> Printing BST in descending order can be done
using reverse inorder traversal of BST.
Let us take an example to understand the solution.
This is a Binary Search Tree and following will be the inorder and reverse inorder of above binary search tree
As you can observe that Reverse Inorder of BST gives us nodes in descending order.
Code:
public void reverseSorted(Treenode root){ //Check if root is null or not, if null then return if(root == null) return; //recursively call Right node first reverseSorted(root.right); //Print data of the root node System.out.print(root.val+" "); //At last, recursively call the Left node reverseSorted(root.left); }

Binary Search Tree Part A: The code attached in this document is a sample code to demonstrate insert operation in binary search tree. Please fill in the missing part for the insert method to make the program work. The expected output should be as follows. 20 30 40 50 60 70 80 Part B: Find Lowest Common Ancestor (LCA) of a Binary Search Tree. According to WikiPedia definition , The lowest common ancestor is defined between two nodes v and...
In Java: Given the following binary tree class, write a recursive method called size() which will find the number of nodes in the subtree rooted at the current node: class myBinaryTree{ int myValue; myBinaryTree left; myBinaryTree right; myBinaryTree(int inValue) {myValue = inValue;} public int size(){ <CODE WRITTEN HERE> } }
Consider a binary search tree of positive integers without duplicates. Implement (write out) a program to find the second greatest element in the tree. The Second function is a member function of class BinarySearchTree. The function returns zero if the tree is empty or has only one element, otherwise it returns the value of the second greatest element. Based on the classes provided below, write the implementation of Second in the solution box, including any helper functions (if any) that...
IN JAVA 2 A Binary Search Tree The goal of this lab is to gain familiarity with simple binary search trees. 1. Begin this lab by implementing a simple class that represents a "node” in a binary search tree, as follows. public class MyTreeNode<t extends Comparable<T>> { public T data; public MyTreeNode<T> leftchild; public MyTreeNode<T> rightChild; public MyTreeNode<T> parent; 2. Have the second member of your pair type in the code for the simple binary search tree interface. public interface...
C++ (Using Binary Search Trees) other methods will result in downvote Implement the binary search tree methods (bst.cpp) for the binary search tree provided in the header file. Test your implementation with the included test. bst.h bst_test.cpp Note: Your implementation must correspond to declarations in the header file, and pass the test. Do not modify these two. I will compile your code against these. If the compilation fails, you will get down vote. bst.h #ifndef BINARY_SEARCH_TREE_H #define BINARY_SEARCH_TREE_H #include <string>...
