Neighboring Bitwise XOR: Valid Binary Array Existence

The XOR of all elements in derived must equal 0 for a valid original array to exist. If the result is 0, return true; otherwise, return false.

A 0-indexed array derived with length n is derived by computing the bitwise XOR (⊕) of adjacent values in a binary array original of length n.
Specifically, for each index i in the range [0, n - 1]:

If i = n - 1, then derived[i] = original[i] ⊕ original[0].
Otherwise, derived[i] = original[i] ⊕ original[i + 1].

Given an array derived, your task is to determine whether there exists a valid binary array original that could have formed derived.
Return true if such an array exists or false otherwise.
