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 MCQ checks one syllabus fact.
The question is: “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 accepted answer is C. Topological sort. 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 is answered by Topological sort option C Option A Memoization does not match the stem it is a near-miss used to catch incomplete recall of Topological sort Option B Selection sort does not match the stem it is a near-miss used to catch incomplete recall of Topological sort Remaining alternatives Bellman-Ford algorithm fall outside the same rule and should be eliminated once Topological sort is identified Algorithms questions of this type reward precise definitions rather than approximate associations Algorithms recall of this distinction is a regular item in FPSC PPSC NTS and.
- A. Memoization
Why not A: “Memoization” is not correct. The accepted answer is C. Topological sort. 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 is answ
- B. Selection sort
Why not B: “Selection sort” is not correct. The accepted answer is C. Topological sort. 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 is answ
- C. Topological sort ✓
- D. Bellman-Ford algorithm
Why not D: “Bellman-Ford algorithm” is not correct. The accepted answer is C. Topological sort. 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 is answ
