- What the code is about: Implement a recursive algorithm to add all the elements of a non-dummy headed singly linked linear list. Only head of the list will be given as parameter where you may assume every node can contain only integer as its element.Note: you’ll need a Singly Node class for this code. **PLEASE EXPLAIN HOW THE NODE CLASS AND THE CONSTRUCTOR OF THE NODE CLASS IS WORKING IN THIS CODE** #singlty node class for single linked listclass node: def __init__(self, value = None, next=None): self.value = value self.next = nextdef AddAll(head):#takes head of single linked list head if head==None: return 0#if reached end of the linked list return AddAll(head.next) + head.value #each node's next pointer is passed in recursive call #and value of each node is added while returning from recursive callwrite a code to Find the minimum node of a BST. Use either recursive or non-recursive approach.Consider the following function:int mystery(NodeInt32* node){int counter = 0; while (node != NULL) {counter++;node = node->next; } return counter;}(a)The mystery function is recursive.A. True B. False
- The implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.This is java recursive code --> I only need this method. please help Write a RECURSIVE method “int sumPos(Node head)” to calculate the sum of positive integers in a linked list of integers referenced by head. No global variables are allowed. Node is declared as: Node { int value; Node next; }The program BinaryTreeTest.java prints the nodes by inorder traversal. Please add two methods printPreOrder(Node node) and printPostOrder(Node node) in the program and print the numbers by the two orders. Then please add findMax(Node node)and findMin(Node node) to find the maximal and minimal numbers respectively for the tree. Hint: to implement findMax(Node node), a recursive method is needed. If the node is empty. return 0. If the node's right sub-tree is null, return the node's value. Otherwise call findMax() recursively using the right child as the parameter. findMin(Node node) is similar, but you will focus on left child.
- Write the recursive method for adding a node in a linked list.Given a singly linked list, print reverse of it using a recursive function printLinkedList( node *first ) where first is the pointer pointing to the first data node. For example, if the given linked list is 1->2->3->4, then output should be: 4 3 2 1 (note the whitespace in between each data value)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…
- public int insert(int value);/* Creates a node with the parameter as its value* and inserts the node into the tree in the appropriate position.* This method should call upon the recursive insert_r() helper method* you write.** we will make the assumption for this assignment (and implement it so) * that the values in a BST are unique... no duplicates** If we insert a value and it succeeded... adds it to the tree* return the element that was added** If we try to add an element and it is a duplicate, return the element* but make no changes to the tree... no new nodes added** @param int value to be inserted in tree* @return integer that was insrted after insertion is done.** Example 1: Suppose we have the tree below:** (27)* / \* (4) (29)* / \* (1) (8)* After calling insert(5), we'd obtain the following tree:** (27)* / \* (4) (29)* / \* (1) (8)* /* (5)** Example 2: Suppose we have the tree below:** (87)* / \* (42) (128)* \ \* (46) (145)* /* (44)** After calling insert(147), we'd obtain the…Create a lazy elimination deletion function for the AVLTree class.There are several approaches you can take, but one of the simplest is to add a Boolean property to the Node class that indicates whether or not the node is designated for deletion. This variable must then be considered by your other techniques.a. Write the recursive method for adding a node in a linked list. b.
