You are given an integer array nums
of size n
.
Consider a non-empty subarray from nums
that has the maximum possible bitwise AND.
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 subarray.
The bitwise AND of an array is the bitwise AND of all the numbers in it.
A subarray is a contiguous sequence of elements within an array.
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 <= 105
1 <= nums[i] <= 106
