SPLIT With XOR Not X

For an array $A$ and a number $X$, let's define $f(A, X)$ as follows: - If it is **not possible** to split $A$ into several consecutive subarrays in such a way, that the [XOR](https://en.wikipedia.org/wiki/Bitwise_operation#XOR) of all elements in each subarray is **not equal to $X$**, $f(A, X) = 0$. - Otherwise, $f(A, X)$ is equal to the **largest** possible number of subarrays in such a split.
