I don't quite understand this problem. For what I understood, the answer should always be 50%!
Could someone please explain me?
Thanks!

You misunderstood the problem ...
You have to find the initial-cost of the whole sphere using a very well-known formula.
Then, since we divide it into n parts, the sell-value will be n x sell-value of each part. The sell-value of each part is also pretty obvious, just be careful on certain input(s).
Now since you got sell-value of the sphere and also the initial-cost ... then it's easy to find the profit. If you're on the right track, you will come down to a very very simple formula ...

My AC-ed solution didn't use that formula ... and I had to make one special case for one input.

Mind the variable type you use...
Recall that 0 < N < 2^31
P.S. Remove your formula above, plz...

The formula is correct.
But be very careful with that. Use long long in C and extended in Pascal.

i tried to solve the problem 10499 too many times. I'm gonna be very angry.
I think I got the right formula and I tested different things like handle the 100% output and over things.
Can anyone give me a hint please ?

Explain the method you used, or submit the portion of your code that generates the answer. Then I may be able to help.
