    421 - Maximum XOR of Two Numbers in an Array.

    Medium

    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

    Constraints:

    • <code>1 <= nums.length <= 2 * 10<sup>5</sup></code>

    • <code>0 <= numsi<= 2<sup>31</sup> - 1</code>
