in my program i have to seperate a string into seperate characters in a linked list without using inbuilt methods in java.  I have tried to find a way to code this on youtube but there is nothing i can use for the purposes of this assignment. please explain in words how i can do this. i cannot copy any code for this assignment

How would I go about programming this?

Hi, I am not sure what's wrong with my code. Can you please check why it is giving me an error?   In the starter file is a partial implementation of a doubly-linked list in DoublyLinkedList.java. We will write three new methods in this class to provide additional functionality. Write a method addFirst that adds a new element at the beginning of a DoublyLinkedList. Write a method addLast that adds a new element at the end of a DoublyLinkedList. Write a method removeFirst that removes and returns the first element of a DoublyLinkedList. Try to keep your implementations as simple as possible. For example, recall this definition of addFirst in the (Singly) LinkedList class: public void addFirst(E value) { head = new Node(value, head); } In the DoublyLinkedList class, you will need to keep the three instance variables head, tail, and count updated in all methods. Note that addFirst and addLast will be symmetric to each other, as will removeFirst and removeLast (provided in the…

What is the difference in the result of returning the words in a HashSet compared with returning them in an ArrayList?

Consider the list L, which is [11, 121, 1221, 12221, 122221, 1222221,... .] where len (L) ==100. Without writing out the whole of L, write some python code to create L. If tab doesn't work on your browser, you can use spaces to indent. Enter your answer here

hello how are you? can you Please code  this  in Java .. dont use advanced coding and dont edit the whole code and only start editing from where it is menthioned in the code. Please follow the instructions as it is and please see that the input and output are exactly as same as provided in the image. thank you. Write a program that reads a list of integers from input and determines if the list is a palindrome (values are identical from first last to first and last to first). The input begins with an integer indicating the length of the list that follows. Assume that the list will always contain fewer than 20 integers. Output 'yes" if the list is a palindrome and "no' otherwise. The output ends with a newline.

We were given the following code to solve a Pentomino puzzle, several methods might need to be added or editted to solve the problem. The program should take in an input of 3 4 5 6 for 3x20 4x15 5x12 6x10 grids. Then output the number of correct solutions for them (respectively its 2, 368, 1010, and 2339) import java.util.ArrayList;import java.util.LinkedList;import java.util.List; public class DLX {    class DataNode {        DataNode L, R, U, D;        ColumnNode C;                public DataNode() {            L = R = U = D = this;        }         public DataNode(ColumnNode c) {            this();            C = c;        }        DataNode linkDown(DataNode node) {            node.D = this.D;            node.D.U = node;            node.U = this;            this.D = node;            return node;        }        DataNode linkRight(DataNode node) {            node.R = this.R;            node.R.L = node;            node.L = this;            this.R = node;            return node;…

I'm interested in creating a digital personal assistant similar to Alexa and Siri, which can efficiently manage schedules. Specifically, I want to design a tool in Java that allows users to find events during a certain time period. This tool should also enable users to add and cancel events as their schedules change. To achieve this, I plan to use a SkipListMap class with specific operations (get, put, remove, subMap) and a DoublyLinkedList class. Additionally, I'll use the FakeRandomHeight class for debugging and testing. Could you provide guidance on how to approach this project, especially in terms of implementing the SkipListMap class and managing event data efficiently?

I'm trying to understand LargeIntList classes for lists, I was wondering these statements or True or False?  either or, can you please explain your answers? If you need more info, I can provide an image of the textbook I am refering LargeIntList to, it is chapter 6, section 6. Thank you. Supports addition of elements at the front of the list, the end of the list, and anywhere in between. Can hold objects of any Java class. Has only O(1) operations, including its constructor. Provides more than one Iterator.

You will implement some methods in the UndirectedGraph class. The UndirectedGraph class contains two nested classes, Vertex and Node, you should NOT change these classes. The graph will store a list of all the vertices in the graph. Each vertex has a pointer to its adjacent vertices. To get started, import the starter file, Undirected.java into the graphs package you create in a new Java Project. Please do not change any of the method signatures in the class, but you can add any helper methods you deem necessary. Implement the methods described below. You are free to test your code however you prefer. Vertex Class (DO NOT EDIT)The vertex class holds information about the vertices in the graph. It has an int val, a Vertex next that refers to the next vertex in the list of vertices (not necessarily an adjacent vertex), and a Node edge that starts the list of adjacent vertices. Node Class (DO NOT EDIT)This is a simple class to represent an adjacency list of a vertex in the graph.…
