How can I convert other recursive functions to iterative ones?

Can you explain how to convert a recursive function to an iterative one?

Sure! The key is to use a loop and a stack or queue to manage the state that would normally be handled by the call stack.

Could you give me an example of converting a recursive factorial function?

Absolutely! A recursive factorial function looks like this: function factorial(n) { return n === 0 ? 1 : n * factorial(n - 1); }. To convert it iteratively, you can use a loop: function factorial(n) { let result = 1; for (let i = 2; i <= n; i++) { result *= i; } return result; }.

What about converting a recursive Fibonacci function?

For Fibonacci, the recursive version is function fib(n) { return n <= 1 ? n : fib(n - 1) + fib(n - 2); }. The iterative version would be: function fib(n) { let a = 0, b = 1; for (let i = 2; i <= n; i++) { let temp = a; a = b; b = temp + b; } return b; }.

Are there any downsides to converting recursive functions to iterative ones?

Yes, while iterative functions can be more efficient in terms of memory usage, they can be less intuitive and harder to read for complex problems.
