Solution: Remove Duplicates from Sorted Array
Explore how to efficiently remove duplicates from a sorted array using the two-pointer approach. Understand how to modify the array in-place while preserving order, and gain insight into the algorithm’s time and space complexity. This lesson helps you implement and reason about this common pattern in coding interviews.

Statement
You are given an integer array nums that is already sorted in non-decreasing order. Your task is to remove the duplicate values in-place so that each element in the array appears only once, while preserving the original relative order of the elements.
After removing the duplicates, let k be the number of unique elements remaining in the array. The first k ...
