LeetCode 349 - Intersection of Two Arrays Explained in C++ | Hash Set Easy

In this video, we solve LeetCode Problem 349: Intersection of Two Arrays using C++.

We cover:

* hash set basics
* finding common elements efficiently
* removing duplicates automatically
* step-by-step dry run
* optimized O(n) solution
* time complexity analysis

Example:
Input:
nums1 = [1,2,2,1]
nums2 = [2,2]

Output:
[2]

Because:
2 is common in both arrays.
