python program to print nth fibonacci number

Title: Python Tutorial - Finding the Nth Fibonacci Number
Introduction:
The Fibonacci sequence is a series of numbers in which each number is the sum of the two preceding ones, usually starting with 0 and 1. In this tutorial, we'll explore how to write a Python program to find the Nth Fibonacci number using different approaches.
Approach 1: Recursive Solution
Approach 2: Iterative Solution
Approach 3: Dynamic Programming (Memoization)
Conclusion:
These are three different approaches to finding the Nth Fibonacci number in Python. Each approach has its own advantages and trade-offs. The recursive solution is simple but may be less efficient for large values of N. The iterative solution is more efficient in terms of time complexity, while the dynamic programming approach with memoization combines the best of both worlds by avoiding redundant calculations. Choose the approach that best fits your requirements.
