Assume a Node class has been defined using the Node class implementation in your textbook, except that the data members have been declared public instead of private. This means that the code shown below has direct access to the data members defined inside the Node class. Type the exact output produced by the following code fragment. Assume that the code compiles and executes without errors. void linkedList (void) { Node<char> *ptr1; Node<char> *ptr2; Node<char> *top; char ch; ptr1 = new Node<char>; top = ptr1; ptr1->item = 'D'; ptr1 = new Node<char>; top->next = ptr1; ptr1->item = 'E'; for (ch = 'H'; ch < 'P'; ch = ch + 3) { ptr2 = new Node<char>; ptr1->next = ptr2; ptr2->item = ch; ptr1 = ptr1->next; ptr2 = new Node<char>; ptr1->next = ptr2; ptr2->item = ch + 1; ptr1 =…
Tree Define a class called TreeNode containing three data fields: element, left and right. The element is a generic type. Create constructors, setters and getters as appropriate. Define a class called BinaryTree containing two data fields: root and numberElement. Create constructors, setters and getters as appropriate. Define a method balanceCheck to check if a tree is balanced. A tree being balanced means that the balance factor is -1, 0, or 1.

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. part 4 5 and 6 In c++.
