Floyd-Warshall All-Pairs
Shortest paths between every pair.
Every Pair at Once
Sometimes you need the shortest path between every pair of nodes, not just from one source. That is the all-pairs problem.
Meet Floyd-Warshall
Floyd-Warshall fills a full distance table for all pairs with three tidy nested loops and almost no setup.
