Solution: Longest Subarray With Maximum Bitwise AND

Understand how to identify the longest contiguous subarray whose elements produce the maximum bitwise AND value. This lesson teaches you to optimize the solution by focusing on the largest element and its contiguous occurrences, improving efficiency with O(n) time and O(1) space complexity.

We'll cover the following...

Statement

Given an integer list, nums, find the length of the longest subarrayA subarray is a contiguous sequence of elements within the array. where the bitwise AND of its elements equals the maximum possible bitwise AND among all subarrays of nums. The bitwise AND of a list is calculated by performing the bitwise AND operation on all elements within the subarray.

Constraints:

  • 1≤1\leq nums.length ≤103\leq 10^3 ...
