Leetcode Problem 1707. Maximum XOR With an Element From Array

1707. Maximum XOR With an Element From Array

Leetcode Solutions

Trie with Sorting and Two-Pointers Approach

  1. Sort the nums array in ascending order.
  2. Sort the queries array based on the second element mi of each query and keep track of the original indices.
  3. Initialize a Trie data structure to store binary representations of numbers.
  4. Initialize two pointers: one for the nums array (j) and one for the queries array (i).
  5. For each query, add elements from nums to the Trie that are less than or equal to mi using the j pointer.
  6. Query the Trie with xi to find the maximum XOR value and store it in the result array at the original index of the query.
  7. Return the result array after processing all queries.
