Instructions. c++ binary search trees. 1. Implement a function that will build a binary search tree. 2. Using the function above create a binary search tree. 3. Implement a swapSubtrees() function that will take a pointer to a root node and a target value. Function will search for the target value in the tree and swap all left nodes with right nodes for all descendant nodes. 4. Pass the tree created in step 2 to test swapSubtrees() function. 5. You can use the inorder, postorder or preorder traversal implemented in class to display and confirm the logic. (trace it by hand as well) TreeNode{ int val; TreeNode* left = nullptr; TreeNode* right = nullptr; TreeNode(){} TreeNode(int val): val(val){} };
Write a C++ program to create a binary search tree with the following operations: 1) Create Binary Search Tree. 2) Postorder Traverse. 3) Inorder Traverse. 4) Preorder Traverse 4) Delete Node.
Create a Binary Search Tree Class with the following four Operations using a single C++ program: Operations: 1. Insert(int n) : Add a node the tree with value n. Its O(lgn) 2. Find(int n) : Find a node the tree with value n. Its O(lgn) 3. Delete (int n) : Delete a node the tree with value n. Its O(lgn) 4. Display(): Prints the entire tree in increasing order. O(n).
COMPLETE THE GIVEN CODE BELOW TO SOLVE THE PROBLEM - PYTHONIn this problem, you are going to implement a filesystem using a tree data structure. Similar to a filesystem, each node (or file), may have multiple children. If the specified path does not exist, then you should disregard that file. Once you are done adding elements to the filesystem, you should print the directory structure in the specified format. Required modifications: 1. Insertion of a new element 2. Printing of the directory from the root node. 3. Parsing of the input. Input Format First line is the name of the root directory. Second line, n, is the number of subdirectories that follows. For each line that follows, it shows the following format: Filename-root node,next path,next path,... Constraints You may assume that the filenames are all alphabetical characters with no special characters. n < 100 The maximum path length is 20 (including the root directory). You may assume that there are no similar…
1. Create a Java program that prompts the user the initial choices for the Binary Search Treea. User chooses 1: Insert, User chooses 2: Delete, User chooses 3: Show Binary Tree, User chooses 4: Exit Program 2. Insertion in a tree should be such that it obeys the main properties of the binary search tree. The basic algorithm should be: a. If the node to be inserted is greater than the existing root, move down a level through the right pointer of the root. b. If the node to be inserted is lesser than the existing root, move down a level through the left pointer of the root. c. Repeat this process for all nodes till the leaves are reached. d. Insert the node as the left or right pointer for the leaf (based on its value - if it is smaller than the leaf, it should be inserted as the left pointer; if it is larger than the leaf, it should be inserted as the right pointer) 3. Deletion is a bit more complicated than insertion because it varies depending on the node that needs to be deleted…

Q: Construct a Huffman Tree for the following data and assign code to each character. What is the size of file after coding, if file contains only given data? a(45), b(13), c(12), f(5), d(16), e(9)
in c++ Draw the tree after the insertion of keys 33, 31, 60,90,86,81,96,87,94, 21, 11 and 18, in this order. Consider the above values and perform The Following: 1) Write code for Insertion of above values in trees. 2) perform Breadth First Search AND Depth First Search and display results. 3) Perform Preorder, in order, and post order traversal and show the outputs. 4) Write a code to delete 87 and 21, and 90 from above tree.
CODE needs to be written in c++ 1.- Construct the below tree using the below node class 2.- Save the tree on a txt file using recursive function that takes an ofstream and a node pointer. Write the file using a pre-order traversal, following the below format (where leaves are denoted by #A, and nodes #Q ) #Q Is it a mammal? #Q Does it have stripes? #A Is it a zebra? #A Is it a lion? #Q Is it a bird? #Q Does it fly? #A Is it an eagle? #A Is it a penguin? #A Is it a gila monster? class node { public: string data; node* left; node* right; };
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.)
Create a Binary Search Tree Class using C++ with the following Operations: Operations: Insert(int n) : Add a node the tree with value n. Its O(lgn) Find(int n) : Find a node the tree with value n. Its O(lgn) Delete (int n) : Delete a node the tree with value n. Its O(lgn) Display(): Prints the entire tree in increasing order. O(n).
Write 5 functions in C++ for a binary search tree. DeleteAll() deletes all the nodes in the binary tree recurively. findNode(int item) //finds the node in the tree ITERATIVELY. countNonLeaves() takes a binary tree and counts the number of nodes that are not leaves in the given Binary Tree. OneChild() Calculate the number of nodes that have only one child in a given Binary Tree. findRange() return the range value of a Binary Search Tree. [ max(BST), min(BST) ] where max is the maximum value of the BST and min is theminimum value of the given BST. All of these functions should be called in the main and tested. Thank you.
