Leetcode Problem 1734. Decode XORed Permutation

1734. Decode XORed Permutation

Leetcode Solutions

Decoding with XOR and Accumulation

  1. Initialize a variable totalXor to 0.
  2. XOR totalXor with all numbers from 1 to n (inclusive).
  3. Initialize a variable oddXor to 0.
  4. XOR oddXor with every odd-indexed element in the encoded array.
  5. The first element of perm is the XOR of totalXor and oddXor.
  6. Initialize the perm array with the first element.
  7. Iterate through the encoded array, decoding each subsequent element of perm by XORing the previous element with the current element in encoded.
  8. Return the perm array.
