Program Plan Intro

Sorting:

Sorting is a process where the elements of a list are arranged in a particular order. The order of the list can be either present in the ascending order or descending order.

Quick sort:

  • The algorithm works by selecting a pivot element from the array.
  • The array is being divided into two parts such that the element present at the first part of the array will be less than pivot and the elements that are present at the second part of the array are greater than the pivot element.
  • The process is made in recursive way to the first half and second half of the list until the complete list is sorted.

Write a program that benchmarks QuickSort and InsertionSort. You should use at least 5 different data sets and record the performance of each algorithm on the same sets under the same conditions. Write a short report that compares the two algorithms based your results. It is important to include a discussion of the initial states of the data sets in your report. language Java public class week3 {public static void main(String args[]){ //========================================================== //Question 1 testing //================== // Comment on benchmarking for Q1 results // // //========================================================== } static void quickSort(int f[], int p, int q){ if(q-p <= 1) ; //skip else{ int x; int i, j, k; // let x = middle element in f[p..q-1] x = f[(p+q)/2]; //x = f[p]; i = p; j = p; k = q; while(j != k){ if(f[j] == x) j = j + 1; else if(f[j] < x){ //swap f[j] with f[i] int temp; temp = f[j]; f[j] = f[i]; f[i] = temp; j = j + 1; i = i + 1; } else{…
Implement two different versions of quicksort in a high level programming language. The first version will use the first element of the array as the pivot. The second version will use the median of the first element, middle element, and last element of the array as the pivot. For each version, compare the performance on random arrays of data of sizes 10n for n = 2, 3, and 4. Create three graphs (one for the random data, one for the increasing data, and one for the decreasing data) to illustrate your results. Discuss these results.
The following are the operations that you can do using a single linked list. Choose only one operation then create the algorithm and simulate. The attached Rubric will be used in evaluating the activity.    1.    Delete a particular node in a single linked list 2.    Delete the first node of a single linked list 3.    Insertion after a given node of a single linked list 4.    Insertion at a given position in a single linked list 5.    Insertion before a given node in a single linked list 6.    Reverse a single linked list   EX:    Delete the last node of a single linked list Problem" Deletion of the last node in a single linked list   Algorithm"     Step 1: if HEAD = NULL            Write UNDERFLOW                Go to Step 8 Step 2: SET PTR = HEAD             Step 3: Repeat Steps 4 and while PTR à NEXT = NULL           Step 4: SET PREPPTR = PTR   Step 5: SET PTR =PTR à NEXT [End of loop]   Step 6: SET PREPTR à NEXT = NULL   Step 7: FREE PTR   Step 8: EXIT…
