Megathread guidelines
- Keep top level comments as only solutions, if you want to say something other than a solution put it in a new post. (replies to comments can be whatever)
- You can send code in code blocks by using three backticks, the code, and then three backticks or use something such as https://topaz.github.io/paste/ if you prefer sending it through a URL

I initially thought that, but now I reconsider I’m not so sure. Isn’t it possible to have a 3-member clique overlapping two larger ones? In other words, there could be more than one way to partition the graph into completely connected components. Which means my solution to part 2 is technically incorrect. Bummer.
There probably are multiple ways to partition the graph. I haven’t applied any optimizations and my program checks members of already detected groups again, would that yield all possible partitions because I choose all the possible starting points for a k-clique?
