Well, your "agricultural" regex could be written far
much simpler, in a way even that doesn't hardcode the
number of digits:
! /(\d).*\1/
I'm a bit surprised to see an idiom in your program that another solution also used:
foreach (@array) { push @other, $_ if some_condition; }
Of course, that's much clearer, and more efficiently, written as:
@other = grep {some_condition} @array;
