What is the difference between iterative and recursive permutations?

Can you explain the difference between iterative and recursive permutations?

Sure! Iterative permutations use loops to generate permutations, while recursive permutations use function calls to achieve the same.

Which method is more efficient for generating permutations?

It depends on the context. Iterative methods can be more memory efficient, while recursive methods are often easier to implement and understand.

Can you give me an example of both methods?

Absolutely! For iterative, you might use a loop to swap elements, while for recursive, you'd call a function that builds permutations by fixing one element and permuting the rest.

Are there any limitations to either method?

Yes, recursive methods can lead to stack overflow for large inputs, while iterative methods can be more complex to implement for certain cases.
