How can the quicksort algorithm be implemented with a 3-way partition in Java?

Answer 1

To implement the quicksort algorithm with a 3-way partition in Java, you can modify the partitioning step to divide the array into three parts instead of two. This involves selecting a pivot element and rearranging the elements so that all elements less than the pivot are on the left, all elements equal to the pivot are in the middle, and all elements greater than the pivot are on the right. This approach can help improve the efficiency of the quicksort algorithm for arrays with many duplicate elements.
