LeetCode 1521 | Bitwise AND + Subarray Trick | C++ Optimized Solution

In this video, I break down an advanced bitwise problem that combines subarray analysis with clever optimization techniques in C++. This problem looks intimidating at first, but with the right approach, we can solve it efficiently!

💡 Problem Summary:
Given an array `arr` and a target integer `target`, find the **minimum absolute difference** between the `target` and the **bitwise AND of any subarray** of `arr`.

✅ What you’ll learn:
- Bitwise AND behavior across subarrays
- Sliding window + set optimization
- Why brute force won’t work here
- Full C++ code walkthrough
- Dry run and intuition
