Hi!
The recurrence relation that you have used is not working fine. That is the reason I suggested that approach, its a bit easier and more efficient.

Yes Sir, I understand that. But actually I am not able to understand recursion properly and I wanted to know where am I making mistakes. So, if you could tell me the mistake in my recursive call, it would be a great help.

Thanks!
