auto_awesomeAI EXPLANATION

This function calculates the n-th Fibonacci number using a recursive approach.

COMPLEXITY

Time: O(2^n) — Exponential

Space: O(n) — Linear

Logic breakdown:1. Checks if n is 0 or 1.
2. If not, it calls itself twice.
Recommendation: Use memoization to improve performance to O(n).
