The linked list is one of the most important concepts in data structures and data structures to learn while preparing for interviews. Having a good grasp of Linked Lists can be a huge plus point in a coding interview.<\/p>\n

What is a Linked List?<\/h2>\n

A linked list is a linear Data Structure, consisting of a group of nodes stored at random addresses. In a linked list the elements are linked using pointers.
\nEvery node stores the data and address of the next node. Every node consists of 2 parts:<\/p>\n

Data<\/strong>: The Data which is stored at a particular address.
\nReference<\/strong>: The address of the next node of the linked list.<\/p>\n

Linked List Representation<\/h3>\n

Linked list can be represented as the connection of nodes in which each node points to the next node of the list. Below is the representation of the linked list <\/p>\n

Till now, we have discussed the array data structure to organize the group of elements that are to be stored individually in the memory. However, Array has several advantages and disadvantages that must be known to decide the data structure that will be used throughout the program.<\/p>\n

Types of Linked Lists<\/h2>\n

There are three common types of linked list .<\/p>\n

    \n
  • Singly Linked List<\/li>\n
  • Doubly Linked List<\/li>\n
  • Circular Linked List<\/li>\n<\/ul>\n

    Singly Linked List<\/h3>\n

    A singly list is a linked list that is unidirectional, i.e. it can be traversed in only one direction starting from the head of the linked list to the end node (tail). In a Singly Linked List, every node contains:
    \nA data<\/strong> field.
    \nAn address<\/strong> field points to the next node.<\/p>\n
