What are the performance differences between iteration and recursion?

What are the performance differences between iteration and recursion?

Iteration generally uses less memory than recursion because it doesn't involve the overhead of multiple function calls.

Can you explain why recursion might be slower?

Recursion can be slower due to the overhead of maintaining the call stack and the potential for stack overflow with deep recursion.

Are there specific scenarios where recursion is preferred?

Yes, recursion is often preferred for problems that can be divided into smaller subproblems, like tree traversals.

How can I optimize recursive functions?

You can optimize recursive functions using techniques like memoization or converting them to iterative solutions.
