Thanks, this is super helpful. I have one other question, in
the solution you posted and also the one I posted in the
discord today. I was required to use byLineCopy. I first used
byLine but I for some reason that I can't really explain only
got the last line from that. I switched to byLineCopy because I
saw it in other peoples solution and that magically fixed all
problems I had. What exactly happened here?
byLine reuses the buffer. So it is only valid while you haven’t
fetched the next line.
byLineCopy makes a copy of the line to give you so it will always
remain valid.
In these simple small type problems I find it easier to just
fetch the whole file into a string and work with that. The
performance of parsing the input is negligible.
