Topological sort is best defined as which of the following?
Difficulty: Medium
About this MCQ
This Medium Algorithms question asks: Topological sort is best defined as which of the following? The correct choice is C. An ordering of vertices in a directed acyclic graph such that for every edge, the source vertex comes before the destination vertex.. 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 sorting algorithm that repeatedly selects the smallest remaining element and moves it to its correct position.
Why not A: “A sorting algorithm that repeatedly selects the smallest remaining element and moves it to its correct position.” does not fit this question. The answer is An ordering of vertices in a directed acyclic graph such that for every edge, the source vertex comes before the destination vertex..
- B. A sorting algorithm that builds the final sorted array one element at a time by inserting each element into its correct position.
Why not B: “A sorting algorithm that builds the final sorted array one element at a time by inserting each element into its correct position.” does not fit this question. The answer is An ordering of vertices in a directed acyclic graph such that for every edge, the source vertex comes before the destination vertex..
- C. An ordering of vertices in a directed acyclic graph such that for every edge, the source vertex comes before the destination vertex. ✓
- D. A comparison-based sorting algorithm that uses a binary heap data structure to sort elements.
Why not D: “A comparison-based sorting algorithm that uses a binary heap data structure to sort elements.” does not fit this question. The answer is An ordering of vertices in a directed acyclic graph such that for every edge, the source vertex comes before the destination vertex..
Correct answer
C. An ordering of vertices in a directed acyclic graph such that for every edge, the source vertex comes before the destination vertex.
Explanation
An ordering of vertices in a directed acyclic graph such that for every edge the source vertex comes before the destination vertex option C is the accepted answer to Topological sort is best defined as which of the following Option A A sorting algorithm that repeatedly selects the smallest remaining element and moves it to its correct position does not fit this question Option B A sorting algorithm that builds the final sorted array one element at a time by inserting each element into its correct position does not fit this question Option D A comparison-based sorting algorithm that uses a binary heap data structure to sort elements does not.
