Maximum XOR Pair
Detailed guide and Python implementation for the 'Maximum XOR Pair' problem.
Problem Statement
Write a function max_xor_pair(arr) that takes an array of non-negative integers arr and returns the maximum XOR sum of any two elements in the array.
- •2 <= len(arr) <= 10^5
- •0 <= arr[i] <= 10^9
Examples
max_xor_pair([3, 10, 5, 25, 2, 8])
28
The maximum XOR is obtained by pairing 5 and 25 (5^25 = 28).
max_xor_pair([8, 10, 2])
10
The maximum XOR is obtained by pairing 8 and 2 (8^2 = 10).
