Question

Quizplus · Accepted Answer

Doubly-linked list is a variation of linked list in which each node has two pointers, one to the previous node and one to the next node. The circular linked list is another variation in which the last node of the list points to the first node, forming a circular loop. Therefore, both choices A and B are correct variations of a linked list. Triply linked list, on the other hand, is not a commonly used variation and is not as efficient as the other two. Hence, E is not a correct choice.
