XOR Equal

You are given an array $A$ consisting of $N$ integers and an integer $X$. Your goal is to have as many equal integers as possible in the array. To achieve this goal, you can do the following operation: - Choose an index $i$ $(1 \leq i \leq N)$ and set $A_i = A_i \oplus X$, where $\oplus$ denotes the [bitwise xor operation](https://en.wikipedia.org/wiki/Bitwise_operation#XOR). Find the maximum n
