About this MCQ
This Hard Data Structures MCQ checks one syllabus fact.
The question is: “What is the function or purpose of Hash table?”
The accepted answer is A. A data structure that maps keys to values using a hash function for fast lookup.. A data structure that maps keys to values using a hash function for fast lookup is the fact required by What is the function or purpose of Hash table option A Option B A linear data structure that follows the First-In-First-Out FIFO principle does not match the stem it is a near-miss used to catch incomplete recall of A data structure that maps keys to values using a hash function for fast lookup Option C A linked list where each node has pointers to both the next and previous nodes does not match the stem it is a near-miss used to catch incomplete recall of A data structure that maps keys to values using a hash function for fast lookup.
- A. A data structure that maps keys to values using a hash function for fast lookup. ✓
- B. A linear data structure that follows the First-In-First-Out (FIFO) principle.
