- Attached is a C program traveselter.c. This is a solution to the problem of constructing a binary tree from the inorder and preorder listing of the nodes. It has the recursive function void list_inorder(struct Node * root) which lists the nodes of the tree in-order. Rewrite this function so that it is iterative. Hint: Implement a stack and you may assume it can hold a maximum of 100 items. You have to decide what will be in an item of the stack, and design a structure for it. I suggest that one member of an item is a pointer to a tree node. #include <stdlib.h> #include <stdio.h> struct Node { int val; struct Node * left; struct Node * right; }; struct Node * create_node(char val); void destroy_node(struct Node * root); void destroy_tree(struct Node * root); void list_preorder(struct Node * root); struct Node * create_tree(char pre_order[], int pre_first, int pre_last, char in_order[], int in_first, int in_last); void list_inorder(struct Node *…For c++ programming languge: How many comparisons are required in an array of 16 elements, if quicksort always chooses the largest element as pivot? What is the depth of the recursion tree?Write a recursive function, OnlyChild(..), that returns the number of nodes in a binary tree that has only one child. Consider binaryTrecNode structure is defined as the following. struct binaryTreeNode int info; binaryTreeNode *llink; binaryTreeNode *rlink; The function is declared as the following. You ust write the function as a recursive function. You will not get any credits if a non-recursive solution is used. int OnlyChild(binaryTreeNode *p); For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac). B IUS Paragraph Arial 10pt 11
- I am to write a python function that receives the root of a binary tree (t) and returns a list of all the nodes up to a specific node (k). the funcion must use recursion Starting code: def path_to_k(t,k): return [t.key]PLEASE WRITE IN C++ Implement a program that uses an array based binary tree (sequential tree) that has a menu with these options: 1.) insert (This option asks the user for a size and then creates the array based tree, filling the tree with characters or integers . Fill the sequential tree as a complete tree and insert keys as children to specific parents, It is also straightforward to insert children to specific parents due to the fixed nature of the parent child relationship, with a parent having children at indexes ( 2 * Parent index ) + 1, and + 2.). 2.) search (asks user for a character to search in the tree then prints if it is in the tree or not.) 3.) quit (exits program)In C++, answer): Give the inorder, preorder,postorder traversal of the tree below (no spaces in your ART T H E T M A U X H S Y A
- 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)Write a function that inserts the nodes of a binary tree into an ordered linked list. Also write a program to test your function.Assume we have an IntBST class, which implements a binary search tree of integers. The field of the class is a Node variable called root that refers to the root element of the tree. Write a recursive method that prints all of the leaves, and only the leaves, of a binary search tree.
- What is the definition of the public method setRootData for binary tree? Implement it using a recursive helper in a way that the resulting binary tree stayed balanced. C++Write a C++ program to implement binary search tree (BST). Your program should accept a list ofnumbers from the user (minimum 5) and then build a binary search tree from those numbers.Implement following functions: Serach function: Number is found or not leavesCount: Returns number of leaves in binary tree inorder: Print the contents of tree using inorder traversal Note: Define three files: bst.h, bst.cpp, main.cpp to solve this problemWrite a program named ProblemA.cpp that implements the followingfunctions using recursion. Make a menu-based implementation so that you can call each function basedon the user input. • insert: insert a new node in the BSTNode* insert (Node* root, int key); • print: prints the values of all items in the tree, using inorder traversal techniquevoid inorder (Node* root); • search: search a node with a value in the BSTNode* insert (Node* root, int key); • findMinimum: returns the element with the minimum value in the BSTNode* findMinimum (Node* root); • findMaximum: returns the element with the maximum value in the BSTNode* findMaximum (Node* root); • delete: delete a node from the BSTNode* delete (Node* root, int key);
