It's hard to offer help when you don't ask a more specific question.

However, in general what you can do to help follow the recursion is to include an indication of how deep you are.

For example:




And then of course adding or changing the output to show you whatever you're not understanding.

Thanks Jeff. The way to trace a program you have provided helped me a lot.I also did a hand trace as well to get more clarity.
