What is the main advantage of Warshall's algorithm over the naive method?
💡 Hint: Think about how the running time compares when processing large matrices.
True or False: In Warshall's algorithm, if there’s a path from node A to node B, it implies A can reach B through any intermediate nodes.
💡 Hint: Remember the definition of intermediate nodes.
