Question

Implement a minimum spanning tree (MST) algorithm using C++. An MST (also minimum weight spanning tree) is a subset of the edges of a connected, edge-weighted, undirected graph that connects all the vertices together, without any cycles and with the minimum total edge weight. The program is interactive. Graph edges with respective weights are entered at the command line and results are displayed on the console.
