Fibonacci Calculator

Fibonacci sequence is a famous mathematical sequence, in which the last 2 numbers are summed to get the next number in the sequence. https://en.wikipedia.org/wiki/Fibonacci_number
For example, the original sequence is 0, 1, 1, 2, 3, 5...
Explanation:
1. First, the sequence begins with 0, 1
2. 0 + 1 = 1 = 0, 1, 1
3. 1 + 1 = 2 = 1, 0, 1, 2
4. 1 + 2 = 3 = 0, 1, 1, 2, 3
5. 2 + 3 = 5 = 0, 1, 1, 2, 3, 5
