Implementation of Prim's algorithm for finding minimum spanning tree using Adjacency list and min heap with time complexity: O(ElogV). Assuming the arbitrary vertex to start the algorithm is B, we have three choices A, C, and E to go. To add more to this, the Minimum Spanning Tree or MST, is an application of Disjoint Data Structure. In the standard template library available in c++, we have a data structure called priority queue which functions in a similar manner to the heaps. While adding an edge take care that the one end of the edge … Some of the features of this code are – The Adjacency List used is exactly as in Adjacency List using C++ STL; The Min Heap is unchanged from the former post on Prim’s Algorithm.
