🐶🐾 Very nice work, Andrea! I left a couple comments on the time complexity and an edge case. Let me know what questions you have.

⏱ Time complexity would actually be O(N + E) where N is the number of nodes (aka dogs) in the graph and E is the number of edges (dislike between two dogs) in the graph represented by dislikes. This is because you visit each edge and each node exactly once.

Imagine a graph that has multiple disconnected nodes stored at the beginning of the adjacency list dislikes. How might you refactor your code to account for this edge case?
