Well I, and I'm sure a lot of others, do love little code puzzles like this to solve.

I'm confused why in your desired output however the line for "d" includes "45-46" before "51-52". That's the only part of the pattern I can't wrap my brain around. Could you elaborate on that please?

EDIT: The only way that makes sense to me is if your original "file1" input had line "d" as "45-58" instead of "48-58". That or like I said, I'm missing something.
