Minimum XOR

CodeChefRating 1154Open on judge ↗

You have $N$ integers - $A_1, A_2, \ldots, A_N$. You have to make the [Bitwise XOR](https://en.wikipedia.org/wiki/Bitwise_operation#XOR) of all the elements as minimum as possible. You are allowed to remove at most one element. Note that this means that you can also choose to not remove any element. What is the final minimum XOR that you can achieve after removing at most one element? **Note:
