Thank you. This algorithm is super efficient. Why do I still use crappy algorithms like merge sort and quick sort? I could be using this brilliant algorithm designed by the great Albert Einstein himself instead. I wish you luck in your endeavors. Remember to continue sorting in O((n+1)!) time. n log n is sooo overrated.
