2433. Find The Original Array of Prefix Xor

Leetcode Solutions

Using XOR Properties to Reconstruct Original Array

  1. Initialize an empty array arr of size n (the same size as pref).
  2. Set arr[0] to pref[0] since the first element of arr is the same as the first element of pref.
  3. Iterate over the indices from 1 to n - 1: a. Calculate arr[i] by XORing pref[i] with pref[i - 1].
  4. Return the reconstructed array arr.
