BST - Binary Search Tree - implement a BSTNode ADT with a data attribute and two pointer attributes, one for the left child and the other for the right child. Implement the usual getters/setters for these attributes -implement a BST as a link-based ADT whose data will be Dollar objects - the data will be inserted based on the actual money value of your Dollar objects as a combination of the whole value and fractional value attributes. - BST, implement the four traversal methods as well as methods for the usual search, insert, delete, print, count, isEmpty, empty operations and any other needed. - BST - Binary Search Tree - implement a BSTNode ADT with a data attribute and two-pointer attributes, one for the left child and the other for the right child.

Assignment 4 The goal of this assignment is to write a Java program that finds the lowest common ancestor of two nodes in a binary tree. To accomplish this goal, you will have to implement a program that allows the user to ask for two letters on the tree shown below, and finds the lowest common ancestor of those two nodes in the tree.

Think about the BiNode basic data structure, which contains references to two other nodes. Both a binary tree (where node1 is the left node and node2 is the right node) and a doubly linked list may be represented by the data structure BiNode (where node1 is the previous node and node2 is the next node). Implement a technique to transform a doubly linked list from a binary search tree (implemented using BiNode). Keep the values in the proper sequence, and carry out the procedure as directed (that is, on the original data structure).
Code those parts only in c++ where it says "code here" 1. Implement the minimum method for binary search trees. 2. Implement the maximum method for binary search trees. 3. Implement the delete method for binary search trees. In the case where the node to be removed has two children, search the right subtree for a replacement value. Do not forget to update the size of the tree when appropriate (including for insertion). 4. Implement the in-order traversal method for binary search trees. 5. Implement the post-order traversal method for binary search trees. Code is here BST.cpp #include<iostream> #include <vector> #include <limits.h> #include "BST.h" using namespace std; BST::BST() { ***********code here********** } BST::~BST() { ***********code here********** } //returns the address of the target node (if found) Node* BST::search(int target) { returnsearch(root,target); } //method to search for target value in BST //If node is not present we will return null Node*…
