Solution: Remove Duplicates from Sorted Array

Understand how to efficiently remove duplicate elements from a sorted array using the two pointers approach. This technique preserves the array's order and modifies it in-place, returning the count of unique elements. Gain skills to handle array manipulation with optimal time and space usage.
