@prologic@twtxt.net That is a lot of code, yes. 😅 Mine is shorter, has more naive searching (it searches a word like red and then backtracks to the number before it; completely ignoring the semi-colons because they don’t matter), and – like any good C program – will crash horribly on malformed input. 👌😂🥴

It really depends on what you’re after. I’d never write code like this in “real-world applications”. But for these puzzles and my DOS use case, it’s “good enough”. 😅
