Modify a data structure : Testing Add To Tail and Add To Head

In this video tutorial, the instructor demonstrates how to create a linked list and add nodes to its tail. The process involves initializing a linked list, adding nodes with specific values, and logging the list to verify its structure. The tutorial also covers traversing the list to check node connections and using both 'add to tail' and 'add to head' methods to ensure they work together. The video concludes with a successful demonstration of these methods and introduces the next topic of removing a node from the head.
