Here, E and V represent the number of edges and vertices in the given graph respectively. Sorting of all the edges has the complexity O(ElogE). After sorting, we apply the find-union algorithm for each edge.

WebThe convention of using colors originates from coloring the countries of a map, where each face is literally colored. This was generalized to coloring the faces of a graph embedded in the plane.
