An explanation of common notations of area codes would be nice for us non-Americans :)
I (as French) Agree. A Wikipedia link which would explain supported area codes is definitely missing.
"You can assume the first three digits of a ten-digit number will always be the area code." Hmmm.... too bad there was no explanation applying to telephone numbers with more (or less?) than ten digits.
The problem fails to mention that the area codes should be sorted, and that phone numbers may have country codes.
Apparently the order needs to be the same as that defined by the test suite; which is not in the order of the phone numbers given :(
Is there a way to execute regexp/regexprep with multiple expresssions at the same time?
Not sure what's going on here, but it works in my actual MATLAB program, and Octave.
