Data Structures and Algorithms The Complete Masterclass - Circular Linked List and Implementing a Linked List

The video tutorial covers the basics of circular linked lists, explaining how they differ from singly linked lists by connecting the last node to the first. It then delves into implementing a linked list using object-oriented programming, focusing on creating node and linked list classes. The tutorial demonstrates how to create and connect nodes, and outlines methods for operations like insertion, traversal, and deletion. Finally, it introduces doubly linked lists, highlighting the addition of a previous pointer.

What is the key difference between a circular linked list and a singly linked list?

• Circular linked lists have nodes with two pointers.

• Nodes in a circular linked list are not connected.

• The last node in a circular linked list points to the first node.

• Circular linked lists do not have a head node.

What is the first step in implementing a linked list?

• Creating a node

• Connecting all nodes

• Defining the head

• Inserting data into nodes

Which programming concept is essential for implementing a linked list?

• Event-driven programming

• Procedural programming

• Functional programming

• Object-oriented programming

What is the purpose of the node class in a linked list?

• To perform operations on the list

• To define the structure of each node

• To manage the list's size

• To store the head of the list

What does the linked list class primarily manage?

• Sorting of nodes

• Data storage in nodes

• Node connections and list operations

• Memory allocation for nodes

How do you connect nodes in a linked list?

• By assigning the head to the last node

• By setting the next pointer of one node to another

• By creating a new node for each connection

• By using a loop to iterate through nodes

What is the default value of the 'next' pointer in a newly created node?

• The head node

• The last node

• None

• The previous node

Which method is used to add a new node to a linked list?

• Search

• Insert

• Delete

• Traverse

What is a potential method for finding a node in a linked list?

• Insert

• Delete

• Update

• Search

How is a doubly linked list different from a singly linked list?

• It has nodes with two pointers: next and previous.

• It does not have a head node.

• It only allows traversal in one direction.

• It does not allow node deletion.
