Numbers in exponential notation were deleted from the tests.
All coordinates now are integers from -50000 to 50000. New tests were added and the problem was rejudged.

What is the reason for this?

It was such an exciting adventure to solve this problem in Java! java.util.Scanner is too slow, java.io.StreamTokenizer with standard settings does not understand exponential notation. That was fantastic!

I don't know any other problem that uncovers fact that StreamTokenizer does not support exponential notation. It is very big loss that coordinates are integer now.
