In the exercise, the format had to be "4 *sets of 4 digits separated by
dashes or blanks*". The expression you wrote would clean up things like:
"01234 bonjour 5 madame! 67 December 8 9012 3 4 5
..".gsub(/[^0-9]/, "")
=> "0123456789012345"
However, it is a first approximation, and I would not obsess on this now, if
you want to catch up with the course. Regular expressions are a (splendid)
language apart, that you can pick up later (spending a couple of weeks of
serious work on them).
