- 【HDU 4463 Outlets】 Minimum spanning tree （prim,kruscal All right ）
With (x,y) The form of coordinates is given n A little bit , Build roads to connect all the points ( Two of the given special points must be adjacent ), Find the minimum of the total length of all paths . Because there is no limit on the shape of the road to be built , So it can be regarded as a weighted undirected complete graph , The edge weight is the distance between two points . because ...
