Given an integer array nums, return the maximum result of nums[i] XOR nums[j], where 0 ≤ i ≤ j < n.
Follow up: Could you do this in O(n) runtime?
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 = [0]
Output: 0
Example 3:
Input: nums = [2,4]
Output: 6
Example 4:
Input: nums = [8,10,2]
Output: 10
Example 5:
Input: nums = [14,70,53,83,49,91,36,80,92,51,66,70]
Output: 127
Constraints:
1 <= nums.length <= 2 * 10^40 <= nums[i] <= 2^31 - 1
