Chapter 19, Problem 12RQE
Program Plan Intro
Binary tree:
- Binary tree is a non-linear data structure.
- Binary tree contains node such as root node that is pointed to two child nodes.
- A root node will have left reference node and right reference node.
- Binary tree will contain more than one self-referenced field.

In Python
Implement a binary search tree and write a function to determine if it is a valid binary search tree.
Create a binary linked tree, and traverse the tree by using the recursive function.
The structure of the tree is as follow:
You should input the nodes in pre-order sequence. If a child of a node is NULL, input a space.
Write the function of create binary tree, pre-order to print the nodes, in-order to print the nodes and post-order to print the nodes.
Count the height of the tree.

- 1. Give a recursive algorithm in pseudocode to compute the diameter of a binary tree. Recall that diameter is defined as the number of nodes on the longest path between any two nodes in the tree. Nodes have left and right references, but nothing else. You must use the height function, defined as follows, in your solution. Your solution will return the diameter of the tree as an integer. function height (Node n) 1. if n = null 2. return -1 3. return 1 + max (height (n.left), height (n.right)) Write your solution below. function diameter (Node n)arrow_forwardConstruct a Binary Search Tree (BST) using the data provided in shaded row and name it “BST-1”. 50 45 65 60 75 90 15 35 70 45 55 40 20 80 95 85 25 50 74 5 Provide answers to the following considering your constructed BST-1: Write a C++ code for the in-order traversal of BST-1.

- 4. Write a recursive algorithm in pseudocode that finds the lowest common ancestor (LCA) of two given nodes in a binary tree T. The lowest common ancestor is defined between two nodes p and q as the lowest node in T that has both p and q as descendants (where we allow a node to be a descendant of itself). If either p or q is null, the LCA is null. For this problem, Nodes have left, right, and parent references as well as a field called level which stores the level of the node in the tree. In the sample tree below, node 5 is on level 0, while nodes 4 and 6 are on level 1. Write your solution here. 5 <- level 0 4 6 < level 1 function lowest_common_ancestor (Node P, Node q)arrow_forwardPLEASE PROVIDE ME THE CODE IN C LANGUAGE.arrow_forwardCreate a function that checks whether a binary tree is balanced.

- Build a Binary Search Tree with the given input order. You must show step by step process of inserting the inputs including both recursive calls and tree diagrams for each step. [ refer to the Insertitem function of Lecture 10 slides to get an idea of doing this.] N.B: Unique Input orders for each student to build the tree are given on a separate file. Write down the input order on your answer script before answering the question. You must use the assigned input order. Do not change the order. TREE INPUT: 4,1,9,3,2,5,6,8,7arrow_forwardb.
