1.	The time complexity to find shortest distances by using Dijkstra’s algorithm is __________(a) O(E^2)(b) O(V+1-E)(c) O(V+E)(d) O(E+VlogV)I have been asked this question in final exam.I'd like to ask this question from Trees topic in portion Trees of Discrete Mathematics
Answer» Correct OPTION is (d) O(E+VlogV) For explanation: Time complexity of finding SHORTEST DISTANCE can be O(E + VLogV) using Fibonacci Heap. The reason is that Fibonacci Heap takes O(1) time for decrease-key OPERATION while Binary Heap takes O(logn) time.
