
Yes, the rules say that — If you register for a rated event and proceed to open any of the problems during the coding phase, your rating will be affected following the match.
Gentle Reminder: Match begins in 2 hours!
In the Java applet, I and many people I know can't enter past contest's arena.
Is there any problem going on with the arena?
Unfortunately, indexing of the old problems and data is very slow and thus it takes a lot of time on some of them.
Very sorry about that!
I would suggest using Web Arena for the same for the moment. We are not focussing on improving this as we are dedicated to bringing the new arena asap.
That doesn't affect live contests right? I assume it is safe to be on the applet for today's SRM.
Why is the web arena so slow to load? I tried registering 3 minutes prior the ending time of registration but it didn't open :(
The arenas have been shit for a long time, that's a well-known fact.
Everyone's having such interesting contests... and I'm just sitting here wrangling

in EnlargeTheCave is there any need of BFS?
count all resticted '#' that is Adjacent to 'K' and subtract it out from total number of '#'.
Correct me if i am wrong?
You are wrong, this doesn't even work on the examples. The kobolds can block you from accessing parts of the rocks. Remember that the cave must be connected, you cannot just change random '#'s into '.'s.
E.g., example 3 is the following:
The biggest cave you can make has area=9, even though you have a lot of rocks on the right.
