#421 Maximum XOR of Two Numbers in an Array
APPROACH
Given an integer array nums, return the maximum result of nums[i] XOR nums[j], where 0 <= i <= j < n.
Example 1:
Input: nums = [3,10,5,25,2,8]
Output: 28
Explanation: The maximum result is 5 XOR 25 = 28.
Example 2:
Input: nums = [14,70,53,83,49,91,36,80,92,51,66,70]
Output: 127
