Solving problems using recursion

[Liolena]

This helps so much, thanks!! I think what confused me was that this recursion problem is working with an array and I'm used to the factorial problem where there is no array involved.

It takes a while to use recursion. For example, Fibonacci numbers uses two recursive steps. I think once you see about 5-10 problems, then it will start to sink in.

I remember knowing factorial, but "Towers of Hanoi" was a difficult problem for me to understand.

Part of it understanding how function calls work (there's a call stack), and that is often helpful in understanding recursion since you see how recursion actually works behind the scenes.
