Kruskal's Algorithm Implementation in CThis code, titled "Kruskal.c," is a C program that implements Kruskal's algorithm for finding the minimum spanning tree in an unconnected graph. It is copyrighted by ctu_85 and highlighted by yzfy. The algorithm starts by taking the number o...

Kruskal使用前向星和并查集实现,可以存储重边(平行边),时间复杂度是O(m log m + m),m是边的数量。 Prim使用邻接矩阵建图,不可以存储重边(平行边),如果出现重边,存储的是权值最小的那一条,时间复杂度为O(n*n), n是顶点的数量。使用邻接表建图可能会提高效率。 一般情况下,题目都是比较裸的。难度为易。
