WebStep-by-step explanation. Question:Use Djikstra's shortest-path algorithm to compute the shortest path from C to all other network nodes. Show how the algorithm works by filling up the table below. Here, D (X) means the distance from the source to a node X, and p (X) means the parent of a node X in the computed path tree. WebThe shortest route (in terms of cost) between any two nodes in a graph may be discovered using either the Dijkstra's method or the Prim algorithm. Both methods search for the shortest route by moving around the network and investigating (or attaching) nodes.
