Hope to see you guys in the ranking!

Update : We're truly sorry for the mistake in CRSHIT. Both the tester and I had the same bug in our solutions :(.

The round turned out to be harder than expected, div.1 also got started on the wrong foot as everyone tackled DAND (which was intended as 6th). I can only assume if the problems were ordered by difficulty, the round would've gone much better. One thing I didn't understand was why don't Div.1 contestants solve the common problems of both divisions first? It seemed unnatural to me that everyone was on DAND for the first hour or so.

Anyway, thanks for participating. I hope you enjoyed the round along with all it's flaws (or at least would enjoy upsolving it as I think the problems are interesting and educational!).
