J
Today’s the first one where I feel like the choice of language is a disadvantage without compensating advantages. Or, at least, I don’t know J well enough yet to use its compensating advantages for this kind of task, so what I end up with is Python 2 with obscure syntax and no associative data structures.
Also, I can’t post my code, because apparently Lemmy is interpreting some of today’s bizarre line noise as hostile and sanitizing it. It looks more or less like the other imperative solutions here, just with more punctuation.
