Operations of Linked List

A linked lists are one of the most widely used and effective data structures, with applications in every programming language, including C, C++, Python, Java, and C#.

Question

2) Suppose you have a linked list class that provides the following
methods:
// constructor.
// returns size of the list.
LinkList ()
int size ();
void insertHead (Object data) // insert new data at the head of
// the list.
// remove and return the Object at
// the head of the list.
Object removeHead ()
void insertTail (Object data) // insert new data at the tail of
// the list.
The class below is an implementation of a stack using the linked
list class. Fill in the method implementations:
class Stack
{
private Stack s;
public Stack ()
{
public void push (Object x)
{
}
public Object pop () // assume stack is not empty
{
}
public boolean isEmpty()
{
}

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 }

Please fill in all the code gaps if possible: (java) public class LinkedList { privateLinkedListNode head; **Creates a new instance of LinkedList** public LinkedList () { } public LinkedListNode getHead() public void setHead (LinkedListNode head) **Add item at the front of the linked list** public void insertFront (Object item) **Remove item at the front of linked list and return the object variable** public Object removeFront() }
Which best describes this axiom: aList.getLength ( ) = ( aList.remove ( i ) ) . getLength ( ) + 1 You cannot remove an item from from existing list that is empty Removing an item from an existing list decreases its length by one Removing an item from an existing list increases the list size by one None of these
