I think you meant to link to this Solution ;)

Not the best solution as it is not fast at all. It also reveals something interesting: in debug mode (cargo test) HashSet is noticeably slower than BTreeSet, but in release mode (cargo test --release) it runs as well, if not slightly better. Code

It was driving me nuts that I couldn't get BFS right. Then I re-copy-pasted the input and it worked. Moral of story: Sometimes it is the input not me. Part 2 owes special thanks to u/Boojum and u/theadamabrams for their super helpful visualizations. Code

This is straightforward. Now I can eat my breakfast.

Quickly realized there must be a loop somewhere and scratching my head to detect it. Then browsing this sub revealed that loops don't start in the middle. That directly pushed part 2 to LCM. Code

Almost hand-rolled every combination in part 2 before doing substitutions. And so much boilerplate to satisfy sorting requirements.

Part 2 takes a while, but it's a hiccup while which is totally acceptable to me. Code
