8. sum_binary_tree For this function, we are using a data structure called a binary tree, which is useful for storing all different kinds of data. In this problem a binary tree contains a single number, and it has two children, each of which may be either None, or they may be more binary trees. You can see, this is a recursively defined data structure! To recap: each binary tree contains a number and two children. The children are either None or a BinaryTree object. In this function we want to sum up all of the numbers contained in a binary tree and its children (recursively). Sample calls should look like this: >>> sum_binary_tree(BinaryTree(10, None, None)) 10 >>> sum_binary_tree(BinaryTree(10, None, BinaryTree(10, None, BinaryTree(10, None, None)))) 30 >> sum_binary_tree(None)

C++ DATA STRUCTURES Implement the TNode and Tree classes. The TNode class will include a data item name of type string,which will represent a person’s name. Yes, you got it right, we are going to implement a family tree!Please note that this is not a Binary Tree. Write the methods for inserting nodes into the tree,searching for a node in the tree, and performing pre-order and post-order traversals.The insert method should take two strings as input. The second string will be added as a child node tothe parent node represented by the first string. Hint: The TNode class will need to have two TNode pointers in addition to the name data member:TNode *sibling will point to the next sibling of this node, and TNode *child will represent the first child ofthis node. You see two linked lists here??? Yes! You’ll need to use the linked lists
This program allows you to insert some numbers into a binary search tree. Enter the number of nodes will be inserted into a BST: 15 Enter the value of 15 nodes in one line, press enter key when done.

Data Structures;Fun with Trees: The following sequence of numbers will be inserted into a tree data structure: 500, 250, 750, 1000, 2000, 25, 1, 2, 50, 249, 3000, 900, 875, 880, 800, 200, 600 Answer the following questions: 1) What will the binary search tree look like after the numbers are inserted in the given order? 2) From the tree you finished in 1), what will the tree look like each time after the following numbers are deleted (use the delete algorithm discussed in class where the successor is found in the right child subtree): Delete(3000) Delete(50) Delete(750) 3) From the tree you finished in 2), what will the preorder and postorder traversals look like?

C Programming language Binary Search Tree Empirical and Theoretical Results Part 1: we need to define a binary search tree data structure. Also, we need to implement the following functions: 1. Insert Sorted: BSTREE insert(BSTREE root, int num): root points to a node in a binary search tree; num is a number to be inserted in the tree rooted at "root". This function returns the root of the modified tree. 2. Print Elements: void inorder traversal(BSTREE root, FILE *fp): root points to a node in a binary search tree. This function does not return anything, but prints out, to the file specified, the nodes in the tree rooted at "root" by performing an inorder traversal. Part 2: Test the performance of the designed data structure using theoretical and experimental approaches as follows:1. Dataset 1-Dataset is sorted- Add code to insert the numbers 1...n in that order in an initially empty doubly linked list and a binary search tree. a. Run it on different values of n where : i.…
