How can I convert recursion to iteration?

Can you explain how to convert a recursive function to an iterative one?

Sure! The main idea is to use a loop instead of recursive calls. You can use a stack or variables to keep track of the state.

Could you give me an example of a recursive function and how to convert it?

Absolutely! Let's take the factorial function. The recursive version is factorial(n) = n * factorial(n-1). The iterative version would use a loop to multiply the numbers from 1 to n.

What about handling base cases in iteration?

In iteration, you typically handle the base case by initializing your result before entering the loop, ensuring it starts correctly.

Are there any advantages to using iteration over recursion?

Yes, iteration can be more memory efficient since it doesn't add to the call stack, reducing the risk of stack overflow.
