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:

  • 1 <= nums.length <= 2 * 105
  • 0 <= nums[i] <= 231 - 1
