What is Breadth-first search (BFS) primarily used for?
Difficulty: Medium
About this MCQ
This Medium Algorithms question asks: What is Breadth-first search (BFS) primarily used for? The correct choice is C. A graph traversal algorithm that explores all neighbors at the current depth before moving deeper.. 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. A divide-and-conquer sorting algorithm that partitions elements around a pivot value.
Why not A: “A divide-and-conquer sorting algorithm that partitions elements around a pivot value.” does not fit this question. The answer is A graph traversal algorithm that explores all neighbors at the current depth before moving deeper..
- B. An algorithmic technique that solves problems by breaking them into overlapping subproblems and storing results.
Why not B: “An algorithmic technique that solves problems by breaking them into overlapping subproblems and storing results.” does not fit this question. The answer is A graph traversal algorithm that explores all neighbors at the current depth before moving deeper..
- C. A graph traversal algorithm that explores all neighbors at the current depth before moving deeper. ✓
- D. An algorithmic technique that incrementally builds candidates and abandons ones that fail to satisfy constraints.
Why not D: “An algorithmic technique that incrementally builds candidates and abandons ones that fail to satisfy constraints.” does not fit this question. The answer is A graph traversal algorithm that explores all neighbors at the current depth before moving deeper..
Correct answer
C. A graph traversal algorithm that explores all neighbors at the current depth before moving deeper.
Explanation
