# Longest Subsequence With Maximum Bitwise AND

You are given an integer array nums of size n.

Consider a non-empty subsequence from nums that has the maximum possible bitwise AND.

In other words, let k be the maximum value of the bitwise AND of any subarray of nums. Then, only subarrays with a bitwise AND equal to k should be considered.
Return the length of the longest such subsequence.

The bitwise AND of an array is the bitwise AND of all the numbers in it.

A subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements (source: wiki)

Example 1:

Input: nums = [1,2,3,3,2,2]
Output: 2
Explanation:
The maximum possible bitwise AND of a subarray is 3.
The longest subarray with that value is [3,3], so we return 2.
Example 2:

Input: nums = [1,2,3,4]
Output: 1
Explanation:
The maximum possible bitwise AND of a subarray is 4.
The longest subarray with that value is [4], so we return 1.

## Constraints:

• 1 <= nums.length <= 10^5
• 1 <= nums[i] <= 10^6
