in java Write a method for the Linked Based List class which returns the largest item in the list. If the list is empty return null. Assume that class T is Comparable.DO NOT USE ANY OTHER METHODS OF THE LINKED BASED LIST CLASS. What is the worst case and best case complexity of the code in the previous problem? Explain your answer.
java program : Given the following method to be considered within the SingleLinkedList class, what does this method do? public void Undefined() { Node<E> ptr = head; if (ptr == null || ptr.next == null) return false; E item1 = ptr.data; while (ptr.next != null) ptr = ptr.next; E item2 = ptr.data; if (item1.equals(item2)) { head = head.next; size--; } } If the first element of the list is equal to the second element of the list, then the method deletes the second node. If the first element of the list is equal to the last element of the list, then the method deletes the first node. If the first element of the list is equal to the second element of the list, then the method deletes the first node. If the first element of the list is equal to the last element of the list, then the method deletes the last node.
Write a Java class myLinkedList to simulate a singly linked list using arrays as the underlying structure. Include the following methods: 1. insert an element within the linked list.(this should also work for the front and the rear of the list) 2. Remove an element from the linked list 3. Display (print) the elements of the linked list in order. 4. A method to check if the list is "empty". Test your solution using a linked list that initially has the characters A, B, D, E, F, and G. Insert "C" between B and D. Remove element "F". [Hint: One solution (recommended) is to use 2 arrays. One for the data, and the other for the "next" pointer. Also, consider using dummy nodes for the front, and possibly the rear of the list] Extend the solution so that it simulates a doubly linked list! (hint: You will need a third array to represent the "backward" pointers)
Java - Why is it a bad idea to implement a singly linked list version of a queue with the head of the list as the rear of the queue?
1 Implement a nested class DoubleNode for building doubly-linked lists, where each node contains a reference to the item preceding it and the item following it in the list (null if there is no such item). Then implement static methods for the following tasks: insert at the beginning, insert at the end, remove from the beginning, remove from the end, insert before a given node, insert after a given node, and remove a given node.
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:

in regards to java For this problem, I have a complete linked list program which supports the following commands from the user: insert, display, delete, average, find, insertBefore, insertAfter. insert allows them to insert a number into the current list, display will display the numbers in the current list etc. The program is complete except that I have removed the body of the method for find. Given the following class for the nodes in a linked list: public class Node { ... public Node getNext() {...} // return next field public int getData() {...} // returns data } Assuming that the variable head points to (i.e. contains the address of) the first node of a linked list, write the statements to find the first occurrence of the data value x in the linked list. For example, find(4) would return something like "Found at node position 20" or "Not found" Assume that the nodes in the linked list are counted starting from 1. Your statements will be inserted inside a method like the…
