I have read before that Hoare Partitioning is faster by a constant factor than the Lomuto Partitioning. This will clearly have an important impact on the performance of Quick Sort. Here, I wanted to check that and see if it holds true in practice, and if so, what that constant factor might be. Let's define the two partitioning schemes below:
Quicksort is a remarkably flexible algorithm with several variations. Here, I wanted to write about the Hoare partitioning method, in particular, about the special choice of its pivot as the leftmost element. First, lets quickly write down the partitioning algorithm from CLRS exercise 7.1.
