About this MCQ
This Hard Data Structures MCQ checks one syllabus fact.
The question is: “What does B-tree refer to?”
The accepted answer is A. A self-balancing tree data structure that maintains sorted data and allows searches, insertions, and deletions in logarithmic time, commonly used in databases.. B-tree refers to a self-balancing tree data structure that maintains sorted data and allows searches, insertions, and deletions in logarithmic time, commonly used in databases.
- A. A self-balancing tree data structure that maintains sorted data and allows searches, insertions, and deletions in logarithmic time, commonly used in databases. ✓
- B. A matrix in which most of the elements are zero, often stored using specialized structures to save memory.
Why not B: “A matrix in which most of the elements are zero, often stored using specialized structures to save memory.” is not correct. The accepted answer is A. A self-balancing tree data structure that maintains sorted data and allows searches, insertions, and deletions in logarithmic time, commonly used in databases.. B-tree refers to a self-balancing tree data structure that maintains sorted data and allows searches, insertions, and deletions in logarithmic time, commonly used in databases.
- C. A data structure that allows insertion and removal of elements from both the front and the back.
Why not C: “A data structure that allows insertion and removal of elements from both the front and the back.” is not correct. The accepted answer is A. A self-balancing tree data structure that maintains sorted data and allows searches, insertions, and deletions in logarithmic time, commonly used in databases.. B-tree refers to a self-balancing tree data structure that maintains sorted data and allows searches, insertions, and deletions in logarithmic time, commonly used in databases.
- D. An array-like data structure that automatically resizes itself as elements are added or removed.
Why not D: “An array-like data structure that automatically resizes itself as elements are added or removed.” is not correct. The accepted answer is A. A self-balancing tree data structure that maintains sorted data and allows searches, insertions, and deletions in logarithmic time, commonly used in databases..
