Java Design and draw a method called check() to check if characters in a  linked list is a palindrome or not e.g "mom" or "radar" or "racecar. spaces are ignored, we can call the spaces the “separator”. The method should receive the separator as a variable which should be equal to “null” when no separator is used.

Java 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  Second image is ItemNode

In python. Write a LinkedList class that has recursive implementations of the add and remove methods. It should also have recursive implementations of the contains, insert, and reverse methods. The reverse method should not change the data value each node holds - it must rearrange the order of the nodes in the linked list (by changing the next value each node holds). It should have a recursive method named to_plain_list that takes no parameters (unless they have default arguments) and returns a regular Python list that has the same values (from the data attribute of the Node objects), in the same order, as the current state of the linked list. The head data member of the LinkedList class must be private and have a get method defined (named get_head). It should return the first Node in the list (not the value inside it). As in the iterative LinkedList in the exploration, the data members of the Node class don't have to be private. The reason for that is because Node is a trivial class…

Java language Write a method to insert an array of elements at index in a single linked list and then display this list. The method receives this array by parameters

In Java please help with the following:   Sees whether this list is empty.@return True if the list is empty, or false if not. */ public boolean isEmpty(); } // end ListInterface Hint:Node class definition should look something like: public class Node<T> { T element; Node next; Node prev; public Node(T element, Node next, Node prev) { this.element = element;this.next = next;this.prev = prev; } }

The play method in the Player class of the craps game plays an entire game without interaction with the user. Revise the Player class so that its user can make individual rolls of the dice and view the results after each roll. The Player class no longer accumulates a list of rolls, but saves the string representation of each roll after it is made. Add new methods rollDice, getNumberOfRolls, isWinner, and isLoser to the Player class. The last three methods allow the user to obtain the number of rolls and to determine whether there is a winner or a loser. The last two methods are associated with new Boolean instance variables (winner and loser respectively). Two other instance variables track the number of rolls and the string representation of the most recent roll (rollsCount and roll). Another instance variable (atStartup) tracks whether or not the first roll has occurred. At instantiation, the roll, rollsCount, atStartup, winner, and loser variables are set to their appropriate…

Java Programming:  Make AST Nodes: IfNode, WhileNode, RepeatNode. All will have BooleanCompare for a condition and a collection of StatementNode. ForNode will have a Node for from and a node for to. This will have to be of type Node because it could be any expression. For example: for a from 1+1 to c-6  Make parsing functions for each. Java won't let you create methods called if(), etc. parseIf() is an example of a way around that; use whatever you like but use good sense in your names.  Next let's look at function calls. Each function has a name and a collection of parameters. A parameter can be a VAR variable  or something that came from booleanCompare (IntegerNode, VariableReferenceNode, etc). It would be reasonable to make 2 objects - ParameterVariableNode and ParameterExpressionNode. But for this very simple and well-defined case, we can do something simple: ParameterNode has a VariableReferenceNode (for VAR IDENTIFIER) and a Node for the case where the parameter is not a VAR.…

Given the interface of the Linked-List struct Node{     int data;     Node* next = nullptr; }; class LinkedList{ private:     Node* head;     Node* tail; public:     display_at(int pos) const;     ... };   Write a definition for a method display_at. The method takes as a parameter integer that indicates the node's position which data you need to display.  Example: list: 5 -> 8 -> 3 -> 10 display_at(1); // will display 5 display_at(4); // will display 10   void LinkedList::display_at(int pos) const{      // your code will go here  }

Java programming language I have to create a remove method that removes the element at an index (ind) or space in an array and returns it. Thanks!   I have to write the remove method in the code below. i attached the part where i need to write it. public class ourArrayList<T>{ private Node<T> Head = null; private Node<T> Tail = null; private int size = 0; //default constructor public ourArrayList() { Head = Tail = null; size = 0; } public int size() { return size; } public boolean isEmpty() { return (size == 0); } //implement the method add, that adds to the back of the list public void add(T e) { //HW TODO and TEST //create a node and assign e to the data of that node. Node<T> N = new Node<T>();//N.mData is null and N.next is null as well N.setsData(e);   //chain the new node to the list   //check if the list is empty, then deal with the special case if(this.isEmpty()) { //head and tail refer to N this.Head = this.Tail = N; size++; //return we are done.…
