SpletThe numbers beside the vertices indicate the distance from the root vertex. In mathematics and computer science, a shortest-path tree rooted at a vertex v of a connected, undirected graph G is a spanning tree T of G, such that the path distance from root v to any other vertex u in T is the shortest path distance from v to u in G .

Splet2. A generic scheme to make an undirected graph directed is to replace each of its edges by two directed edges with same weight as the original weight of the edge. For an undirected edge ( u, v). Replace it by two directed edges ( u, v) (direction u to v) and ( v, u) (direction v to u). The weight of both of these edges are same as weight of ...

Splet29. avg. 2024 · Given an unweighted and undirected graph, can I identify the second best shortest path from every node to every other node in polynomial time? When I say the second best, as long as one edge is different than the edges existing in the first shortest path, it is acceptable. This also implies that the length of the paths can be equal. SpletEditorial Given an undirected graph and a starting node, determine the lengths of the shortest paths from the starting node to all other nodes in the graph. If a node is unreachable, its distance is -1. Nodes will be numbered consecutively from to , and edges will have varying distances or lengths.

SpletYou are given a connected, undirected graph with ‘V’ vertices and ‘E’ edges. You are provided with two vertices, ‘src’ and ‘dest’. Your task is to return the shortest distance between the given vertices ‘src’ and ‘dest’. For Example: For the given graph, The shortest distance between 1 and 3 is 2 (via 1 <-> 2 <-> 3).
