To explain this approach, we will use the Floyd-Warshall algorithm, which is one of the most commonly used algorithms for finding all-pairs shortest paths. The Floyd-Warshall Algorithm The Floyd-Warshall algorithm uses a dynamic programming approach to find the shortest distance between all pairs of nodes in a graph.
