WebPrim’s Minimum Spanning Tree algorithm works well on the dense graph but fails when the graph is disconnected. The algorithm has a runtime of O (E*log (E)) (lazy) which can be optimized (eager) to make it more time efficient.

You start at vertex 0, and you see that the closest vertex to 0 is 2.
