A linked list can be designed so that the nodes consist of just two reference variables. One refers to the element, while the other node is a self-reference for linked list purposes. What is the benefit of this design for a linked list?
What will be an ideal response?
In this design, all of the information related to the object that is being managed in the linked list is captured in
the element. The object does not have to have a reference to another object as an instance variable, and the object does not
have to know that it is part of a linked structure. This supports the separation of the implementation of the linked list from the
contents of the linked list.
