Dart solution

Here's my solution to start the ball rolling. In the end I incorporated my part 1 answer into the part 2 logic, and golfed the code quite a lot.

import 'package:collection/collection.dart';

var ds = '0123456789'.split('');
var wds = 'one two three four five six seven eight nine'.split(' ');

int s2d(String s) => s.length == 1 ? int.parse(s) : wds.indexOf(s) + 1;

int value(String s, List digits) {
  var firsts = {for (var e in digits) s.indexOf(e): e}..remove(-1);
  var lasts = {for (var e in digits) s.lastIndexOf(e): e}..remove(-1);
  return s2d(firsts[firsts.keys.min]) * 10 + s2d(lasts[lasts.keys.max]);
}

part1(List lines) => lines.map((e) => value(e, ds)).sum;

part2(List lines) => lines.map((e) => value(e, ds + wds)).sum;

My clojure solution

Part 2 was unexpected. Was not expecting that level of wrinkle on day 1 for sure.

I saw a few things that were guessing we might have a lot more of these sorts of twists to help throw off the AI solutions 🤷‍♂️

I'm not really happy with the repetition I have, but here's my Factor solution:

Here it is on GitHub with comments and imports.

Really cool idea! Just bad that it increases the submit time every failed attempt. I have to wait now 10 minutes on the 2nd question. + In what order?

For example: oneight CAN be 1ight or on8

Is it sorted by 1-9 or one - nine or first in word first served?

I think this is my currently issue, and i cant go through and sadly my patience of submitting every try every 10 mins has ended and i just lost it.

The delay is just so unnecessary...
