What are some alternatives to recursion?

What are some alternatives to recursion in programming?

Some alternatives to recursion include iteration, using stacks, and tail recursion optimization.

Can you explain how iteration works as an alternative?

Sure! Iteration involves using loops (like for or while) to repeat a block of code until a condition is met.

What about using stacks? How does that help?

Using stacks allows you to manage function calls manually, simulating recursion without the overhead of multiple function calls.

Are there any specific scenarios where one method is better than the other?

Yes, for example, iteration is often more memory efficient than recursion, especially for deep recursive calls.
