Consider a singly linked list data structure as show below, implement the most efficient algorithm to detect whether the elements in the list form a palindrome or not, the method must return true/false accordingly.   class SinglyList:     class _Node:         def __init__(self, e, next):             self._element = e             self._next = next     def __init__(self):         self._head = self._tail = None    def is_palindrome(self)->bool:

An approach to remove nodes from a linked list that have the same key is provided.

The tail of a linked list is distinguished from other nodes because its next pointer is:A. void B. empty C. NULL D. None of the above.

Lab 19 Building a linked list Start this lab with the code listed below. The LinkedList class defines the rudiments of the code needed to build a linked list of Node objects. You will first complete the code for its addFirst method. This method is passed an object that is to be added to the beginning of the list. Write code that links the passed object to the list by completing the following tasks in order: 1. Create a new Node object. 2. Make the data variable in the new Node object reference the object that was passed to addELKEt, 3. Make the next variable in the new Node object reference the object that is currently referenced in variable first. 4, Make variable first reference the new Node. Test your code by running the main method in the LinkedLiatBunner class below. Explain, step by step, why each of the above operations is necessary. Why are the string objects in the reverse order from the way they were added? public class LinkedList private Node first; public LinkedList () {…
