in reply to regexp golf - homework

Ehm ... what am I missing here? like IMHO just searching for a repeated digit like with /(\d).*\1/ and inverting the result should do.

DB<111> print $_ !~ /(\d).*\1/ ? "$_ ok\n" :"$_ has <$1>\n" for qw/0 +12 0102 01233/ 012 ok 0102 has <0> 01233 has <3>

Cheers Rolf
