Kruskal is a greedy algorithm for finding the minimum spanning tree with the least (or maximum cost). This algorithm will create spanning tree with minimum weight, from a given weighted graph. The algorithm is as follows: Sort all the weights in ascending or descending order. We have not added this optimization to keep code simple. Unlike Prim’s algorithm, which grows a tree until it spans the whole vertex set, Kruskals algo-rithm keeps a collection of trees (a forest) which eventually gets connected into one spanning tree. In this article, we'll use another approach, Kruskal’s algorithm, to solve the minimum and maximum spanning tree problems. Sort all the edges in non-decreasing order of their weight.
