Discussion of Problem 1793. Tray 2

bad description of the problem

To get AC you should guess, that you could rotate plates upside down! that is absurd, as I think for plates with a lunch!

I see a lot of talking about precision. that you should use integer instead of floating point. but I've got AC using "double" after I accidently understood what the real problem is.

You are wrong. The plates are actually with lunch and could't be rotated upside down. :)

So, I've deleted "rotation" and got WA20. If you are right it means that I used to get AC by wrong algo.
