# The original implementation has a time complexity of O(n), where n is the length of the input list nums.
# This is because each number in nums is checked against the set of seen numbers, which has an average time complexity of O(1) using hash-based set implementation.
# The implementation is already quite efficient, and there is not much room for performance improvement. However, we can make a small modification to potentially improve the average case performance.
# Revised implementation:
