It starts out at node 6 and runs through all the neighboring nodes and determines which is shorter using a “greedy” mechanism. It goes for the least cost (the shortest path to get one more node closer to the destination). In our example node 6 has only one path, to node 4 so that is a given. granit box

We need to maintain the path distance of every vertex. We can store that in an array of size v, where v is the number of vertices. We also want to be able to get the shortest path, not only know the length of the shortest path. For this, we map each vertex to the vertex that last updated its path length. Once … See more Dijkstra's Algorithm works on the basis that any subpath B -> D of the shortest path A -> Dbetween vertices A and D is also the shortest … See more The implementation of Dijkstra's Algorithm in C++ is given below. The complexity of the codecan be improved, but the abstractions are convenient to relate the code with the algorithm.
