I was toying with
Pattern Finding problem posted by
artist and came up with a solution that I thought might make an interesting obfu. Read that thread to what its supposed to do (especially the updated rules)
use integer;$"="|";$\="\n";$S='Just Another Happy Perl Hacker';$C=5;$L
+=
length($S);%0=();sub o{$l=shift;return 1 if(exists($0{"@$l"}));$0{"@$l
+"
}++;@n=0..$#$l;for$i(@n){for(@n){next if$i==$_;return 1 if index($$l[$
+i
],$$l[$_])!=-1}}0}@1=map{$_*length($S)/$C}0..$C-1;$.=0;while($.++<$L*1
+00
){@0=();for(0..$C-1){my$str=($_==$C-1)?substr($S,$1[$_]):substr($S,$1[
+$_
],$1[$_+1]-$1[$_]);push@0,$str;}$.=0,print"@0" unless(o(\@0));$;=rand(
+@1
-1)+1;$1[$;]+=(rand(3)>1)?-1:1;$1[$;]=0 if$1[$;]<0;$1[$;]=$L-1 if$1[$;
+]
>=$L;$1[$;]=$1[$;-1]+1 if$;>0&&$1[$;]<=$1[$;-1];$1[$;]=$1[$;+1]-1 if$;
+<
$C-2&&$1[$;]>=$1[$;+1];}
