Implement a method to remove a node from the centre of a singly linked list—that is, any node other than the first and last nodes, not necessarily in that precise order.EXAMPLElnput:the node c from the linked list a->b->c->d->e->fResult: nothing is returned, but the new linked list looks like a ->b->d->e->f
Implement a method to remove a node from the centre of a singly linked list—that is, any node other than the first and end nodes—with access to only that node.EXAMPLEThe node C from the linked list a->b->c->d->e->f should be entered.Nothing is returned as a result, although the new linked list has the shape of an a->b->d->e->f
Write a method max() that takes a reference to the first node in a linked list asargument and returns the value of the maximum key in the list. Assume that all keys arepositive integers, and return 0 if the list is empty
Implement a nested class DoubleNode for building doubly-linked lists, whereeach node contains a reference to the item preceding it and the item following it in thelist (null if there is no such item). Then implement static methods for the followingtasks: insert at the beginning, insert at the end, remove from the beginning, removefrom the end, insert before a given node, insert after a given node, and remove a givennode.
Implement a nested class DoubleNode for creating doubly-linked lists, with each node containing a reference to the item before and following it in the list (empty if no such item exists). Then, for the following jobs, implement static methods: 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.
Write a method which takes as input a singly linked list and print the first duplicatenumber. Please answer it in Java coed.
Write a method find() that takes a linked list and a string key as arguments and returns true if some node in the list has key as its item field, false otherwise.
) Implement a self-organizing list by creating a singly linked list of nodes andundertaking frequent retrievals of data in the list repeatedly and at random. Showhow the list restructures itself when (i) count, (ii) move to front and (iii) transposemethods are used for the same set of frequent retrievals.
Add a method findMiddle() that finds the middle node of a doubly linked list by link hopping, without relying on explicit knowledge of the size of the list. Counting nodes is not the correct way to do this. In the case of an even number of nodes, report the node slightly left of center as the middle. You can assume the list has at least one item. Your findMiddle() code will be located in DoublyLinkedList.java. If you’re using size(), you’re doing it wrong. Starter code for the findMiddle() method: // Janet McGregor 4/20/2053 public E findMiddle() { Node<E> middleNode = header.next; Node<E> currentNode = header.next; // the rest of your code goes here return middleNode.element; } You will test findMiddle() with the following three tests cases. Sample program output: Finding the middle of the list: (1, 2, 3, 4, 5, 6, 7) The middle value is: 4 Finding the middle of this list: (1, 2, 3, 4) The middle value is: 2 Finding the middle of this…
Write a Method Called makePalindrome() that will return a linked list with a palindrome of the calling list. Example [1,2,3] must return [1,2,3,3,2,1] and [8,9,1,4] must return [8,9,1,4,4,1,9,8].
Write a method replace to be included in the class KWLinkedList (for doubly linked list) that accepts two parameters, searchItem and repItem of type E. The method searches for searchItem in the doubly linked list, if found then replace it with repItem and return true. If the searchItem is not found in the doubly linked list, then insert repItem at the end of the linked list and return false. Assume that the list is not empty. You can use ListIterator and its methods to search the searchItem in the list and replace it with repItem if found. Do not call any method of class KWLinkedList to add a new node at the end of the list. Method Heading: public boolean replace(E searchItem, E repItem) Example: searchItem: 15 repItem: 17 List (before method call): 9 10 15 20 4 5 6 List (after method call) : 9 10 17 20 4 5 6
Implement a self-organizing list by building a single linked list of nodes and frequently and randomly retrieving data from the list. Show what happens to the list when the count, move to front, and transpose techniques are applied to the same set of frequently retrieved items.
