We're not here to do your homework. Why don't you describe it, and I'll tell you if you're right.

I have not written the function. I was asked this question by a friend which he had got in an interview. These days I am trying to solve as many questions as possible as I learn more from it. If the question is not clear then I can re-send it with exact words.

If _you_ don't solve the question, what do you expect to learn? :(
