Data Structures and Algorithms The Complete Masterclass - Linked List Complexities

The video tutorial provides a comprehensive overview of linked lists, focusing on four main operations: access, search, insert, and delete. Each operation is explained in detail, highlighting the complexities involved, such as O(N) for access and search, and O(1) or O(N) for insert and delete depending on the information available. The tutorial also covers different scenarios for insertion and deletion, including at the start, end, and middle of the list. The session concludes with a brief introduction to doubly linked lists, setting the stage for the next lecture.

What are the four complexities associated with linked lists?

Explain how access works in a linked list and its complexity.

Describe the process of searching for an element in a linked list.

What are the three possibilities for inserting an element in a linked list?

What is the time complexity for inserting an element at the start, end, and middle of a linked list?

What is the significance of the head and tail in a linked list?

How do you delete an element from the start of a linked list?

What steps are involved in deleting an element from the end of a linked list?

Explain how to delete an element from the middle of a linked list.

Discuss the differences in time complexity for deletion when you have information about the node versus when you do not.
