About this MCQ
This Medium Data Structures MCQ checks one syllabus fact.
The question is: “What does Doubly linked list refer to?”
The accepted answer is B. A linked list where each node has pointers to both the next and previous nodes.. A linked list where each node has pointers to both the next and previous nodes is the fact required by What does Doubly linked list refer to option B Option A A data structure that maps keys to values using a hash function for fast lookup does not match the stem it is a near-miss used to catch incomplete recall of A linked list where each node has pointers to both the next and previous nodes Option C A self-balancing binary search tree where the height difference between subtrees is at most one does not match the stem it is a near-miss used to catch incomplete recall of A linked list where each node has pointers to both the next.
- A. A data structure that maps keys to values using a hash function for fast lookup.
Why not A: “A data structure that maps keys to values using a hash function for fast lookup.” is not correct. The accepted answer is B. A linked list where each node has pointers to both the next and previous nodes.. A linked list where each node has pointers to both the next and previous nodes is the fact required by What does Doubly linked list refer to option B Option A A data structure that
- B. A linked list where each node has pointers to both the next and previous nodes. ✓
- C. A self-balancing binary search tree where the height difference between subtrees is at most one.
Why not C: “A self-balancing binary search tree where the height difference between subtrees is at most one.” is not correct. The accepted answer is B.
