![]() ![]() This will put the new node in the middle of the two. ![]() Now, the next node at the left should point to the new node. Imagine that we are inserting a node B (NewNode), between A (LeftNode) and C (RightNode). First, create a node using the same structure and find the location where it has to be inserted. Search − Searches an element using the given key.ĭelete − Deletes an element using the given key.Īdding a new node in linked list is a more than one step activity. Insertion − Adds an element at the beginning of the list.ĭeletion − Deletes an element at the beginning of the list. ![]() Simple Linked List − Item navigation is forward only.ĭoubly Linked List − Items can be navigated forward and backward.Ĭircular Linked List − Last item contains link of the first element as next and the first element has a link to the last element as previous.įollowing are the basic operations supported by a list. Last link carries a link as null to mark the end of the list.įollowing are the various types of linked list. Linked List contains a link element called first.Įach link carries a data field(s) and a link field called next.Įach link is linked with its next link using its next link. Linked list can be visualized as a chain of nodes, where every node points to the next node.Īs per the above illustration, following are the important points to be considered. LinkedList − A Linked List contains the connection link to the first link called First. Next − Each link of a linked list contains a link to the next link called Next. Link − Each link of a linked list can store a data called an element. Following are the important terms to understand the concept of Linked List. Linked list is the second most-used data structure after array. Each link contains a connection to another link. Linked List is a sequence of links which contains items. A linked list is a sequence of data structures, which are connected together via links. ![]()
