Hi, here's your problem today. This problem was recently asked by Apple:
The Fibonacci sequence is the integer sequence defined by the recurrence relation: F(n) = F(n-1) + F(n-2), where F(0) = 0 and F(1) = 1. In other words, the nth Fibonacci number is the sum of the prior two Fibonacci numbers. Below are the first few values of the sequence:
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144...
Given a number n, print the n-th Fibonacci Number.
Examples:
Input: n = 3
Output: 2
Input: n = 7
Output: 13
Here's a starting point:

class Solution():
def fibonacci(self, n):
# fill this in.
n = 9
print(Solution().fibonacci(n))
# 34
