Question: ( 3 5 marks ) The Fibonacci sequence is the series of integers 0 , 1 , 1 , 2 , 3 , 5 ,

(35 marks) The Fibonacci sequence is the series of integers
0,1,1,2,3,5,8,13,21,34,55,89dots
See the pattern? Each element in the series is the sum of the preceding two items.
There is a recursive formula for calculating the nth number of the sequence (the oth
number if Fib(0)=0):
Fib(N)?N=,ifN=0or1???
Fib(N-2)+Fib(N-1),ifN>1
a. Write a recursive version of the function Fibonacci.
b. Write a nonrecursive version of the function Fibonacci
c. Write a program to test the recursive and iterative versions of the function
