Final answer:
In the context of implementing a LinkedSet, a data structure is needed that maintains a collection of non-duplicate elements. Methods such as add, remove, and contains are implemented ensuring the set's integrity. A class for nodes and another for the LinkedSet itself are required for this implementation.
Step-by-step explanation:
When tasked with completing the implementation of a link-based set, such as a LinkedSet, one needs to build upon the data structure principles used in linked lists and apply them to the set abstraction. In a LinkedSet, there are no duplicate elements, and operations such as insertion, deletion, and checking for membership must ensure this property is maintained. To implement a LinkedSet, you might start with defining a Node class that holds a data element and a reference to the next Node. Subsequently, the LinkedSet class itself would maintain a reference to the head node and provide methods that reflect the set operations like add, remove, contains, and size. A critical aspect of these methods is to ensure that when adding an element, it does not already exist in the set, and when removing, only the specific node containing the element is removed without breaking the link between preceding and subsequent nodes.
