# Approach 3: Two Pointers

# Time Complexity: O(n log n)
# Complexity analysis:
# Time Complexity: O(nlogn + mlogm), where n and m are the lengths of the arrays. We sort two arrays independently and then do a linear scan.
# Space Complexity: from O(logn+logm) to O(n+m), depending on the implementation of the sorting algorithm.
