Implement a class “LinkedList” which has two private data members head: A pointer to the Node class length: length of the linked listImplement the following private method: 1. bool InsertHead(int data); // Use InsertAt FunctionInsert at the start of the linked list. Return true2. bool InsertEnd(int data); // Use InsertAt FunctionInsert at the end of the linked list. Return true3. bool RemoveAt(int index);Remove and delete the node at position “index”. Return true if successful, otherwise, false. this in c++
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
write a program that creates a linked list of points in an x-y coordinate system. Following are the node content of your linked list: head -> P1(0,1) -> P2(1,2) -> P3(10,11) -> P4(0,3) -> P5(17, 16) -> P6(0,0) -> P7(3,4) -> P8(16,1) ->tail Where Pz(x,y) is point z with x and y coordinates in the 2D space. Write a method searchList that recursively searches the linked list of point objects for a specified point w with x1 and y1 cooredinates: Pw(x1, y1). Method searchList should return true if it is found; otherwise, false should be returned. Use your method in a test program that creates the above list. The program should prompt the user for a value to locate in the list. For example: Enter two integer values representing the x and y coordinate of the point you want to look for in the list: 3 4 This point is found Anothet example: Enter two integer values representing the x and y coordinate of the point you want to look for in the list: 0 1 The point does…
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…
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.
Implement a method to remove a node in the middle of a singly linked list (i.e., any node except the first and last node, not necessarily the exact middle), given only access to that node.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
Java: Write a method/programme that will take a generic linked list and make a palindrome of the list. In a seperate test programme the user can add any elements to the generic list and then this list must be made a palindrome. The output should be the original list with the palindrome list added to this list.
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
Build doubly-linked lists using a nested class called DoubleNode, where each node includes a reference to the item before it and the item after it in the list (null if there is no such item). Then put in place static methods for inserting at the start, inserting at the end, removing from the start, removing from the finish, inserting before a given node, inserting after a given node, and removing 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:
Create a simple java program with a linked list that will hold 5 nodes (names of your teacher in the CICS this semester including me, V. Agcaoili). In the program, show how to add nodes by adding a name of faculty from other College as the third element in the linked list. Show also how to access the node(name) V.Agcaoili. Also, show how to change/update nodes by changing the element V.Agcaoili into V.Sinco. Finally, show how to remove nodes by removing the name of the faculty who is not from the CICS Department.
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…
