Give an efficient algorithm to compute the union of sets A and B, where n = max(|A|, |B|). The output should be an array of distinct elements that form the union of the sets, such that they appear exactly once in the union. Assume that A and B are unsorted. Give an O(n log n) time algorithm for the problem.
