Homework Answers
The above sorting is quick sort.
Quick sort is fastest algorithm.
The technique of quick sort is split the array into 3 parts those are
- Pivot
- Left
- Right
Comparision of left and right change the pivot after successful comparision operation.
In this the operation done on the subarray from a[lo] to a[hi].
The time complexity is reduced in this sorting technique.

Modify the sorts (selection sort, insertion sort, bubble sort, quick sort, and merge sort) by adding code to each to tally the total number of comparisons and total execution time of each algorithm. Execute the sort algorithms against the same list, recording information for the total number of comparisons and total execution time for each algorithm. Try several different lists, including at least one that is already in sorted order. ---------------------------------------------------------------------------------------------------------------- /** * Sorting demonstrates sorting and searching on an...

must provide the following public interface: public static void insertSort(int [] arr); public static void selectSort(int [] arr); public static void quickSort(int [] arr); public static void mergeSort(int [] arr); The quick sort and merge sort must be implemented by using recursive thinking. So the students may provide the following private static methods: //merge method //merge two sorted portions of given array arr, namely, from start to middle //and from middle + 1 to end into one sorted portion, namely,...

Sort a queue in java with generic type, below is my approach
which has some issues. The porpose is to implement a method to sort
the elements of the queue in ascending order, but I am not sure how
to deal with generic type T instead of int or string. Need your
help to solve this problem. Please post the correct code and the
idea, thanks!
