Solution: Remove Duplicates from Sorted Array
Explore how to efficiently remove duplicates from a sorted integer array using the two pointers approach. This lesson guides you through modifying the array in-place, preserving order while returning the count of unique elements. Understand the process of scanning and overwriting duplicates to solve this common coding interview pattern with O(n) time and O(1) space complexity.

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 ...
