Which statement correctly explains Depth-first search (DFS)?
Difficulty: Medium
About this MCQ
This Medium Algorithms question asks: Which statement correctly explains Depth-first search (DFS)? The correct choice is D. A graph traversal algorithm that explores as far as possible along each branch before backtracking.. 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 splits the array, sorts each half, and merges them.
Why not A: “A divide-and-conquer sorting algorithm that splits the array, sorts each half, and merges them.” does not fit this question. The answer is A graph traversal algorithm that explores as far as possible along each branch before backtracking..
- B. A divide-and-conquer sorting algorithm that partitions elements around a pivot value.
Why not B: “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 as far as possible along each branch before backtracking..
- C. A measure of the amount of time an algorithm takes to run as a function of input size.
Why not C: “A measure of the amount of time an algorithm takes to run as a function of input size.” does not fit this question. The answer is A graph traversal algorithm that explores as far as possible along each branch before backtracking..
- D. A graph traversal algorithm that explores as far as possible along each branch before backtracking. ✓
Correct answer
D. A graph traversal algorithm that explores as far as possible along each branch before backtracking.
Explanation
A graph traversal algorithm that explores as far as possible along each branch before backtracking is the term that matches Which statement correctly explains Depth-first search DFS option D Option A A divide-and-conquer sorting algorithm that splits the array sorts each half and merges them does not fit this question Option B A divide-and-conquer sorting algorithm that partitions elements around a pivot value does not fit this question Option C A measure of the amount of time an algorithm takes to run as a function of input size does not fit this question For this Algorithms question the accepted answer is A graph traversal algorithm that explores as far as.
