throop has asked for the wisdom of the Perl Monks concerning the following question:
Perl monks,
I, a pilgrim, seek deeper insight to things Perl.
There are certain operations on arrays for which most programming languages have functions, but for which Perl does not. There are instructions on how to do these things in the perldoc, but they aren't core functions:
- Getting the maximum or minumum element in an array of numbers;
- Getting the union, intersection or difference of two arrays.
