I have written the following function to count the nodes in a BST
without using recursion. It uses iteration.

You don't need all that. A simple recursive implementation follows:

Doesn't meet the spec (which is "to count the nodes in a BST without
using recursion").

Why did you snip my final sentence, which covers that.

Because, to me, it looked like a hand-wave over the whole issue. "To
avoid recursion, use this recursive solution and then remove the
recursion" is not what I'd have called a good answer to the question.
Nevertheless, if you feel I have misrepresented you or been unfair to
you, I apologise. That was not my intent.
