Mar 19, 2009 · Recursion is good for proto-typing a function and/or writing a base, but after you know the code works and you go back to it during the optimization phase, try to replace it with a loop. …

For fibonacci recursive solution, it is important to save the output of smaller fibonacci numbers, while retrieving the value of larger number. This is called "Memoizing". Here is a code that use memoizing …
