What are the memory usage differences between iterative and recursive approaches?

What are the memory usage differences between iterative and recursive approaches?

Iterative approaches generally use less memory than recursive ones because they don't require additional stack space for function calls.

Can you explain why recursion uses more memory?

Recursion uses more memory due to the call stack, which stores information about each function call until it completes.

Are there any scenarios where recursion is preferred despite its memory usage?

Yes, recursion can be more elegant and easier to read for problems like tree traversals or when implementing algorithms like quicksort.

How can I optimize a recursive function to use less memory?

You can optimize a recursive function by using techniques like tail recursion or converting it to an iterative approach.
