Modify a data structure : Add To Head - part 2

The video tutorial explains how to add a new node to the head of a linked list. It covers two scenarios: when the list is empty and when it already contains nodes. For an empty list, the new node becomes both the head and tail. For a non-empty list, the new node is connected to the existing nodes by adjusting pointers. The tutorial also details the implementation of the add to head method, ensuring the new node is correctly set as the head in both scenarios.
