When should I use loops instead of recursion?

When should I use loops instead of recursion?

Loops are generally more efficient for tasks that require repeated execution, while recursion is better for problems that can be broken down into smaller subproblems.

Can you give me an example of a problem that is better suited for recursion?

Sure! A classic example is calculating the factorial of a number. It's naturally defined in terms of itself, making recursion a good fit.

What about performance? Are there cases where recursion is less efficient?

Yes, recursion can lead to stack overflow errors if the recursion depth is too high, and it often has more overhead than loops due to function calls.

How can I convert a recursive function to a loop?

You can use a stack data structure to simulate the call stack of recursion, allowing you to implement the same logic iteratively.
