Which of the following statements is TRUE about trees? O For an array-based complete binary tree, it takes only constant time to access a node's parent. A binary tree node can never be a root and a leaf at the same time. The three cases of removing a node in a binary search tree are deleting the root, deleting a leaf node, and deleting an internal node (a node that is other than the root and the leaf nodes). O Performing a post-order traversal on an expression tree will not necessarily produce a post-fix expression.

Java Binary Search Trees I have to implement an insert method for a binary search tree. Whats given is here public void insert(E key) throws DuplicateItemException { try { CODE GOES HERE } catch (DuplicateItemException ex) { throw ex; } } I need help with what goes there
There can be only one from the root to any leaf in a Binary Search Tree. There can be only one path from the root to a node in a Binary Tree.
A complete binary tree is stored in an array called treeNodes, which is indexed from 0 to 99. The tree contains 85 elements.
The purpose of this assignment is to practice (JAVA): Implement a binary search tree structure Demonstrate tree traversals Analyze and compare algorithms for efficiency using Big-O notation For this project, you will implement a binary search tree and use it to store a large text file (JAVA). Your program should read text from a file and insert each word in a binary search tree. Do not store duplicate text. Once the tree is populated, print the contents of the tree using an in-order traversal. Next, allow the user to enter words to search for. For each word entered, your program should report the number of elements inspected and whether or not the word was located. Next, allow the user to enter words to remove from the tree. After each removal, print the contents of the tree. Provide an analysis of your remove and search algorithms using Big-O notation. Be sure to provide justification for your claims.

Binary Search Tree. Perform the following operations and instructions. a. Insert the following in BST: 52, 40, 62, 24, 58, 69, 32, 59 b. Identify the following: 1. leaf nodes II. root node iii. height of the tree c. Draw the BST after Deleting node 59 d. Give the following: I. In-order Traversal ii. Pre-order Traversal iii. Post-order Traversal Insert the following in BST: 52, 40, 62, 24, 58, 69, 32, 59
Which statement best represents the action taken when removing an element from a binary search tree that has a single child? A) replacing it with its only child B) comparing the element with the root node C simply deleting it replacing it with a duplicate parent element
In the binary search tree, write a function that takes in a root, p, and checks whether the tree rooted in p is a binary search tree or not. What is the time complexity of your function? def is_bst(self, p: Node):
void F(node<int>&*root){if(root!=0){F(root->left); F(root->right); root->data=0; delete root;}root=0;} this code Select one: a. free the binary tree and returns it empty b. Set all data items in the binary tree to 0 c. remove all items in the binary tree without changing its size d. all of them

An array that represents a Binary Tree is in the following form: binary Tree = To illustrate: [val, arrLeft, arrRight] When arrLeft is the left side of the tree and arrRight is the right side of the tree. const arr1 = [3, [ 8, [ 5, null, null], null], [ 7 // arr1 represents the following Binary Tree: 3 / \ 8 лл 5 N N N /\ N N 7
