What is the time complexity of Floyd–Warshall algorithm to calculate all pair shortest path in a graph with n vertices?
(A)
O(n2log(n))
(B)
Theta(n2log(n))
(C)
Theta(n4)
(D)
Theta(n3)
Answer: (D)
Explanation:
Floyd–Warshall algorithm uses three nested loops to calculate all pairs shortest path. So, the time complexity is Theta(n3).
