2648. Generate Fibonacci Sequence

Easy

---

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

---

Example 1:

Input: callCount = 5
// Output: [0,1,1,2,3]

Explanation:

const gen = fibGenerator();
gen.next().value; // 0
gen.next().value; // 1
gen.next().value; // 1
gen.next().value; // 2
gen.next().value; // 3

---

Example 2:

Input: callCount = 0
// Output: []

Explanation:

gen.next() is never called so nothing is outputted

---

Constraints:

• 0 <= callCount <= 50
