Question: 1 / 400

What does the 'AddTail' method do in a linked list?

Removes an item from the list

Finds an item in the list

Adds a value at the end of the list

The 'AddTail' method in a linked list is designed to append a new element at the end of the list. When called, it typically involves creating a new node containing the value to be added, and then adjusting the pointers of the existing nodes to include this new node as the final element.

This functionality is integral to maintaining the list's sequential nature, allowing for easy insertion of elements at the tail without disrupting the existing order. Consequently, the 'AddTail' method ensures that the linked list continues to grow dynamically, reflecting the most up-to-date data.

While it may involve creating a new node as part of its process, the primary purpose of 'AddTail' is explicitly to add a value at the end of the linked list rather than just creating nodes or finding or removing items in the list. This focus on appending elements is what distinctly characterizes the 'AddTail' method.
