Question

Write a C++ program that checks whether a binary search tree is an AVL. The input is an arbitrary binary search tree, and the output is binary, so either true or false.

Answer #1

//For checking given tree is AVL or not we need to find left height and right height of each node and difference between left and right height should not be more than 1.

//AVL is balanaced binary serach tree.

//height() is used to find height of given node int height(nod* node) { if(node == NULL) return 0; return 1 + max(height(node->left), height(node->right)); }

//AVL () :Check given BST is AVL or not.

bool AVL(nod *root) { int lh; int rh; if(root == NULL) return 1; lh = height(root->left); // left height rh = height(root->right); // right height if(abs(lh-rh) <= 1 && AVL(root->left) && AVL(root->right)) return true; return false; }

a) Design a recursive linear-time algorithm that tests whether a
binary tree is a binary search tree. Describe your algorithm in
English or with a simple pseudocode program. b) (3 bonus pts.)
Extend the algorithm in a) to test whether a binary tree is an AVL
tree.

In this lab, you will write a program that creates a binary
search tree based on user input. Then, the user will indicate what
order to print the values in. **Please write in C code**
Start with the bst.h and bst.c base code provided to you. You
will need to modify the source and header file to complete this
lab.
bst.h:
#ifndef BST_H
#define BST_H
typedef struct BSTNode
{
int value;
struct BSTNode* left;
struct BSTNode* right;
} BSTNode;
BSTNode*...

Put these integers into a binary search tree and then state the
output of a postorder traversal.
Put EXACTLY ONE SPACE between each integer, so your output looks
like this:
1 2 3 4 5
These are the integers to put into the tree:
41 17 80 25 8 11 50 60 100
Output: ____

This assignment involves using a binary search tree (BST) to
keep track of all words in a text document. It produces a
cross-reference, or a concordance. This is very much like
assignment 4, except that you must use a different data structure.
You may use some of the code you wrote for that assignment, such as
input parsing, for this one.
Remember that in a binary search tree, the value to the left of
the root is less than the...

Write a matlab program that takee a character (a-z) as an input and
checks if that is a vowel or not using switch statment? If the user
inputs any other character, the program should display a proper
error message.

Write code in java
Implement a method to build an AVL tree out of a sorted
(ascending order) array of unique integers, with the
fastest possible big O running time. You may implement private
helper methods as necessary. If your code builds a tree that is
other than an AVL tree, you will not get any credit. If your code
builds an AVL tree, but is not the fastest big O implementation,
you will get at most 12 points. You...

Here is a picture of a Binary Search Tree.
First, construct the Binary Search Tree using the following
BinaryNode as we discussed in class.
public class BinaryNode {
private int value;
private BinaryNode leftChild;
private BinaryNode rightChild;
public BinaryNode(int value) {
this.value = value;
leftChild = null;
rightChild = null;
}
public BinaryNode(int value, BinaryNode leftChild, BinaryNode rightChild)
{
this.value = value;
this.leftChild = leftChild;
this.rightChild = rightChild;
}
public int getValue() {
return value;
}
public void setValue(int value)...

State True or False. i) Binary search is used for searching in a
sorted array. AND ii) The time complexity of binary search is O(log
n). A) True, False B) False, True C) False, False D) True, True

Binary Search Tree with multiple structs?
Hi, I am having an issue with trying to create a binary search
tree while having multiple structs. The struct code provided is
provided for us.
#define CAT_NAME_LEN 25
#define APP_NAME_LEN 50
#define VERSION_LEN 10
#define UNIT_SIZE 3
struct app_info{
char category[CAT_NAME_LEN]; // name of category
char app_name[APP_NAME_LEN]; // name of application
char version[VERSION_LEN]; // version number
float size; // size of application
char units[UNIT_SIZE]; // GB or MB
float price; // price in...
