In this situation, I usually use a hash instead of an array so I can
create highly useful statistics of how often each value occurs.
So I would do:
$hash{a}++ or $hash{b}++ or $hash{c}++
And then, like Jeff said, you could look in the manpage and get your
array from this hash you've created using the keys function like so:
@array = keys %hash;
