What are the advantages of iterative functions over recursive functions?

Iterative functions generally use less memory and can be more efficient than recursive functions, especially for large inputs.

Can you explain why memory usage is a concern with recursion?

Sure! Each recursive call adds a new layer to the call stack, which can lead to stack overflow if too many calls are made.

Are there situations where recursion is preferred?

Yes, recursion can be more intuitive and easier to implement for problems like tree traversals or when the problem naturally fits a recursive structure.

What about performance differences between the two?

Iterative functions often have better performance due to lower overhead, but recursion can be optimized with techniques like tail recursion.

Can you give an example of a problem best solved with recursion?

A classic example is the Fibonacci sequence, where recursion provides a clear and simple solution, despite potential inefficiencies.
