Write a class for a bag of strings, where the strings are stored in a binary search
Question:
Write a class for a bag of strings, where the strings are stored in a binary search tree. In creating the binary search tree, you should use the string’s compareTo method, which is described on page 499. The tree itself should use the BTNode class from Figure 9.10.

FIGURE 9.10 Specification and Implementation of the Generic Binary Tree Node Class Generic Class BTNode * public class BTNode from the package edu.colorado.nodes A BTNode provides a node for a binary tree with a reference to an E object as the data in each node. Limitations: Beyond Int. MAX_VALUE elements, treeSize is wrong. Specification Constructor for the BTNode public BTNode(E initialData, BTNode initiallLeft, BTNode initialRight) Initialize a node with specified initial data and links to children. Note that a reference to a child may be null, which indicates that there is no child. Parameters: initialData - the initial data of this new node initialleft and initialRight- references to the children of this new node Postcondition: This new node contains the specified data and links to its children. getData-getLeft-getRight public E getData( ) public BTNode getleft( ) public BTNode getRight( ) These are accessor methods to obtain this node's data or a reference to one of the children. Any of these objects may be null. A null reference to a child indicates that the child does not exist. getLeftmostData public E getleftmostData( ) Accessor method to get the data from the leftmost node of the tree below this node. Returns: The data from the deepest node that can be reached from this node following left links. getRightmostData public E getRightmostData( ) Accessor method to get the data from the rightmost node of the tree below this node. Returns: The data from the deepest node that can be reached from this node following right links.
