LeetCode 2419: Longest Subarray With Maximum Bitwise AND | Full Problem Solution & Explanation

Показать описание

Hey everyone! Welcome back! 🌟 In today’s video, we’ll tackle Longest Subarray With Maximum Bitwise AND (LeetCode Problem #2419), a medium-level challenge where we find the longest subarray that achieves the maximum bitwise AND. This problem involves understanding bitwise operations and how to handle subarrays in a more efficient way.

🔍 In this video, we’ll cover:

The problem statement explained in simple terms. A detailed explanation of the bitwise AND operation. How to identify subarrays that yield the maximum bitwise AND value. A step-by-step approach to finding the longest subarray with that maximum AND value.
💡 Key Concepts:

Bitwise operations (AND) Sliding window technique Array manipulation Subarray problems in competitive programming
We will also take an in-depth look at how to iterate through the array efficiently, focusing on finding the subarrays that contribute to the solution without wasting time on unnecessary recalculations.

🚀 Example Walkthrough:

We will walk through example cases like nums = [1, 2, 3, 3, 2, 2] and explain how we find the maximum bitwise AND of the subarrays and then determine the longest such subarray. Discuss why certain subarrays have the maximum bitwise AND and how to filter for them.
