linked list linked list is sequence of data structureswhich are connected together via links linked list is sequence of links which contains items each link contains connection to another link linked list is the second most-used data structure after array following are the important terms to understand the concept of linked list link each link of linked list can store data called an element next each link of linked list contains link to the next link called next linkedlist linked list contains the connection link to the first link called first linked list representation linked list can be visualized as chain of nodeswhere every node points to the next node as per the above illustrationfollowing are the important points to be considered linked list contains link element called first each link carries data field(sand link field called next each link is linked with its next link using its next link last link carries link as null to mark the end of the list types of linked list following are the various types of linked list simple linked list item navigation is forward only doubly linked list items can be navigated forward and backward circular linked list last item contains link of the first element as next and the first element has link to the last element as previous basic operations following are the basic operations supported by list insertion adds an element at the beginning of the list deletion deletes an element at the beginning of the list display displays the complete list search searches an element using the given key delete deletes an element using the given key insertion operation adding new node in linked list is more than one step activity we shall learn this with diagrams here firstcreate node using the same structure and find the location where it has to be inserted
