Assume ArrayList<E> arrayBinaryTree = new ArrayList<E>( ) is used to store a binary tree. The root node is stored at the cell whose index is 0 (first element in the array). Providing a method with signature public boolean isInternal (int target) to check if the element stored at cell target (refers to an index) is an internal node or not. Return true for yes and false for no.
public boolean isInternal(int target) { int left = 2 * target + 1, right = 2 * target + 2; return target > 0 && target < arrayBinaryTree.size() && ((left < arrayBinaryTree.size() && arrayBinaryTree.get(left) != null) || (right < arrayBinaryTree.size() && arrayBinaryTree.get(right) != null)) && arrayBinaryTree.get(target) != null; }

Preliminaries Download the template class and the driver file. Objective Learn how to traverse a binary search tree in order. Description For the template class BinarySearchTree, fill in the following methods: insert - Inserts values greater than the parent to the right, and values lesser than the parent to the left.parameters elem - The new element to be inserted into the tree. printInOrder - Prints the values stored in the tree in ascending order. Hint: Use a recursive method to...
Please use Java programming: Modify both ArrayList and LinkedList classes and add the following method to both classes: public void reverseThisList(), This method will reverse the lists. When testing the method: print out the original list, call the new method, then print out the list again ------------------------------------------------------------------------- //ARRAY LIST class: public class ArrayList<E> implements List<E> { /** Array of elements in this List. */ private E[] data; /** Number of elements currently in this List. */ private int size; /**...
Please I need help ASAP Java Programing: Binary Search Tree Fully implement the BST class in Listing 25.4 (on page 961 of the 11th Edition of the text). Design and write a (main) driver program to completely test every method in the BST class to ensure the class meets all its requirements. You should read the Listing 25.5: TestBST.java for an idea of what your program should look like. Listing 25.4 BST.java public class BST> extends AbstractTree { protected TreeNode...
Im having trouble implimenting the addAll method.. import java.util.Collection; public interface Tree<E> extends Collection<E> { /** Return true if the element is in the tree */ public boolean search(E e); /** Insert element e into the binary tree * Return true if the element is inserted successfully */ public boolean insert(E e); /** Delete the specified element from the tree * Return true if the element is deleted successfully */ public boolean delete(E e); /** Get the number of...
1) Extend the Binary Search Tree ADT to include a public method leafCount that returns the number of leaf nodes in the tree. 2) Extend the Binary Search Tree ADT to include a public method singleParent-Count that returns the number of nodes in the tree that have only one child. 3) The Binary search tree ADT is extended to include a boolean method similarTrees that receives references to two binary trees and determines whether the shapes of the trees are...
Does not pass the testcase testDTreeAdvancedReRootchangesParent Java I'm trying to extend the implementation of a general tree with new operations that change the structure of the tree. I've created 5 classes: Node.java, SimpleNode.java, Tree.java, RerootableTree.java and SimpleTree.java(which is the main java class that I need to change). The code does not pass ONE TESTCASE : testDTreeAdvancedReRootchangesParent The code passes all the other testcases except theone mentioned above. This is because in the SimpleTree.java the method "reRoot(Node newRoot)" is most likely...
A binary tree is a complete binary tree if all the internal nodes (including the root node) have exactly two child nodes and all the leaf nodes are at level 'h' corresponding to the height of the tree. Consider the code for the binary tree given to you for this question. Add code in the blank space provided for the member function checkCompleteBinaryTree( ) in the BinaryTree class. This member function should check whether the binary tree input by the...
Hello, I've been working on this for a while and I can't figure the rest out.

Feedback X290: Binary Tree Get Difference Exercise Your answer could not be processed because it contains errors: The solution is not recursive Given a binary tree, write a recursive function to return the difference between the sum of all node values at odd levels and sum of all node values at even levels. Define the root node to be at level 1. Here are methods that you can use on the BinNode objects: interface Bin Node { public int value();...
write a new test program called RemoveDuplicates.java. The program reads text input from keyboard or a text file and adds the words to a BST. The program then traverses the BST and prints out the words in order (based on ASCII/UNICODE order) on the screen (or to output text file). Note that you may need to make some changes to BST.java. Sample test: ----jGRASP exec: java -ea removeDuplicates Original Text: a B 2 n w C q K l 0...
