Write a lisp program to check whether a binary tree is a Binary Search Tree. A Binary Search Tree (BST) is a tree in which all the nodes follow the below-mentioned properties: • The left sub-tree of a node has a key less than or equal to its parent node's key. The right sub-tree of a node has a key greater than to its parent node's key. ● 10 14 Example of a binary search tree A list can be used to represent the structure of a binary tree as follow: '(8 (3 (1 () ()) (6 (4 () ())( 7 () ()))) (10 (()) (14 (13) ())))
What are some strategies for optimizing memory usage in a binary search tree data structure?

Write a function in C that returns the second minimum value in a binary search tree at root. struct node { int value; struct node * left; struct node * right; }; int second_min(struct node * root) { return -1; }
Given the following struct that represents a binary tree: struct Node { int key: Node "parent; Node "left; Node "right; Nodelint k) : key(k), parent(nullptr), left(nullptr), right(nullptr) (I: 1: Write a recursive function that prints out the nodes in a tree stored using the above structure in order to cout. The function prints the depth (root depth is at 0) and key of that node separated by a colon (Example "O: 10\n" for root with key 10). Your function CAN NOT create any local variables and can only use what is passed to the function. Use the below function signature (NOTE: this is not a class method). void inorderAndDepth(Node "node, int depth)
Create a binary linked tree, and traverse the tree by using the recursive function. The structure of the tree is as follow: You should input the nodes in pre-order sequence. If a child of a node is NULL, input a space. Write the function of create binary tree, pre-order to print the nodes, in-order to print the nodes and post-order to print the nodes. Count the height of the tree.

C++ language only pls implement a binary tree and multi-child tree that can use a generic data type. and make sure that it can be traverse the tree and can access the children nodes thanks! CODE ONLY ON C++
When iterating over a hierarchical data structure, such as a tree,Group of answer choices 1. Iterating must be done recursively and it must start at the root, visiting each node once. 2. Iterating must start at the children, and must be done with recursion. 3. Iterating starts at the root but can continue depth first or breadth first, and must be done recursively. 4. Iterating must start at the root and it must traverse nodes exactly once.
Please answer in c++ Please implement BST sort and test it for correctness. The program will prompt for the name of an input file and the read and process the data contained in this file. The file contains a sequence of integer values. Read them and construct a binary search tree from the values in the order they are read. Thus; the first number read will be the root of the tree. For this exercise, you may use dynamic data, but it is better to store the numbers sequentially in an array. You do not need to balance the tree as you construct it. When you have read the last value into the BST, conduct an in‐order traversal to output the values in ascending order. Print them 10 to a line in a 5‐character wide field. Note: there may be duplicated value in the input file – in this case each copy of the number should be kept in the tree and output. E.g. if the input was 3 5 3, the output would be 3 3 5. As usual, do not use classes or STL. text file:…
