I found this really tough for a day 1 problem. Because I don't really know regex, I did not know the secret to finding overlapping patterns. I quickly figured out that "twone" was a possibility, because it was in the example, but then I had to find other examples and hardcode them into my split pattern.
This isn't general, my input doesn't have 'sevenine' for example.
Abso-fucking-lutly. I just find sharing a link easier than wrangling code blocks.
There are also hipster "forges" like Sourcehut, if that's your jam.
absolutely — removing my dependency on GitHub has actually been a blocker on me releasing code lately, and it’s something I want to tackle when we launch that open source community. if it helps collaboration, I can provide some ultra-janky git hosting on awful.systems with the same service that hosts our infrastructure code, though this’d be just basic git and gitweb with ssh public key auth
fuck yes scheme. you might have just inspired me to write some Lisp Machine Lisp solutions, since I might need a Lisp Machine codebase to test one of my side projects
Re Perl findall, I used this regex in my "clean" solution which I didn't post because I figure it's more honest to submit what worked, not the smart stuff you found out later.
regex
# find all numerals and number in English from the string $line and put them into the array @spelled my @spelled = ( $line =~ (m/(?=(\d{1}|one|two|three|four|five|six|seven|eight|nine))/g );I like your condensed solve method, yay for concise code
