In section 14.7.1, according to the Java Code Fragment 14.15, implement Prim-Jarnk algorithm for the MST problem, reappear the example in Figure 14.20 and 14.21. Your program should print out all the graphs in Figure 14.20 and 14.21.

Algorithm PrimJarnik (G) : Input: An undirected, weighted, connected graph G with n vertices and m edges Output: A minimum spanning tree T for G Pick any vertex s of G D[s]=0 for each vertex v=s do D[v]= Initialize T=. Initialize a priority queue Q with an entry (D[v],v) for each vertex v. For each vertex v, maintain connect (v) as the edge achieving D[v] (if any). while Q is not empty do Let u be the value of the entry returned by Q.removeMin( ). Connect vertex u to T using edge connect (e). for each edge e=(u,v) such that v is in Q do \{check if edge (u,v) better connects v to T} if w(u,v)
