one can tell by comparing nodes between two given trees whether they relate to each other, by having a reflected symmetric structure (i.e. being mirror images of each other), having identical structure, or not being related at all. In this assignment, you are asked to implement the following features.
Hard-code some paired lists of integers.
Build binary search trees from each list
Print the binary search trees in the three orders discussed in class.
Determine if the two binary search trees are identical, mirrors of each other, or neither
Remove a number in each tree at random and compare the tree pair again

Further, since the methods of the binary search tree class have been presented with recursive function calls, it is now up to you to implement these recursive functions with iterative loops.

You must write a Class Node, a class TreeChecker and a class BinarySearchTree. For Java users, they must implement the following interfaces respectively:
public interface INode {

   //Getter of node data
   T getData();

   //Setter of node data
   void setData(T data);

    INode getLeftChild() ;

   void setLeftChild(INode leftChild) ;

   INode getRightChild() ;

   void setRightChild(INode rightChild);
  
}
public interface ITree {
   void setRoot(INode root);
INode getRoot();
void preorder();   // print tree in a preorder traversal
void inorder();   // print tree in an inorder traversal
void postorder();   // print tree in a postorder traversal
INode insert(INode root, T data); // insert data into tree
   INode remove(INode root, T data); //search/remove node with data
   T search(INode root, T data); //search and return data if it exists
   INode getMax(INode root); //return node with maximum value of subtree
   INode getMin(INode root); //return node with minimum value of subtree
}  
public interface ITreeChecker {
  
boolean isMirror(ITree root1, ITree root2); // check if two trees are mirror
// images
   boolean isSame(ITree root1, ITree root2); // check if two trees are identical
}

Then if you could run the code in this main class.

public class Main {

   public static void main(String[] args) throws IOException {  
       // build a tree for the following lists
// int array1[] = [4,1,9,12,3,2,8,7,16,20,13,11];
       // int array2[] = [4,1,9,12,3,2,8,7,16,20,13,11];

       //add more examples here

       Bst1 = new BinarySearchTree();
       Bst2 = new BinarySearchTree();
      
      
       //more trees for each example

       treeChecker = new TreeChecker();

       //build each BST

       //print each tree with each order of traversal

       //compare bst1 and bst2 as mirror images with tree checker
       If(treeChecker.isMirror(bst1, bst2))
           Print messages saying the trees are mirrors of each other
       // compare bst1 and bst2 as being identical with tree checker
       Else If(treeChecker.isSame(bst1, bst2))
           Print messages saying the trees are identical to each other
       Else
           Print message saying the trees are not related

       //randomly remove a number from each tree
       //compare bst1 and bst2 again

// more code here to finish regarding comparing the other BST pairs…

Construct this program in C programming Please.

Using a do/while loop, your program will ask/prompt the user to enter in a positive value representing the number of values they wish to have processed by the program or a value to quit/exit. If the user enters in a 0 or negative number the program should exit with a message to the user indicating they chose to exit. If the user has entered in a valid positive number, your program should pass that number to a user defined function. The user defined function will use a for loop to compute an average value. The function will use the number passed to it to determine how many times it will prompt the user to supply a value. The user may enter in any number value positive, floating point or negative. The for loop will continue to prompt the user, calculating the average of the values entered. The function should return the calculated value to the calling function. The calling function using the do/while loop should print out the average and then repeat the process until the user enters in the signal to stop as described previously.

Using C++

Many software applications use comma-separated values to store and transfer data.

In this program, you are asked to implement the movie_call function that will parse a string of the above structure into the corresponding movie name, rating, and movie length.

ex: In "movie name, rating, length", the movie name is "movie name", the rating is "rating", and the length of the movie is "lenght".

This is the code:
#include <iostream>

#include <string>

using namespace std;

/*

Replace the function body with appropriate statements to movie_call

a string of movie details into its corresponding movie name, rating,

and length.

*/

void movie_call (string movie, string& name, string& rating, string& length) {

int comma, comma1;

          comma = movie.find(",");

          name = movie.substr(0, comma);

          movie = movie.substr(comma + 1);

            comma1 = movie.find(",");

            rating = movie.substr(0, comma1);

          length = movie.substr(comma1 + 1);

}

int main() {

string movie_details;

cout << "Please enter information for one movie of your choice: ";

getline(cin, movie_details);

//Add appropriate statement(s) to call the movie_call function

//and display the name, rating, and length

return 0;
