Absolutely!! And it is called a recursive function.

The well known example, a function for calculating factorial.

But remember you need to get back to where you started sometime. Look to see if you can state your problem in normal interation terms. And if you recurse a lot you might run out of stack

It would have been about 100 times faster to try writing a recursive function and testing it than posting here.

I think you'll find that this was done and dusted in about 10 minutes this morning.
