It could have been more clear. The wording from the problem is "the last digit on each line". To me, that pretty clearly implies "the rightmost substring containing a digit", but I guess I can see how someone could question that interpretation.
- bcrosby95 3y agoI think it strongly implies a direction with the example in part 1 where there's only a single digit resulting in "77" rather than "7".
- philomath_mn 3y agoRight, but we read the word "eight" from left to right -- to me it is non-obvious that "eightwo" should be counted as two digits when (a) there aren't enough characters to actually make both digits and (b) there wasn't a single example showing this overlap expanded But I suppose can see the other side as well: the wording makes it sound like any spellings of those digits _counts_ as a digit rather than should be _replaced_ by a digit. However I think the ambiguity here made the puzzle more difficult in a non-fun way.
