When should I use iterative solutions instead of recursion?

You should consider using iterative solutions when performance and memory efficiency are critical, especially for large datasets.

Can you explain why iterative solutions are more memory efficient?

Sure! Iterative solutions typically use a fixed amount of memory, while recursion can lead to stack overflow due to deep call stacks.

Are there specific problems where recursion is still better?

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

How do I decide which method to use for a specific problem?

Evaluate the problem's complexity, size, and whether it can be broken down into smaller subproblems. Test both methods if unsure!
