WebThe Floyd Warshall algorithm is for finding the shortest path between all the pairs of vertices in a weighted graph; the algorithm works for both directed and undirected graphs. This algorithm is asked directly in an interview, or the interviewer may give you a real-life situation and will ask you to solve it using graphs. WebMay 6, 2013 · Add a comment. 1. Wikipedia has some good info and pseudocode. Basically you just fill a V x V 'next' matrix where element i,j contains the index of the vertex you need to go to to get from node i to node j. The shortest path from i to j can then be gives as the path from i to next [i] [j] and from next [i] [j] to j.
