Edit the Person.java file so that the natural ordering or a Person is by last name in ascending order. Use the merge sort algorithm to implement the MergeSort sort method. import java.util.ArrayList; import java.util.List; public class Main { public static void main(String[] args) { List<Person> people = new ArrayList<>(); people.add(new Person("Frank", "Denton", 73)); people.add(new Person("Mark", "Cohen", 44)); people.add(new Person("Tim", "Smith", 22)); people.add(new Person("Steve", "Denton", 16)); people.add(new Person("Andy", "Ashton", 44)); people.add(new Person("Albert", "Denton", 58)); System.out.println("Before: " + people); List<Person> result = MergeSort.sort(people); System.out.println("After: " + result); } } import java.util.Collections; import java.util.List; public class MergeSort { public static List<Person> sort(List<Person> people) {…
A list of n dates of birth (specified in the format 17801229) should be sorted. Assume that n is a large number (> 400) and that there may be duplicates. Which of the following algorithms is most suitable to choose? Countingsort Heapsort Mergesort Quicksort Insertionsort Radixsort
A gap sort is a version of the bubble sort method that compares items that are some number i places away, where i is an integer smaller than n, rather than neighbouring elements each time across the list. For example, the first element would be compared to the (i + 1) element, the second element to the (i + 2) element, the nth element to the (n - i) element, and so on. When all of the items that may be compared have been compared, a single iteration is accomplished. On the following iteration, i is reduced by a value bigger than one, and the procedure is repeated until i is less than one. Utilise a gap kind.
Create a list of N random numbers (Integer) and put them into a list and sort the list using the List’s sort method. Randomly select a number from the list. Find the position of the number in the list using binary search and record the number of comparison that you have to make (c). Then plot c against N for N = 30, 50, 75, 100, 150, 200, 300, 400, and 500. Implement the KMP algorithm from scratch. Test it and plot c against n and m where n is the size of the text and m is the size of the pattern, for different values of n and m. Implement the Boyer Moore algorithm from scratch. Test it and plot c against n and m where n is the size of the text and m is the size of the pattern, for different values of n and m. Implement the Z algorithm from scratch. Test it and plot c against n and m where n is the size of the text and m is the size of the pattern, for different values of n and m.
In the Selection Sort JAVA, please write the swap method without writing int i, and j into the method. Initialize it somewhere else by not changing this code please! public class SelectionSort {public static void main(String[] args) {int[] intarray = {20, 35, -15, 7, 55, 1, -22};for(int lastUnsorted = intarray.length-1;lastUnsorted > 0;lastUnsorted--){// if largest is in 0th index// we start from the 1st index// if 1st is greater than it, swap the elementint largest=0;for(int i=1; i<=lastUnsorted; i++){if(intarray[i] > intarray[largest]){largest = i;}}swap(intarray, largest, lastUnsorted);}for(int i=0; i<intarray.length; i++){System.out.println(intarray[i]);}}public static void swap(int[] array, int i, int j){if(i == j){return;}int temp = array[i];array[i] = array[j];array[j] = temp;}}
A sml binarySearch function that recursively implements the binary search algorithm to search a sorted integer list for a specified integer and returns true if it is found, false otherwise. For example, binarySearch ([100,200,300,400,500], 200) returns true, whereas binarySearch([100,200,300,400,500], 299) returns false. Hint: Write a helper function mid that returns a tuple (index, value) representing the middle value in a list. For example, mid [10, 2, 40, 8, 22] returns (2,40) because the value 40 at index 2 is the middle value in the list. Similarly, mid [10, 20] would return (1, 20). Use mid in conjunction with slice to implement binarySearch.
Implement two out of three of the basic sorting algorithms - Bubble Sort, Selection Sort, and Insertion Sort - in a generic List. Initial code to be completed: #include <iostream>#include "linkedlist.h" void bubbleSort(List*);void selectionSort(List*);void insertionSort(List*); /** * This activity is focused on using Arrays and Linked Lists as two different * implementations of List. It follows that you are only to use the methods of * List and not of the specific array or linkedlist. */int main(void) { // WARNING! Do not modify main method! // Doing so will nullify your score for this activity. char li; cin >> li; List* list; if (li == 'A') { list = new ArrayList(); } else { list = new LinkedList(); } int length; cin >> length; int input; for (int i = 0; i < length; i++) { cin >> input; list->add(input); } char sym; cin >> sym; int arg1; switch (sym) {…
Let L={x1,x2,…,xn} be a list of n elements. Let us search for a key K in the list L. If the key is presented in the list L at index(or position) j then partition the list L into disjoint lists L1 and L2 such that L1={x[i]:x[i]εL such that i≤j} and L2={x[i]:x[i]εL such that i>j}. If the key is not present in the list output is “no”. Write an algorithm (using single linked list) and subsequent C program for your algorithm to compute lists L1 and L2 for the given list L and key K. Note: Don’t use any inbuilt functions in your program. Example1: If L={16, 15, 1, 27, 19, 100, 200,3} and key k= 27 then L1={16, 15,1,27} and L2={19, 100,200, 3}. Example 2: If L={16, 15, 1, 27, 19, 100, 200,3} and key k= 127 then no.
Implement a list of employees using a dynamic array of strings.Your solution should include functions for printing list, inserting and removingemployees, and sorting lists (use Bubble sort in C++ language).Keep list of employees sorted within the list after insertion.See the following example:How many employees do you expect to have?5 (Carriage Return)Menu :1 . Print full list of employees2 . Insert new employee3 . Remove employee from list0 . Exit2 (Carriage Return)Input name of new employee : MikeMenu :1 . Print full list of employees2 . Insert new employee3 . Remove employee from list0 . Exit1(Carriage Return)1 . MaryMenu :1 . Print full list of employees2 . Insert new employee3 . Remove employee from list0 . Exit
Alter insertion sort below to sort a list of strings instead of numbers. It shouldn't return anything - it should sort the list "in place". The sorting should ignore case. For example "Zebra" should come after "apple", "maRker" should come after "marble", etc. Name this function string_sort. After calling this function, the list that was passed in should now contain the exact same strings it did before, but in sorted order. def insertion_sort(a_list): """ Sorts a_list in ascending order """ for index in range(1, len(a_list)): value = a_list[index] pos = index - 1 while pos >= 0 and a_list[pos] > value: a_list[pos + 1] = a_list[pos] pos -= 1 a_list[pos + 1] = value

There is a variation of the bubble sort algorithm called a gap sort that, rather than comparing neighboring elements each time through the list, compares elements that are some number i positions apart, where i is an integer less than n. For example, the first element would be compared to the (i + 1) element, the second element would be compared to the (i + 2) element, the nth element would be compared to the (n - i) element, and so on. A single iteration is completed when all of the elements that can be compared, have been compared. On thenext iteration, i is reduced by some number greater than 1 and the process continues until i is less than 1. Implement a gap sort.
