A Variation of a Linked List Is a Circular Linked

question 49

Multiple Choice

A variation of a linked list is a circular linked list where the last Node in the list has next = head rather than next = null. One problem with this type of list is that

• A) it wastes memory space since head already points at the first Node, so the last one does not need to
• B) there is no ability to add a new Node at the end of the list since the last Node points at the first Node
• C) it is more difficult to traverse the list since the old terminating condition, (next = = null), is no longer True for the last node
• D) a header Node for this type of list is more complex
• E) all of the above
