Splet20. maj 2024 · But for Node 'D' and node 'E,' the path is calculated via node 'C,' and hence the weight of that vertex will be 11 and 5 because we add the weight of the edges from path A->C->D and A->C->E respectively. Now, choosing the shortest path from the above table results in choosing the node 'E' with the shortest distance of 5 from the source vertex.
