Question

Compare Iterative and Recursive algorithm to find out Fibonacci series​

Answer 1

❗ ANSWER ❗

Further calls of fib(x) for known values may be replaced by a simple lookup, eliminating the need for further recursive calls. This is the main difference between the iterative and recursive approaches, if you are interested, there are also other, more efficient algorithms of calculating fibonacci numbers.
