Use a vector of edges which consist of all the edges in the graph and each item of a vector will contain 3 parameters: source, destination and the cost of an edge between the source and destination. It is a greedy algorithm in graph theory as it finds a minimum spanning tree for a connected weighted graph adding increasing cost arcs at each step. It falls under a class of algorithms called greedy algorithms which find the local optimum in the hopes of finding a global optimum.We start from the edges with the lowest weight and keep adding edges until we we reach our goal.The steps for implementing Kruskal's algorithm are as follows: 1.
