a.

Singly linked list

b.

Doubly linked list

c.

Circular linked list

Q20.
A variation of linked list is circular linked list, in which the last node in the list points to first node of the list. One problem with this type of list is?

a.

It waste memory space since the pointer head already points to the first node and thus the list node does not need to point to the first node.

b.

It is not possible to add a node at the end of the list.

c.

It is difficult to traverse the list as the pointer of the last node is now not NULL

d.

All of above

Discuss
Answer: (c).It is difficult to traverse the list as the pointer of the last node is now not NULL
