Comment on Fully iterative Ackermann function computation by dmyersturnbull

Correct. Saving function overhead is the sole objective. Since compilers often fail to recognize tail recursion, iterative implementations are often preferred. Recursion and iteration accomplish the same thing, and in general, are really the same. Thanks for your comment. I’ll update my post to reflect this.

That’s just simulating recursion using a stack. Think about how a computer implements function calls using stack frames. All you save is function call overhead, you still need the same amount of storage from a big-O point of view as any other recursive implementation.
