Implement Quick Sort in Java.
*QuickSort: Quicksort or partition-exchange sort, is a fast sorting algorithm, which is using divide and conquer algorithm. Quick sort first divides a large list into two smaller sub-lists: the low elements and the high elements. Quick sort can then recursively sort the sub-lists. Steps to implement Quick sort: 1) Choose an element, called pivot, from the list. Generally pivot can be the middle index element or u can choose any. 2) Reorder the list so that all elements with values less than the pivot come before the pivot, while all elements with values greater than the pivot come after it (equal values can go either way). After this partitioning, the pivot is in its final position. This is called the partition operation. 3) Recursively apply the above steps to the sub-list of elements with smaller values and separately the sub-list of elements with greater values. //Write a Java program to implement quick sort algorithm. public clas...
