What are the differences between iterative and recursive binary tree traversal?

What are the differences between iterative and recursive binary tree traversal?

Iterative traversal uses loops and a stack, while recursive traversal uses function calls. Both achieve the same result.

Can you give me an example of both methods?

Sure! For recursive, you might use a function that calls itself for left and right children. For iterative, you'd use a stack to keep track of nodes.

Which method is more efficient?

Iterative methods can be more memory efficient since they avoid the overhead of recursive calls, especially for deep trees.

Are there any scenarios where one is preferred over the other?

Yes, recursive methods are often simpler and easier to read, while iterative methods are better for large trees to avoid stack overflow.
