Solution: Longest Subarray With Maximum Bitwise AND

Explore how to identify the longest subarray in an integer list where the bitwise AND of its elements equals the maximum possible value. Learn to apply bitwise manipulation principles to efficiently solve this problem using a single pass and constant space.

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 ...
