In this case, using memoization (keeping a table of solved fibonacci numbers would leave your algorithm running at the same performance asymptotically as the iterative counterpart. Big O notation.

Computing Fibonacci with the usual recursion style or normal iteration. However, as i progresses and becomes as big as 10⁵, at no point will the sum be as high 10 and this saves space and time. So.
