Given an array of positive integers nums, a subarray is "nice" if the bitwise AND of every pair of elements in different positions is 0. Return the length of the longest nice subarray.
Example 1:
Input: 1 3 8 48 10 Output: 3
Example 2:
Input: 3 1 5 11 13 Output: 1
Input format: Space-separated positive integers.
Output format: Length of longest nice subarray.
