Choose the correct description of Hash collision.
Difficulty: Medium
About this MCQ
This Medium Data Structures question asks: Choose the correct description of Hash collision. The correct choice is D. A situation in a hash table where two different keys produce the same hash value.. Read the options below, commit to one, then use the explanation to see why that choice holds and why the others do not.
Data Structures items like this one are written for Pakistan exams such as CSS, FPSC, PPSC, and NTS. The difficulty label is a hint about how much of the topic the stem assumes, not a score. Tags and exam names, when they are present, tell you where else the same idea is tested. Previous and next links stay in Data Structures so you can continue the subject. Related questions point at nearby stems if you want another angle on the same idea.
Treat the explanation as part of the question, not a footnote. If you missed it, reread the stem against the correct option before you open the next Data Structures item. A timed quiz is the same pool with a clock and a score. A past paper is a full sitting rather than this single question.
- A. A self-balancing tree data structure that maintains sorted data and allows searches, insertions, and deletions in logarithmic time, commonly used in databases.
Why not A: “A self-balancing tree data structure that maintains sorted data and allows searches, insertions, and deletions in logarithmic time, commonly used in databases.” does not fit this question. The answer is A situation in a hash table where two different keys produce the same hash value..
- B. A collision resolution technique in hashing that searches sequentially for the next open slot in the table.
Why not B: “A collision resolution technique in hashing that searches sequentially for the next open slot in the table.” does not fit this question. The answer is A situation in a hash table where two different keys produce the same hash value..
- C. A way of representing a graph using a 2D matrix where each cell indicates whether an edge exists between two vertices.
Why not C: “A way of representing a graph using a 2D matrix where each cell indicates whether an edge exists between two vertices.” does not fit this question. The answer is A situation in a hash table where two different keys produce the same hash value..
- D. A situation in a hash table where two different keys produce the same hash value. ✓
Correct answer
D. A situation in a hash table where two different keys produce the same hash value.
Explanation
A situation in a hash table where two different keys produce the same hash value option D is the accepted answer to Choose the correct description of Hash collision Option A A self-balancing tree data structure that maintains sorted data and allows searches insertions and deletions in logarithmic time commonly used in databases does not fit this question Option B A collision resolution technique in hashing that searches sequentially for the next open slot in the table does not fit this question Option C A way of representing a graph using a D matrix where each cell indicates whether an edge exists between two vertices does not fit this question.
