I really hate how GMail line wraps without giving you a chance to
preview before sending.
Here's a version of parse that shouldn't line wrap. It also more

You'll want to take a look at the docs for c.c.string[1], so have that
open in another tab. Anyway, let's assume you have the data in a file
mytext.txt
First, load the raw data with the slurp fn
user=>(def raw-string (slurp "mytext.txt"))
Next, you'll want to use the split-lines fn to create a

(take (Integer/parseInt (.readLine r)) (repeatedly
