QUESTION:
Expression tree is an application of binary tree to represent arithmetic expression.
Write a program to implement an ExpressionTree class that can represent an arithmetic expression with binary operators and integer operands including floating-point. Limit the operators to addition, subtraction, multiplication and division. Operands can be constants or variables. Your class should be able to build a tree from its signature, and evaluate it on a set of values for the variable operands.
Add to the BinarySearchTree class a member function string smallest() const that returns the smallest element of the tree. Provide a test program to test your function.
#include <iostream>#include <string>using namespace std;class TreeNode{public:void insert_node(TreeNode* new_node);void print_nodes() const;bool find(string value) const;private:string data;TreeNode* left;TreeNode* right;friend class BinarySearchTree;};class BinarySearchTree{public:BinarySearchTree();void insert(string data);void erase(string data);int count(string data) const;void print() const;private:TreeNode* root;};BinarySearchTree::BinarySearchTree(){root = NULL;}void BinarySearchTree::print() const{if (root != NULL)root->print_nodes();}void BinarySearchTree::insert(string data){TreeNode* new_node = new TreeNode;new_node->data = data;new_node->left = NULL;new_node->right = NULL;if (root == NULL) root = new_node;else root->insert_node(new_node);}void TreeNode::insert_node(TreeNode*…

You must use the textbook's BinarySearchTree ADT as the base for your code. (See attached file.) Of course, you will need to modify the code a bit. Build a function that searches for a given item in the BST in the tree. It must return the number of compares that it used before returning as well as an indicator telling whether the sought item was or was not in the tree. Build a driver than inserts 10K unique random ints into the BST. Then, use the search function to seek the 1st, 500th, 5,000th, and 10,000th integers that were inserted in the tree, reporting the number of compares for each item. Also seek at least 2 integers that are not in the tree, one integer must be larger than the largest value in the tree and one integer must be within the range of values that are stored within the tree. Report the number of compares for these searches as well.arrow_forward
