Modify a data structure : Add To Head - part 1

The video tutorial explains how to enhance a linked list by adding functionality to add nodes to the head and tail, remove nodes, and search for data. It focuses on implementing these features by adding methods to the linked list's prototype. The tutorial provides a detailed walkthrough of creating a new node and adding it to the head of the linked list, ensuring proper linkage and updating the head pointer.

What functionalities are planned to be added to the linked list?

• Only removing nodes from the tail

• Searching for data without adding or removing nodes

• Only adding nodes to the head

• Adding nodes to the head and tail, removing nodes, and searching for data

What is the first step in adding a node to the head of a linked list?

• Removing the current head node

• Searching for the node to be added

• Reversing the linked list

• Creating a new node

What parameter is passed to the 'add to head' method to set the value of the new node?

• The current tail node

• A random value

• The previous node

• A value parameter

Why is 'null' passed as the previous parameter when adding a new head node?

• To mark the node for deletion

• Because the new node is the first node

• To indicate the node is temporary

• Because the new node is the last node

What does the 'add to head' method ensure about the head pointer?

• It points to a random node

• It points to the new head node

• It points to the tail node

• It remains unchanged
