Merge sort is best defined as which of the following?
Difficulty: Medium
About this MCQ
This Medium Algorithms question asks: Merge sort is best defined as which of the following? The correct choice is B. A divide-and-conquer sorting algorithm that splits the array, sorts each half, and merges them.. Read the options below, commit to one, then use the explanation to see why that choice holds and why the others do not.
Algorithms 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 Algorithms 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 Algorithms 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. An algorithmic technique that solves problems by breaking them into overlapping subproblems and storing results.
Why not A: “An algorithmic technique that solves problems by breaking them into overlapping subproblems and storing results.” does not fit this question. The answer is A divide-and-conquer sorting algorithm that splits the array, sorts each half, and merges them..
- B. A divide-and-conquer sorting algorithm that splits the array, sorts each half, and merges them. ✓
- C. A mathematical notation used to describe the upper bound of an algorithm's time or space complexity.
Why not C: “A mathematical notation used to describe the upper bound of an algorithm's time or space complexity.” does not fit this question. The answer is A divide-and-conquer sorting algorithm that splits the array, sorts each half, and merges them..
- D. An algorithmic approach that makes the locally optimal choice at each step, hoping to find a global optimum.
Why not D: “An algorithmic approach that makes the locally optimal choice at each step, hoping to find a global optimum.” does not fit this question. The answer is A divide-and-conquer sorting algorithm that splits the array, sorts each half, and merges them..
Correct answer
B. A divide-and-conquer sorting algorithm that splits the array, sorts each half, and merges them.
