![Blurred answer](/static/compass_v2/solution-images/blurred-answer.jpg)
- JAVA please Given main() in the ShoppingList class, define an insertAtEnd() method in the ItemNode class that adds an element to the end of a linked list. DO NOT print the dummy head node. Ex. if the input is: 4 Kale Lettuce Carrots Peanuts where 4 is the number of items to be inserted; Kale, Lettuce, Carrots, Peanuts are the names of the items to be added at the end of the list. The output is: Kale Lettuce Carrots Peanuts Code provided in the assignment ItemNode.java:I am having trouble determining time complexity when it comes to finding the runtime of a method or function. I need to know what the runtime for the following methods are. Any further explanation would also be helpful. All of these methods are dealing with a binary search tree in java. 1. public String getAllValues() - return a String that contains the elementsof the tree in ascending order. All elements are separated by a space. 2. public int numberNodes() - return the total number of nodes in the tree. 3. public void insertList(int[] list) - insert all of the values from list intothe tree. Note: My Method just goes through an array calling working insert() method on all the values in the list[] array. 4. public int removeLessThan(int value) - this method removes all integers strictly less than value from the tree. It also returns the number of nodes itremoved. Note: In this method I first call a method to count nodes less than I call another method to recursively remove by…Sorting Create a MyLinkedList class with inner Node class, data fields, and the insert(element) method. Implement a toString method to return all nodes in MyLinkedList. Implement a recursive sorting and a non-recursive sorting method.
- Implement LeafNode and InteriorNode classes for the expression tree as discussed on this page Use this template: Please don't change any function namesAdd any methods if necesssaryTODO: Remove the pass statements and implement the methods. '''class LeafNode:def __init__(self, data):self.data = datadef postfix(self):return str(self)def __str__(self):return str(self.data)def prefix(self):passdef infix(self):passdef value(self):return self.dataclass InteriorNode:def __init__(self, op, left_op, right_op):self.op = opself.left_op = left_opself.right_op = right_opdef postfix(self):return self.left_op.postfix() + " " + self.right_op.postfix() + " " + self.opdef prefix(self):passdef infix(self):passdef value(self):passif __name__ == "__main__":# TODO: (Optional) your test code here.a = LeafNode(4)b = InteriorNode('+', LeafNode(2), LeafNode(3))c = InteriorNode('*', a, b)c = InteriorNode('-', c, b)To finish up the definition of the Node class, we need at least two constructor methods. We definitely want a default constructor that creates an emptyNode, with both the Element and Link members set to null. We also need aparameterized constructor that assigns data to the Element member and setsthe Link member to null.Write the code for the Node class:When a Java object is instantiated using a tree from the standard library to store sorted data, what kind of tree is returned?
- Can you help me with a C++ programming task I am trying to complete for myself please: Write a program (in main.cpp) that: Prompts the user for a filename containing node data. Outputs the minimal spanning tree for a given graph. You will need to implement the createSpanningGraph method in minimalSpanTreeType.h to create the graph and the weight matrix. There are a few tabs: main.cpp, graphType.h, linkedList.h, linkedQueue.h, queueADT.h, minimalSpanTreeType.h, and then two data files labeled: CH20_Ex21Data.txt, CH20Ex4Data.txtIn Java, Explain when it might be preferable to use a map instead of a set.Write a recursive method body for the static method shown below. Reports the number of text nodes with the same value as val in * the tree. * Gensures * countValText = [the number of nodes in t that are not a tag and have the same value as val] private stațic int çountValȚext(XMLȚree t, String val) (
- 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…We have discussed binary search trees, where the nodes in a tree are stored such that an inorder traversal of the tree will produce a list of the data in ascending order. In this lab, you must create a descending order version of the BST, where the largest value is stored as the leftmost node, and the smallest value is stored as the rightmost node. Complete the binary search tree class, named BST and stored in the file named BST.java. The following methods are required for your code to work with the grading tests. a constructor to create an empty tree (This is provided in the template.) public void insert(int key) : the key should be inserted (in a new Node) in the tree, such that the tree is in descending order. public void delete(int key) : the given key should be removed from the tree. public String inorderTraversal() : Perform an inorder traversal of the tree, constructing a String that contains the items in the tree, in the order visited, with a space between each item. Note 1:…In Java I'm trying to make a Red Black Tree through inheritance with the Binary Tree I created (as provided along with the Binary Node) yet I'm having a lot of difficulty knowing where and how to start as well as how to override and even create the Insert and Remove functions for the Red Black Tree. Code and assistance in this topic will be greatly appreciated... here is the code I'm utilizing for this project. Binary Node I created: public class BinNode{private String data;private BinNode left;private BinNode right;private int height; //height fieldpublic BinNode(){data = "";left = null;right = null;}public int getHeight() {return height;}public void setHeight(int height) {this.height = height;}public BinNode(String d){data = d;left = null;right = null;}public void setData(String d){this.data = d;}public String getData(){return this.data;}public void setLeft(BinNode l){this.left = l;}public BinNode getLeft(){return this.left;}public void setRight(BinNode r){this.right = r;}public…
