The Quicksort algorithm works by
A) repeatedly comparing adjacent items and swapping them so smaller values come before larger values
B) repeatedly locating the smallest value in the unsorted portion of the array and moving it toward the lower end of the array
C) repeatedly taking the first value in the unsorted portion of the array and placing it at its proper place in the part of the array that is already sorted
D) partitioning the unsorted portion of the array into two sublists and a pivot and recursively sorting the two sublists

The Quicksort algorithm works by partitioning the unsorted portion of the array into two sublists and a pivot, and recursively sorting the two sublists. This is done by selecting a pivot element and partitioning the other elements into two sublists, according to whether they are less than or greater than the pivot. The process is then repeated on the two sublists until the entire array is sorted. This approach has an average time complexity of O(n log n), making it an efficient sorting algorithm for large datasets.
