Q. What is Linked List?
A linked list is a data structure formed by zero or more nodes linked by pointers. Every node has two parts as shown in Figure below. One of them is info field comprising specific information and second field comprising address of next node. First node is pointed by an external pointer known as head. Last node which is known as tail node doesn't comprises address of any node. Thus its next field points to null. Linked list with zero nodes is termed as null linked list.
Figure: Linked List
A huge number of operations can be carried out using the linked list. For a few of the operations such as deletion or insertion of the new data linked list takes constant time however it's time consuming for some other operations such as searching a data.
