可以进一步优化:由于find的复杂度为树的高度,那么并的时候以更高的树的Root为Parent则可以减少find的复杂度。 1/**2* Definition for a Connection.3* public class Connection {4* public String city1, city2;5* public int cost;6* public Connection(String city1, String city2, int cost) {7* this...

Definition 2 (Minimum Spanning Tree): Consider an edge-weighted, connected, undirected graph G = (V, E). The minimum spanning tree T = (V, E') of G is the spanning tree that has the smallest total cost. The total cost of T means the sum of the weights on all the edges in E'...
Use the Kruskal algorithm to find the minimum spanning tree by sorting the edges and picking edges from ones with smaller weights. 提示2 Use a disjoint set to avoid adding redundant edges that result in a cycle. 提示3 To find if one edge is critical, delete that edge and re-run the...
最小生成树(Minimum Spanning Tree - MST): 学习 Prim 算法和 Kruskal 算法。理解它们的贪心策略和如何保证生成树的权值和最小 17。 拓扑排序 (Topological Sort): 用于有向无环图 (DAG) 的顶点排序,使得所有有向边都从前面的顶点指向后面的顶点。可以通过 Kahn 算法 (基于 BFS) 或基于 DFS 实现 17。
For each test case, you must output exactly 2 lines. You must print the weight of the minimum spanning tree in the 1st line. In the 2nd line, you must print N-1 space-separated integers f2, f3, … , fN, implying there is an edge between i and fi in your tree(2<=i<=N). If...
