Thanks for the contest! :D
I liked E and G a lot, though i couldnt solve E in contest due to me bricking the implementation of string polyhashing on F before that XD.
On another note, does anyone know how to do B? All I could think of was that for some pair of adjacent ants(have an edge between them), you should never visit a node in that pair, but idk if that's on the right track.
Here is a link to the solution presentation livestream https://www.youtube.com/watch?v=S25kO1kric8
