Yes i got RTE too, when i sent the little code you posted i got AC :S

Im getting TLE, im using Gift Wrapping algorithm in java, i though it was enough to pass the tests in 3 seconds, given the low bounds (100 points) should i use graham scan?

I have the same problem, please help

I got AC using the Combinatorics equation but i don't understand why does it works.

F(n) = 1+ number of lines + number of intersections

What's the idea behind it? How is that sumation directly involved with the areas produced?

Thanks.
