WebJul 6, 2024 · 3. You don't need that availability check to do a topological sort with DFS. DFS itself ensures that you don't leave a node until its children have already been processed, so if you add each node to a list when DFS finishes with it, they will be added in (reverse) topological order. Don't forget to do the whole graph, though, like this: def ...
