Fibonacci Numbers
Detailed guide and Python implementation for the 'Fibonacci Numbers' problem.
Problem Statement
Write a function nth_fibonacci(n) that returns the nth Fibonacci number. Assume F(0) = 0 and F(1) = 1.
- •0 <= n <= 100
Examples
nth_fibonacci(9)
34
F(9) is computed as F(8) + F(7) = 21 + 13 = 34.
nth_fibonacci(0)
0
F(0) is 0.
