Well ... My solution gives the right answer for the sample test case , for all forum test cases, and for test cases [1,11]. But, Wrong Answer #12 :S. What's the trick.. ?!
Every test case I test on my solution works fine for me.
Does anyone know some more tricky test cases???

May I say "Yo Brother"? :D

I have the same problem.
Hope somebody give us answers . . . .
