LeetCode Question 28: Find the Index of the First Occurrence in a String.

Given two strings haystack and needle, the task is to find the starting index of the first occurrence of the substring needle in the string haystack.

If the substring is not present, return -1.

This problem focuses on string matching techniques, where we compare parts of a string with another string. A simple approach involves checking all possible substrings of haystack and comparing them with needle.

This implementation uses the substr() function to extract and compare substrings, making the solution easy to understand and implement.
