Median of Uniqueness Array of Subarrays | Count Distinct Elements in Subarrays | C++ Tutorial

In this tutorial, we solve a challenging **array problem**:

Given an integer array `nums`, we generate the **uniqueness array** consisting of the **number of distinct elements in all subarrays** of `nums`. Then, we find the **median** of this uniqueness array.

Learn how to:

* Efficiently count **distinct elements** in subarrays
* Use **sliding window and frequency counting** to optimize computations
* Calculate **median** from a sorted array of subarray uniqueness values
* Implement a **C++ solution** suitable for competitive programming and coding interviews

💡 Topics Covered:

* Subarray generation and analysis
* Counting distinct elements efficiently
* Median calculation for sorted arrays
* Optimized approaches for arrays up to `10^5` elements

This problem is perfect for **students preparing for coding interviews, algorithm enthusiasts, and competitive programmers**!
