1310. XOR Queries of a Subarray

Leetcode Solutions

Prefix XOR Approach

  1. Initialize an array prefixXOR with the same length as arr plus one, and set the first element to 0.
  2. Compute the prefix XOR array by iterating through arr and setting prefixXOR[i+1] to prefixXOR[i] XOR arr[i].
  3. Initialize an empty list result to store the XOR results for each query.
  4. For each query [left, right] in queries, compute the XOR for the range by XORing prefixXOR[left] and prefixXOR[right + 1], and append the result to result.
  5. Return the result list.
