Identify the correct concept described as: an ordering of vertices in a directed acyclic graph such that for every edge, the source vertex comes before the destination vertex.
Difficulty: Medium
About this MCQ
This Medium Algorithms question asks: Identify the correct concept described as: an ordering of vertices in a directed acyclic graph such that for every edge, the source vertex comes before the destination vertex. The correct choice is C. Topological sort. 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. Memoization
Why not A: “Memoization” does not fit this question. The answer is Topological sort.
- B. Selection sort
Why not B: “Selection sort” does not fit this question. The answer is Topological sort.
- C. Topological sort ✓
- D. Bellman-Ford algorithm
Why not D: “Bellman-Ford algorithm” does not fit this question. The answer is Topological sort.
Correct answer
C. Topological sort
