What is the performance of recursive functions?

The performance of recursive functions can vary based on their implementation. Generally, they can be less efficient than iterative solutions due to overhead from function calls and potential stack overflow.

Can you explain why recursion might be less efficient?

Sure! Each recursive call adds a new layer to the call stack, which consumes memory. If the recursion is deep, it can lead to stack overflow. Additionally, repeated calculations in naive recursion can lead to exponential time complexity.

Are there ways to optimize recursive functions?

Yes! Techniques like memoization can help optimize recursive functions by storing previously computed results, reducing redundant calculations.

What are some examples of problems that are best solved with recursion?

Common examples include tree traversals, the Fibonacci sequence, and solving puzzles like the Tower of Hanoi.
