MODERATORS
I try to use
Vecs instead ofHashSets and maps whenever the key domain is reasonably small (just the grid in this case), simply because in the end direct memory access is a lot faster than always hashing values.But looking at this case again, it is certainly a lot easier to have just
antinodes.len()at the end instead of counting all true values. This datastructure is also not really performance-critical, so aHashSetis probably the cleaner choice here.
