Which of the following algorithm can be used to efficiently calculate single source shortest paths in a Directed Acyclic Graph?
(A) Dijkstra
(B) Bellman-Ford
(C) Topological Sort
(D) Strongly Connected Component
Answer: (C)
Explanation: Using Topological Sort, we can find single source shortest paths in O(V+E) time which is the most efficient algorithm. See following for details.
