Assignment 4 (Maximum marks: 20)-BINARY SEARCH TREE-INSERT DATA FROM FILE CIS 265- Spring 2018 Due Date: April 15, 2018 (Sunday) This assignment will help you get familiar with Binary Search Trees and the concepts of traversing the tree using techniques of Inorder, Preorder and Postorder, and searching, adding and removing nodes. The class lecture slides will also help you complete the assignment. Problem Description: city.txt has a list of cities which are added using Binary search tree insert algorithm. . Cities are to be traversed in Inorder, Preorder and Postorder from the root WITHOUT USING RECURSION. You need to use Stack push() and pop() to accomplish your task Then you need to search whether a city exists in the tree or not. If the city exist, its path fronm the root is displayed for you, else display false. 1) Write the code for the following methods to implement traversal BST in BST.java: protected void inorder[TreeNodecE> root) protected void postorder(TreeNodecE> root) protected void preorder(TreeNodecE> root) public boolean search(E e) 2) Run the program for city.txt already provided and see if the traversal output is displayed correctly. Below is the file in which students will have to write their code wherever they find a comment: YOUR CODE HERE BST.java package bst; import java.util.Stack; public class BSTKE extends ComparableE implements TreecE protected TreeNodecE> root; protected int size e; * Create a default binary tree public BSTO Create a binary tree from an array of objects public BST(E[] objects) for (int i . 0; ?
