singly linked list java tutorial

It does not store any pointer or reference to the previous node. Here each node makes up a singly linked list and consists of a value and a reference to the next node (if any) in the list. Add at the End : Add a node at the end of the linked list. There are multiple types of Linked List. Linked List is a linear data structure. Operations: Add at the Start : Add a node the beginning of the linked list. its O(n) since to add a node at the end you need to go till the end of the array. The last node is checked by the condition : p->next = NULL; Here -> is used to access next sub element of node p. NULL denotes no node exists after the current node , i.e. The doubly linked list is a linear data structure in which each node has two links where the first link is used to point the previous node and the next link points to the next node. A simple linked list can be traversed in only one direction from head to the last node. Its O(1). In this article, we will learn about the singly and doubly linked list.
