Prim's algorithm for finding the minimum spanning tree relies on a greedy approach. A greedy approach is defined as an algorithm paradigm where we try to find the global optimal solution by considering the local optimal solution at each stage. We will explore greedy algorithms in Chapter 11, Solve Problems with Advanced Techniques. In a greedy approach, the algorithm creates subsets of edges and finds out the least costly one from the subset of edges. This subset of edges will include all vertices. It starts from an arbitrary position and grows the tree one vertex at a time by choosing the cheapest possible connection between the vertices. Let's consider the following graph:
Now, we will apply a very basic version of Prim's algorithm to get the minimum spanning tree as well as the minimum cost or weight...
