There are many fails on test 4. But it is absolutely correct, both test and answer were checked by hands multiple times. Look for error in your code.

Take a look at the sample inputs again.

I've checked my formula with both kinds of formulas given in this article:
(if someone is interested in full version of article - mailto Oracle@acm.lviv.ua)
I use BigInteger in Java - should be no precision issues.
Results are the same for all rectangles with 1 <= sides <= 100 and for about a billion random test cases with 1 <= side <= 1000000.
And still WA#4((( Is it definitely correct?
Now I wonder if the problem is exactly in checking if one rectangle fits into others? Or I've missed something?

Sorry for complaint. Seems that tests are correct - I've misunderstood the statement.
