Singly linked lists

Singly Linked Lists Definition: A linked list is a colleciton of nodes that together form a linear ordering. node : A compound object that stores a reference to an element and a reference, called next , to another node. Reference to another node Reference to an element next Element Node head next element next next next element element element Baltimore Rome Seattle Toronto link: The next reference inside a node is a link or pointer to another node. We can start from a given node, and move from it to the next and so on. This is called link hopping or pointer hopping . head next element next next next element element element Baltimore Rome Seattle Toronto head: The first node of a linked list tail: The last node of a linked list - it has a null next reference. head next element next next next element element element Baltimore Rome Seattle Toronto Such a linked list is called a singly linked list. tail pointer to a next node pointer to an element node Illustration of a linked list in memory: pointer to a next node pointer to an element node pointer to a next node pointer to an element node pointer to a next node pointer to an element node [...]... next element element Seattle next Toronto next element Baltimore should be removed How to insert a new node in the middle of a singly linked list? How to remove a node which in the middle of a singly linked list? Data Structure Exercises 5.1 Write a Java program to create a linked list as shown below head tail Φ …… 0 1 9 ... head = null; Node tail = null; Public Head_and_Tail linked_ list () { Node x = null; for (int i = 0; i < 10; i++) {x = new Node(); x.setElement(new Integer(i)); if (i == 0 ) {x.setNext(null); tail = x;} else x.setNext(head); head = x; } return new Head_and_Tail(head, tail);} } Deleting an Element at the Tail Deletion of an element at the tail of a singly linked list takes more effort The difficulty is related.. .Singly Linked Lists and Arrays Class Node Here is an implementation of nodes in Java: public class Node { private Object element; private Node next; public Node() { this( null, null ); } public Node( Object e, .
