Array
Bit Manipulation
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]:
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.
Input: derived = [1,1]
Output: true
Explanation: A valid original array that gives derived is [0,1].
derived[0] = original[0] ⊕ original[1] = 1
derived[1] = original[1] ⊕ original[0] = 1
Example 3
Input: derived = [1,0]
Output: false
Explanation: There is no valid original array that gives derived.
Constraints
n == derived.length
1 <= n <= 105
The values in derived are either 0's or 1's
