(Test perfect binary tree) A perfect binary tree is a complete binary tree with all levels fully filled. Define a new class named BSTWithTestPerfect that extends BST with the following methods: (Hint: The number of nodes in a perfect binary tree is 2^(height+1) - 1.) /** Returns true if the tree is a perfect binary tree */ public boolean is PerfectBST() Use https://liveexample.pearsoncmg.com/test/Exercise25_03.txt to test your code.

Please fill in the code gaps if possible. This problem has been giving me trouble. Any help is appreciated. public class Node { private String element; // we assume elements are character strings private Node next; /* Creates a node with the given element and next node. */ public Node(String s, Node n) { //fill in body } /* Returns the element of this node. */ public String getElement() { //fill in body } /* Returns the next node of this node. */ public Node getNext() { //fill in body } // Modifier methods: /* Sets the element of this node. */ public void setElement(String newElem) { //fill in body } /* Sets the next node of this node. */ public void setNext(Node newNext) { //fill in body } }
24. Add the following new method in the BST class. /** Returns the number of nodes in this binary tree */ public int getNumberofNodes () Requirements: a. Don't use return size; b.write a recursive method that returns the number of nodes starting from www the root.
class IntBTNode { private int data; private IntBTNode left; private IntBTNode right; } Write a new static method of the IntBTNode class to meet the following specification. Make the method as efficient as possible (do not visit nodes unnecessarily). public static int max(BTNode root) // Precondition: root is the root reference of a nonempty binary SEARCH // tree. // Postcondition: The return value is the largest value in the tree.

Assume we have an IntBST class, which implements a binary search tree of integers. The field of the class is a Node variable called root that refers to the root element of the tree. 1) Write a recursive method for this class that computes and returns the sum of all integers less than the root element. Assume the tree is not empty and there is at least one element less than the root. 2) Write a recursive method that prints all of the leaves, and only the leaves, of a binary search tree. 3) Write a method, using recursion or a loop, that returns the smallest element in the tree.
