262.(Compare performance) Write a test program that randomly generates 500,000 numbers and inserts them into a BST, reshuffles the 500,000 numbers and per-forms a search, and reshuffles the numbers again before deleting them from the tree. Write another test program that does the same thing for an AVL Tree. Compare the execution times of these two programs.

C++ please Please complete Programming Exercise 4, from pages 1402, from chapter 19 from your textbook. Write a function, singleParent, that returns the number of nodes in abinary tree that have only one child. Add this function to the classbinaryTreeType and create a program to test this function. (Note: Firstcreate a binary search tree.)
Which of the following statements are correct for the expression trees? (Select all that applies.) a. An expression tree is a binary tree. b. The root and internal nodes are operators. c. Each leaf is an operand. d. Subtrees are sub-expressions, with the root being an operator. 2. The height of a binary tree is the maximum number of edges in any root to leaf path. The maximum number of nodes in a binary tree of height h is: a. (2^h)-1 b. (2^(h+1))-1 c. 2*(h+1)-1 3. Which of the following statements are correct? (Select all that applies.) a. The maximum number of internal and external nodes in a proper binary tree with n nodes are (n-1)/2 and (n+1)/2, respectively. b. The maximum number of nodes at level k (k = 0,1,2,...) of a proper binary tree: 2^k c. Depth of a node refers to the number of ancestors. d. Height of a tree refers to the the maximum of the depths of its leaf positions.
48. Fullness Experiment: a. Design and implement a method height for BinarySearchTree that returns the height of the tree (you have already done this if you completed Exercise 32). b. Define the fullness ratio of a binary tree to be the ratio between its minimum height and its height (given the number of nodes in the tree). For example, the tree in Figure 7.5a has a fullness ratio of 1.00 (its minimum height is 3 and its height is 3) and the tree in Figure 7.6c has a fullness ratio of 0.33 (its minimum height is 3 and its height is 9). Implement a method fRatio to be added to the BinarySearchTree class that returns the fullness ratio of the tree. C. Create an application that generates 10 "random" trees, each with 1,000 nodes (random integers between 1 and 3,000). For each tree output its height, optimal height, and fullness ratio. d. Submit a report that includes your code for the height method, the fRatio method, the application code, sample output, and a short discussion. The…
You have a large data set of an area with income and number of people having that income. You want to create an efficient search system using Binary Search Tree (BST) to search an income and related count. Input to be read from in.txt file, Consider a file (you have to create in.txt file and copy the sample data shown below) with total number of people (N) in the first line and next N lines will contain the income and corresponding count separated by space. Output: display the result in console. Do not spend too much time to produce exact output format as we will check the output manually. Tasks: [you have to write a set of functions and test them. Some of them are fairly small] 1. Create a binary search tree based on the income as the key. However, you should also store the corresponding count within the BST node. 2. Print the data in the tree in the inorder traversal to see the keys are in sorted order. Print them like comma separated tuple (income, count). (income, count)..... 3.…
Optional Task: Write a program to implement post-order traversal of a binary tree. hint: For the following binary tree, the program prints nodes using post-order traversal i.e., 4, 5, 2, 3, 1.
Course : Data Structure and Algorithms Write a java/c++ code or an algorithm to solve the following problem. After that dry run and show output of algorithm using an example binary tree. . Write a recursive function to write the parent of the all the nodes while traversing. Like if you traverse the root node write the current node a, parent null. Then if you go to left sub tree, your code will show, current node : b , parent a and so on.
PYTHON PROGRAMMING ONLY (BINARY SEARCH TREE) IF POSSIBLE USE PYCHARM AND INSTALL BINARYTREE IN PYTHON PACKAGES. Create a program that does the following:1. Generate a random binary tree with 12 elements. You can leave the perfect option asFalse.2. Print the tree.3. Test the tree properties. The documentation uses the assert statement.4. Create a binary search tree manually (not using the bst function, but instead buildingit by hand. Put at least 8 elements in it.5. Print this tree.6. Print the values in the tree in several orders (inorder, postorder, preorder, etc.)
Q2. a. What is a Binary Search Tree? b. Draw the Binary Search Tree that results from the insertion, one at a time, of nodes with Keys 27, 59, 21, 38, 54, 63, 8, 70, 15, 12. (Marking Scheme: Each correct insertion in the tree will give you c. Perform the following operations on the original tree and redraw the tree after each operation ) i.deleting 63 ii.deleting 59 iii.Insert 65 iv.Insert 22 d. Write down the inorder, preorder and postorder traversal on the constructed binary tree.

Please Write without plagiarism (write C++ program) Kill Monger Suppose you are playing a killing game and have to kill few of your enemies. You are at a cliff and from there you can see few of them. You see the enemies at your height only. Therefore, you can only kill at the same height. The enemies are forming a balanced binary tree where their General is at the top of the other cliff, his two commanders are on the first level below him. The soldiers are at the lowest level. Total four soldiers are appointed. Under both the commanders exact two soldiers serve. You have to make a strategy to kill the left commander first, than whoever takes his position kill him. Now start killing the right side with same strategy until only one enemy is left at left side. Now increase your height and kill the General. You can only win if only three of your enemies are left. Display the enemies who are left and who have been killed. Don't forget to print your victory message. HINT: Balancing is the…
