- please code in python Forbidden concepts: recursion, custom classes Create a program for a used car dealership that buys and sells cars. The dealership currently has an S14, 240z, R33, and a 350z. The program must keep track of inventory. There must be options to add, remove, or print the list of cars, along with a killswitch.in C++... kth Element Extend the class linkedListType by adding the following operations:a. Write a function that returns the info of the kth element of the linked list. If no such element exists, terminate the program.b. Write a function that deletes the kth element of the linked list. If no such element exists, terminate the program. Provide the definitions of these functions in the class linkedListType. PLEASE DON'T reject this question, this is the whole question that I have... so please do it however u can, Thank you!Tour.java Create a Tour data type that represents the sequence of points visited in a TSP tour. Represent the tour as a circular linked list of nodes, one for each point in the tour. Each Node contains two references: one to the associated Point and the other to the next Node in the tour. Each constructor must take constant time. All instance methods must take time linear (or better) in the number of points currently in the tour. To represent a node, within Tour.java, define a nested class Node: private class Node { private Point p; private Node next; } Your Tour data type must implement the following API. You must not add public methods to the API; however, you may add private instance variables or methods (which are only accessible in the class in which they are declared). public class Tour // Creates an empty tour. public Tour() // Creates the 4-point tour a→b→c→d→a (for debugging). public Tour(Point a, Point b, Point c, Point d) // Returns the number of points in this tour. public…
- Add the following functions and write a program to test these functions in the class linkedListType: a. Write the definition of a function that returns the data of the kth element of the linked list. If such element is not exist in the list, exit the program. b. Write the definition of a function that deletes the kth element of the linked list. If such element is not exist in the list, exit the program and display message as output. (Subject:Data stracture and algorithm )Write JAVA code General Problem Description: It is desired to develop a directory application based on the use of a double-linked list data structure, in which students are kept in order according to their student number. In this context, write the Java codes that will meet the requirements given in detail below. Requirements: Create a class named Student to represent students. In the Student class; student number, name and surname and phone numbers for communication are kept. Student's multiple phones number (multiple mobile phones, home phones, etc.) so phone numbers information will be stored in an “ArrayList”. In the Student class; parameterless, taking all parameters and It is sufficient to have 3 constructor methods, including a copy constructor, get/set methods and toString.Please write in C display Pages 10. Write function display Pages to do the following a. Return type void b. Parameter list includes i. Parameter that contains the page number, data type integer (i.e., page)ii. One-dimensional array, data type integer, that stores the page allocations (i.e., allocation) c. Display to the console the page number d. Write a looping construct to iterate through the frames (i.e.. FRAMES) i. Display to the console the memory block assigned based on the following logic 1. If the value stored at the current index of array allocation is -1 (ie., INVALID), output a dash (i.e., *-*) 2. Else, output the allocation at the current index of array allocation
- Write Java code Objectives •Use an abstract data type for a list •Use a method that contains an Object type as a formal parameter •Use methods in an existing class •Access data members within a class Required Files: •ListInterface.java •ListException.java •ListOutOfBoundsException.java •ListArrayBased.java Description A list is an abstract data type used to store ordered data, and contains operations that fall into the following categories: (1) add data to a data collection, (2) remove data from a data collection, and (3) ask questions about data in a data collection. The operations which ask questions about the data in a data collection may include operations that determine if a data collection is empty, determine the size of a data collection, and retrieve the item at a given position in a data collection. A list should be able to contain any type of object. The methods for the List support any object as specified in the interface. In this assignment, the objects will be S trings.…i) Create a Node class which will hold two fields i.e an integer element and a reference to the next Node. ii) Create a Linked list Abstract Data Type (ADT)named MyList.The elements in the list are Nodes consisting of an integer type key (all keys are unique) and a reference to the next node. [You are not allowed to use any global variable other than head] If you are using PYTHON, make sure your code has the methods invoked through test statements and proper printing statements according to the tasks. You may create a separate Tester class for this or test the methods within the MyList class. Write a code in pythoni) Create a Node class which will hold two fields i.e an integer element and a reference to the next Node. ii) Create a Linked list Abstract Data Type (ADT)named MyList.The elements in the list are Nodes consisting of an integer type key (all keys are unique) and a reference to the next node. Use Python Language.
- for c++ A set is a collection of distinct elements of the same type. Design the class unorderedSetType. Design the class unorderedSetType, derived from the class unorderedArrayListType, to manipulate sets. Note that you need to redefine only the functions insertAt, insertEnd, and replaceAt. If the item to be inserted is already in the list, the functions insertAt and insertEnd output an appropriate message. Similarly, if the item to be replaced is already in the list, the function replaceAt outputs an appropriate message. Write a program to test your class.In java: Create a Data Class.In this problem you will create a class named Data that can contain any information needed for they individual problems to come. This class may be empty or can contain as many methods or instance variable as you see fit for the problem. 2.In java: Create a Linked List Class; Each node of this linked list must contain a Data object from problem 1. Should contain: Head, Tail, Doubly linked nodes containing data objects You may reuse this Linked List or the Node for several problems or create new elements that operate similar you feel fit the problem space better. 3. in java: Create a Stack class; Each node of this stack must contain a Data object from problem 1. In this stack there must be an array to represent items in the stack up until a set size, AS WELL AS a linked list for overow that can take in nodes bast the maximum size of the array; If both data structures aren't present you will only. The class should also come with the following methods:…Write a Python code for the given functions and definitions: Task1 Given function: def isEmpty(self) Pre-condition: None. Post-condition: Returns true if a list is empty. Otherwise, returns false. Task2 Given function: def clear(self) Pre-condition: The list is not empty. Post-condition: Removes all the elements from a list.
