DP with Memoization | Dataford Interview Questions

Write a recursive algorithm to solve a classic dynamic programming problem, such as the Fibonacci sequence or the climbing stairs problem, and then optimize it using memoization.

Implement the Fibonacci version using fibonacci(n). Return the nth Fibonacci number, where F(0) = 0 and F(1) = 1. Explain why the naive recursive solution is inefficient and how memoization improves its complexity.

Constraints

0 <= n <= 30
n is an integer
Return an integer

Function Signature

def fibonacci(n):

Whenever you're ready, walk me through your approach or go straight to the code. The requirements are in the Question tab.
