Solution
-
Dynamic variables reside in the heap. So, the correct answer is c) The heap.
-
When you insert an element into a non-empty queue implemented with a linked list, only the rear pointer changes to point to the new element. So, the correct answer is c) Only rear pointer changes.
-
When you insert an element into an empty queue implemented with a linked list, both the front and rear pointers will point to the new element. So, the correct answer is d) Both change.
-
The data structure which allows deletions at both ends of the list but insertion at only one end is an Input-restricted deque. So, the correct answer is a) Input-restricted deque.
-
The code fragment
x.next = x.next.next;removes the node after x from the linked list. The next pointer of x is set to point to the node after the next node, effectively skipping over the next node and thus deleting it.
