LeetCode 421 Maximum XOR of Two Numbers - Problem Statement

Find the maximum XOR of any two numbers in the array.

With nums = [3,10,5,25,2,8]:

• 5 XOR 25 = 00101 XOR 11001 = 11100 = 28.
• No pair produces a larger XOR.
• Answer: $28$.

With nums = [14,70,53,83,49,91,36,80,92,51,66,70]:

• Maximum XOR is $127$.

Constraints: $1 \le$ nums.length $\le 2 \times 10^5$. $0 \le$ nums[i] $\le 2^{31} - 1$.
