Not only replacing didn't work. I did it as a regex, but Rusts regex crate only supports non-overlapping matches.
Python's
realso only supports non-overlapping matches and only one direction, so what I did wasspoiler
I looked for the first digit/word using the regex. Then for the last digit/word, I inverted the string and the regex (so I was matching the words eno, owt, eerht, etc.) and took the first occurence, and inverted that in case it was a word, and then I had my last digit. I just had to pay attention to only include the|\dafter inverting the regex, sinced\|is not right.Oh, nice.
I just replaced those compounded words with their non-overlapping counterparts.
Oh, cool, I did pretty much the same thing, just finding the words manually instead (didn’t want to use any external libraries, so I just wrote a function to search for me. Haskell doesn’t have much for OOT B functionality).
