Question
In a doubly linked list, how many pointers does each node have?
- a. One
- b. Four
- c. Three
- d. Two
Solution
In a doubly linked list, each node contains two pointers. One pointer references the next node in the sequence, while the other pointer refers to the previous node. This structure allows for traversal of the list in both forward and backward directions.
Explanation:
- Node Structure: Each node is composed of three primary components: data, a pointer to the next node (often termed "next"), and a pointer to the previous node (termed "prev").
- Traversal Direction: The presence of both of these pointers is what differentiates a doubly linked list from a singly linked list, which only has a pointer to the next node. This dual-pointer system allows for more versatile data manipulation and retrieval.
Final Answer
d. Two
