Choose an ordering of the numbers to maximize the XOR of a running bitwise process over the array.
You are given an array of integers. You may rearrange the elements in any order.
After rearranging, apply the problem's bitwise XOR aggregation rule to the array and return the maximum value that can be obtained.
This problem asks you to reason about how XOR behaves under reordering and to determine the arrangement that yields the best possible result.
nums.nums.1 <= nums.lengthnums[i] >= 0Example 1
Input
nums = [1, 2, 3]
Output
0
Explanation
Because XOR is associative and commutative, any rearrangement gives the same result: 1 ^ 2 ^ 3 = 0.
Example 2
Input
nums = [4, 4, 1]
Output
1
Explanation
Any permutation produces the same total XOR. Since 4 ^ 4 ^ 1 = 1, the maximum achievable value is 1.
