1734. Decode XORed Permutation

There is an integer array perm that is a permutation of the first n positive integers, where n is always odd. It was encoded into another integer array encoded of length n - 1, such that encoded[i] = perm[i] XOR perm[i + 1]. For example, if perm = [1,3,2], then encoded = [2,1]. Given the encoded array, return the original array perm. It is guaranteed that the answer exists and is unique. Exam
