I have a list of strings that start with an uppercase B, Q, or Z
I need to sort them so they are in order of Q, B , then Z
Any ideas or input on how to efficiently do that with sort() or
even map() is most appreciated :) perldoc -f sort|-f map didn't
appear to address this situation :(
I would use map() before and after sort() to "correct" leading
characters.
my @sorted =
map { tr/123/QBZ/; $_ }
sort
map { tr/QBZ/123/; $_ }
@data;
There's a potential gotcha there: since all Qs and Bs are being
swapped lexicographic order after the first character is also
changed. That might not be an issue though.
