3681. Maximum XOR of Subsequences

LeetCodeArrayMathGreedyBit ManipulationOpen on judge ↗

You are given an integer array nums of length n where each element is a non-negative integer. Select two subsequences of nums (they may be empty and are allowed to overlap), each preserving the original order of elements, and let: - X be the bitwise XOR of all elements in the first subsequence. - Y be the bitwise XOR of all elements in the second subsequence. Return the maximum possible value
