Maximum XOR of Two Numbers in an Array
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
28The maximum result is 5 XOR 25 = 28.
Example 2
Input
nums = [14,70,53,83,49,91,36,80,92,51,66,70]Output
127The maximum XOR result among pairs in the array is 127.
Constraints
- 1 <= nums.length <= 2 * 10^5
- 0 <= nums[i] <= 2^31 - 1
