- Create a class “Node” which is a single node of a singly linked list. The node stores an integer datatype. The class has two data members, an integer and pointer to the same Node class. Implement the following methods:1. The default constructor: Set value of the data member to zero2. A parameterized constructor: Node(int a); takes an integer variable and assigns it to the data member of this object. Set next pointer to NULL.3. Node* GetNextPointer() const; Retun next pointer of this Node4. void SetNextPointer(Node *ptr); Set the next pointer of this node to the ptr that is passed to the function.5. void SetData(int a); Set data of this node equal to ‘a’6. int GetData() const; returns the data of this object.The data member are private whereas the methods are public.Create a class “Node” which is a single node of a singly linked list.

- Write a Python Code for the given constructor and conditions: Given Constructor: def __init__ (self, a) Pre-condition: Array cannot be empty. Post-condition: This is the default constructor of MyList class. This constructor creates a list from an array.Create a node class named LinkedNodes that uses up to 4 dynamic pointers to connect it to the other 8 nodes in the structure (a total of 9). The data in each node will be a unique integer number from 1 through 9. Include in your class definition these functions at a minimum: getVal(), setVal(), getNext(), setNext(), getPrev(), setPrev(), constructor(s) and destructor. Write a simple program to load these nodes into a linked structure. Do not use an array, the pointers will do that for you. You should be able to reach any node from any other node in the structure by traversing a maximum of 2 nodes from the current one. The output from your program should report the traversals between all nodes in the structure, starting with the node whose value is one. (See the example below) Node 1 2 3 4 5 6 7 8 9 -> Traverses to Node 1 Node 2 1->2 2->6->1 3->6->1 3->7->2 4->6->1 4->7->2 4->8->3 5->6->1 5->7->2 5->8->3 6->1->2 6->1->3 7->1->3 8->3 6->1 7->1 8->1 9->1 Node 3 1->3 2->3 7->2 8->2 9->2…Java Objects and Linked Data: Select all of the following statements that are true. The Java Class Library's class ArrayList implements the LinkedList interface. In Java, when one reference variable is assigned to another reference variable, both references then refer to the same object. In Java, the "equals"-method that any object inherits can be overwritten to compare objects field by field.
- TaskDeclare and implement 5 classes: FloatArray, SortedArray,FrontArray, PositiveArray & NegativeArray.1- The FloatArray class stores a dynamic array of floats and itssize. It has:- A parameterized constructor that takes the array size.- An add method that adds a float at the end of the array.- Overloading for the insertion operator << to write the array to afile (ofstream)- Overloading for the extraction operator >> to read the arrayelements from the file (ifstream) and add them to the array.- A destructor to deallocate the array2- The SortedArray inherits from FloatArray. It has:- A parameterized constructor that takes the array size.- An add method that adds a float at the right place in the arraysuch that the array remains sorted with every add. Don’t add tothe array then sort but rather add in the right place.3- The FrontArray inherits from FloatArray. It has:- A parameterized constructor that takes the array size.- An add method that adds a float at the front of…The two classes you will create will implement the operations defined in the interface as shown in the UML class diagram above. In addition, BinarySearchArray will implement a static method testBinarySearchArray() that populates the lists, and lets the user interactively test the two classes by adding and removing elements. The parameter BinarySearch can represent either class and tells testBinarySearchArray which class to test. Steps to Implement: 1) To get started create a new project in IntelliJ called BinarySearch. Add a class to your project called BinarySearchArray. Then add another class BinarySearchArrayList and an interface called BinarySearch. The interface BinarySearch includes public method stubs as shown in the diagram. You are allowed to add BinarySearchArrayList to the same file as BinarySearch but don't add an access modifier to this class, or for easier reading, you can declare the classes in separate files with public access modifiers. Only the class…Answer for.Write a Python Code for the given constructor and conditions: Given Constructor: def __init__ (self, a) Pre-condition: Array cannot be empty.

Sample InputHi hello hi good bye goodbye Bye bye good say Sample OutputBye Hi bye hello hi say The input.txt file is found along with the zip folder where this instructions file also came along with. Note: you are not allowed to use pythonic lists, and its methods and functions, and string methods. However the use of the file handling methods (read readlines and readline) are allowed for this project.
