Python Solution for LeetCode Problem: Find Needle in a Haystack (Index of First Occurrence)

In this LeetCode coding tutorial, we solve the classic string problem: 'Find Needle in a Haystack' using Python. This problem, also known as LeetCode Problem 28, asks us to return the index of the first occurrence of the substring (needle) in the given string (haystack), or -1 if it doesn't exist.

What You’ll Learn:
How to implement an efficient Python solution to solve LeetCode Problem 28: Find Needle in a Haystack
String searching techniques and how to handle edge cases
Optimized approaches to find the first occurrence of a substring in a string using Python’s built-in methods
Step-by-step explanation with examples to ensure a clear understanding of the problem-solving approach
Examples Covered:
Example 1:
Input: haystack = "sadbutsad", needle = "sad"
Output: 0
Explanation: The first occurrence of "sad" is at index 0.
Example 2:
Input: haystack = "leetcode", needle = "leeto"
Output: -1
Explanation: "leeto" does not exist in "leetcode", so we return -1.
