Yeah I was sort of lucky that my edge case was on the last line, still took a full hour of wondering why my solution was wrong though.

I find some problems of AoC are sometimes on the thin line between "it's interesting and I might learn something new" vs "wasting my time with under-specified or ambiguous problem specs".. Part 2 of Day 1 lies dangerously in the latter, for me.

What was this edge case you encountered? My code worked...after I finally read the problem closely enough.

For me it was a lack of specific instructions on how to handle overlaps. The edge case that frustrated me for a while was "oneight" at the end of a line. My initial code made it look like this "1ight", when it should have been "18".

When searching for the last number in the line I just reversed the line and scanned through it looking for the reversed strings for the number:

one -> eno

two -> owt

three -> eerht

etc

It makes the entire solution extremely simple, though a little verbose.
