Consider the Bellman-Ford algorithm with FIFI queue. What is the running time of the whole Bellman-Ford algorithm, if the queue is (correctly but inefficiently) implemented in such a way that one DEQUEUE operation takes O(n) time? (2 marks for the correct answer, -1 marks for an incorrect answers, O marks for no answer) O 0(mn); O Omn log n), but not necessarily O(mn); O 0(mn), but not necessarily O(mn); O 0(mn), but not necessarily O(mn)
