USE JAVA PLEASE
If you need the Dijkstra code, comment and ill add it
Implement the runDJP method for implementing DJP. You will need
to use a PriorityQueue here.
Check the Dijkstra’s algorithm code on how to use it. Recall that
DJP is essentially the same as
Dijkstra’s algorithm with the only essential change being in how
the label of a node gets updated.
So, use the structure in Dijkstra’s code to write the code for DJP.
I’ll leave a few hints:
• If we remove u from the priority queue and relax an edge (u, v)
in Dijkstra’s algorithm, then
distance[v] is set to distance + edgeW eight(u, v). In DJP, on
the other hand, we will set
label[v] = edgeW eight(u, v).
• Also, we need to retrieve the edges of the MST at the end. To
this end, we use an array
(of type Edge) where we will store the edges of the minimum
spanning tree. Call this array
parent[ ]. Suppose, we relax an edge (u, v) and we set label[v] =
edgeW eight(u, v), then you
will update parent[v] = e.
• At the end, parent[ ] array contains all the edges of the
spanning tree. So, you collect them
in a dynamic array and the return the dynamic array.
