Write a Java method that prints 1st, 3rd, 5th, etc. nodes in the double linked list. b) Write a java method to display the double linked list in the reverse 2-Quick Sort is one of the fastest sorting algorithms in Computer Science. a) Write the quick sort algorithm.
Types of Linked List
A sequence of data elements connected through links is called a linked list (LL). The elements of a linked list are nodes containing data and a reference to the next node in the list. In a linked list, the elements are stored in a non-contiguous manner and the linear order in maintained by means of a pointer associated with each node in the list which is used to point to the subsequent node in the list.
Linked List
When a set of items is organized sequentially, it is termed as list. Linked list is a list whose order is given by links from one item to the next. It contains a link to the structure containing the next item so we can say that it is a completely different way to represent a list. In linked list, each structure of the list is known as node and it consists of two fields (one for containing the item and other one is for containing the next item address).
1- consider the following implementation of double linked list class.
public class DLIST<E> {
static class Node<E>{
private E data, Node<E> next, Node<E> prev;
private Node(E dataItem, Node<E> nextnode, Node<E> prevnode){ // constructor
data = dataItem;
next = nextnode;
prev = prevnode
}
private Node(E dataItem) { //constructor
data = dataItem;
next = null; prev=null;
}
}
private Node<E> head=null;
private Node<E> tail=null; //initialisation
}
a) Write a Java method that prints 1st, 3rd, 5th, etc. nodes in the double linked list.
b) Write a java method to display the double linked list in the reverse
2-Quick Sort is one of the fastest sorting algorithms in Computer Science.

b) Sort the following array using the QuickSort algorithm (Assume the first element as the pivotal element).
