Implement the following methods in “BST.java” class:  /** Return the height of this binary tree*/   public int height() {   // Left as exercise   return 0; }    /** BreadthFirst traversal from the root  */   public  void breadthFirstTraversal() {   // Left as an exercise   } (Implement inorder traversal without using recursion) Implement the inorder method in BST using a stack instead of recursion. Implement preorder traversal without using recursion) Implement the preorder method in BST using a stack instead of recursion. (Implement postorder traversal without using recursion) Implement the postorder method in BST using a stack instead of recursion.

Java programming question Need help on question: C 8.37:

Project Overview: This project is for testing the use and understanding of stacks. In this assignment, you will be writing a program that reads in a stream of text and tests for mismatched delimiters. First, you will create a stack class that stores, in each node, a character (char), a line number (int) and a character count (int). This can either be based on a dynamic stack or a static stack from the book, modified according to these requirements. I suggest using a stack of structs that have the char, line number and character count as members, but you can do this separately if you wish.Second, your program should start reading in lines of text from the user. This reading in of lines of text (using getline) should only end when it receives the line “DONE”.While the text is being read, you will use this stack to test for matching “blocks”. That is, the text coming in will have the delimiters to bracket information into blocks, the braces {}, parentheses (), and brackets [ ]. A string…

In Java,  Complete the incomplete method of ExpressionTree.java. The incomplete methods are private Node parsePrefix(Scanner input) // Required public void parseInfix(String string) // Optional public void parsePostfix(String string) // Optional Implementations of parseInfix and parsePostfix require use of a stack. Implementation of parsePrefix does not. Read all of the ExpressionTree.java file before starting your implementation, so that you see the helper methods that are provided and get an idea of the context for your implementation.  Although not needed for your implementation, you should be sure you understand how the toStringPrefix, toStringInfix, and toStringPostfix methods work. Note: The main() method accepts a single String as its argument. The String should be a prefix, infix, or postfix mathematical expression with no characters other than operators (+, -, *, and /) and operands (single characters a-z).  As written, the main() method calls parsePrefix() to create an…

Simple JAVA linkedlist code implementation please help and complete any part you can - Without using the java collections interface (ie do not import java.util.List,LinkedList, Stack, Queue...)- Create an implementation of LinkedList interface- For the implementation create a tester to verify the implementation of thatdata structure performs as expected Build Bus Route – Linked List- Your task is to:o Implement the LinkedList interface (fill out the implementation shell)o Put your implementation through its paces by exercising each of themethods in the test harnesso Create a client (a class with a main) ‘BusClient’ which builds a busroute by performing the following operations on your linked list:o§ Create (insert) 4 stations§ List the stations§ Check if a station is in the list (print result)• Check for a station that exists, and onethat doesn’t§ Remove a station§ List the stations§ Add a station before another station§ List the stations§ Add a station after another station§ Print the…

Add Boolean instance variables to indicate whether a node pointer is a thread or regular pointer. You may not add any additional pointers to BSTNode.  The whole idea of threads is that they take advantage of unused BSTNode pointers and thereby reduce the binary tree’s wasted overhead. Add setter/getter methods to access the Boolean instance variables or modify existing setters/getters as necessary.
