Write a generator function that returns a generator object which yields the fibonacci sequence.
The fibonacci sequence is defined by the relation Xn = Xn-1 + Xn-2.
The first few numbers of the series are 0, 1, 1, 2, 3, 5, 8, 13.
Input: callCount = 0
Output: []
Explanation: gen.next() is never called so nothing is outputted
Constraints
0 <= callCount <= 50
