In this problem statement, we have assumed the source vertex to be ‘0’. If a vertex is unreachable from the source node, then return -1 for that vertex. Example 1: SpletOne algorithm for finding the shortest path from a starting node to a target node in a weighted graph is Dijkstra’s algorithm. The algorithm creates a tree of shortest paths from the starting vertex, the source, to all other points in the graph.

Shortest path problem - Wikipedia

SpletFind the shortest path between node 1 and node 5. Since several of the node pairs have more than one edge between them, specify three outputs to shortestpath to return the specific edges that the shortest path traverses.
