Leetcode 26: Remove Duplicates from Sorted Array - C++ Solution (Two Pointers)
🔴 Subscribe for More Coding Tutorials & Interview Solutions!
In this video, we solve Leetcode Problem 26: Remove Duplicates from Sorted Array using the two-pointer technique in C++.
The challenge is to remove duplicates in-place from a sorted array so that each unique element appears only once and return the count of unique elements.
This approach uses O(1) extra space and runs in O(n) time complexity, making it ideal for coding interviews.
🔍 Problem Overview:
Input: A sorted integer array.
Output: The number of unique elements, with the first part of the array modified in-place to reflect them.
💡 Key Concepts:
Two-Pointer Technique for in-place operations.
Efficient O(n) time solution.
Maintains relative order of unique elements.
