- Sorting objects in the real world https://docs.oracle.com/javase/8/docs/api/java/util/LinkedList.html There are 5000 people living in the town. Every day they have new COVID-19 cases. When people show symptom, they go to the hospital and put themselves in the waiting list for testing. A new person is added at the end of the list. Due to the lack of testing kit, all in the list cannot be tested. Hospital has to sort them and select a few. Since the elderly is very weak to the COVID-19, every midnight the doctors sort the people in the list by their age to decide who is taking the test for the next day depending on the availability of testing kit. Input to the program has the form where the first line indicates how many days they will do the operation. For each day, the input starts with the day number, along with the following patient list where each element represents the name of patients and the age. The input ends with the number of available testing kits. The output display, at…In Java!!!. Design and implement a recursive version of a binary search. For the recursive version, instead of using a loop to repeatedly loop for the target value, allow each call to a recursive method check one value. If the value is not the target, refine the search space and call the method again. The indexes that define the range of viable candidates can be passed to the method. The base case is either finding the target value or running out of data to search. Design the program to work for on an array of sorted String objects.Create a client that produces test data by distributing objects in a manner different than uniformly, such as the following: ■ Gaussian■ Poisson■ Geometric■ Discrete Create and test assumptions about how the performance of the algorithms will be impacted by such input.
- A binary search algorithm on an array of N elements have an average complexity in the order of? A. Nlog2N B. log2N C. N-1 D.2N Justify your answer with explanations Modifying software to respond to changes in its environment is called? A. Adaptive maintenance B. Corrective maintenance C. Pre-emptive maintenance D. Preventive maintenance Justify your answer with explanationsImplement a city database using ordered lists. Each database record contains the name of the city (a string of arbitrary length) and the coordinates of the city expressed as integer x and y coordinates. Your database should allow records to be inserted, deleted by name, and searched by name. Another operation that should be supported is to print all records within a given distance of a specified point/coordinate. The order of cities should be alphabetically by city name. Implement the database using: an array- based list implementation. By using JAVA.Implement solutions for the following methods: • getCourseSize() – returns the number of students registered in the course (not in the waitlist). It should maintain the public size variable that keeps track of the number of students registered. • getRegisteredIDs() – returns an array of int[], namely registered student id’s. The length of the array is the size (number of students) in the course. • getRegisteredStudents() – returns an array of type Student[], namely the registered Students. The length of the array is the current size (number of students) of the course. • getWaitlistedIDs() – returns an array of type int[], namely the ids of students in the waitlist. • getWaitlistedStudents() – returns an array of Students in the waitlist. public class Course { public String code; public int capacity; public SLinkedList<Student>[] studentTable; public int size; public SLinkedList<Student> waitlist; public Course(String code) {…
- Create four methods named insertionSort(), bubblesort(), mergesort() and quicksort(). Implement the sorting algorithms in the corresponding methods. In the main method, create four arrays a, b, c, d and initialize them with the same values. Pass these four arrays in four different functions. Create four instance variables named insertionSwap, bubbleSwap, countMerge, and countQuickSort and initialize them to 0. In methods insertionSort(), bubblesort() and quicksort(), increment the variables insertionSwap, bubbleSwap, and countQuickSort respectively by one whenever they call the method swap(). In method mergesort(), increment the variable countMerge by one to count the swaps. Use method swap() to swap the values.Your tasks Implement the functions marked with ??? in withProb.scala. （as shown in below） package withProb: /** * NOTE: The seed should be System.nanoTime or something similar * in order to get real pseudo-randomness but we fix it now * for the sake of repeatability. */ val rand = new scala.util.Random(2105) /** * Executes the given code with probability "prob". * For instance, * doWithProb(30.0) { Console.println("I'm feeling lucky!") } * shall print the text to the console with probability of 30 percent. * * Note that you have to modify the type of the "thenAction" parameter so that it admits code * to be passed in "call-by-name" evaluation mode. * Please see the course material and * http://docs.scala-lang.org/tour/automatic-closures.html */ def doWithProb(prob: Double)(thenAction: Unit): Unit = require(0.0 <= prob && prob <= 100.0) ??? end doWithProb /** * The expression * withProb(prob)…Retrieving a value using its associated key can be accomplished using anindexer, which works just like an indexer for an array. A key is passed in asthe index value, and the value associated with the key is returned, unless thekey doesn’t exist, in which a null is returned.Write short code segment demonstrates how this technique works:
- You are in the process of choosing between two 3rd party libraries that implement some algorithm and have found two solutions, A and B, that are advertised as O(n) and ~n, respectively. Which of these solutions would you prefer in terms of performance? Explain. (Hint: think about which one gives a more "stable" result.)Implement a recursive function void deleteMax() on the IntList class (provided). The function will delete from the IntList the IntNode containing the largest value. If there are multiple nodes containing this largest value, only delete the 1st one. Be careful not to cause any memory leaks or dangling pointers. You may NOT use any kind of loop (must use recursion). You may NOT use global or static variables. You may NOT use any standard library functions. Ex: list: 5->7->1->16->4->16->3 list.deleteMax(); list: 5->7->1->4->16->3 IntList.h #ifndef __INTLIST_H__#define __INTLIST_H__ #include <ostream> using namespace std; struct IntNode {int value;IntNode *next;IntNode(int value) : value(value), next(nullptr) {}}; class IntList { private:IntNode *head; public: /* Initializes an empty list.*/IntList() : head(nullptr) {} /* Inserts a data value to the front of the list.*/void push_front(int val) {if (!head) {head = new IntNode(val);} else {IntNode…t for several problems you will modify some provided Python code to implement algorithms to solve the same instance of the knapsack problem. After implementing all of the code and solving the problem, you must provide a single table of all results similar to the following: Table 1: Example of results summary (numbers are not realistic) Algorithm Iterations Items Selected Weight Objective Local Search (Best Improvement) 3102 49 97 117 Local Search with Random Restarts (k = 100) Local Search with Random walk (p = 0.25) 9510 121 21 147 2102 87 32 184 etc. Knapsack Problem Definition Given n different items, where each item i has an assigned value (v.) and weight (w), select a combination of the items to maximize the total value without exceeding the weight limitations, W, of the knapsack. IMPORTANT!: When generating random problem instance set you must use the code provided and values: n = 150; max weight of 2500; and, use a seed value (for the random number generator) of 51132023.
