//Method to insert node at front of doubly linked list

public void addFront(int x)
{
DListNode newnode=new DListNode();//create newnode

newnode.key=x;
newnode.previous=null;
newnode.next=head;
head=newnode;//new node becomes head node
  
if(head==NULL)
tail=newnode;
  
}

    Given a singly-linked list interface and linked list node class, implement the singly-linked list which has the following methods in Java: 1. Implement 3 add() methods. One will add to the front (must be O(1)), one will add to the back (must be O(1)), and one will add anywhere in the list according to given index (must be O(1) for index 0 and O(n) for all other indices). They are: void addAtIndex(int index, T data), void addToFront(T data), void addToBack(T...

    In java Write a method public void printReverse() that prints the elements of a doubly linked list in reverse. Write a method public void delete5FromTheEnd() which deletes the 5th element from end of the list. Note that if you reach the end then you have to reverse the direction of counting. In the main() method of the test class, create a randomly generated Doubly-Linked list of 10 Integers. Next, call the delete5FromTheEnd() method and print the lists iteratively until the...

    C++ Create a class that implements a sorted, doubly-linked list: Start with a copy of the sortedList class. Call your new class doublyLinkedList. Convert the baseline code into a doubly linkedlist, and thoroughly test all existing operations (make sure to check all edge conditions), and then implement the new operations below. The class should have the following additional class methods: • A reverse method: this method will reverse the order of the doubly linked list. This method takes no parameters,...

    Linked Lists: Suppose you have a doubly linked list with both head and tail pointers, that stores integers. Implement a non-recursive function that takes a linked list, searches for an integer, and removes the node with the first occurrence of that integer and also removes the node directly after it regardless of value . This function will return to address of the resulting list. You ca n assume that there will be at least three nodes, and if there is...
