Re^2: extracting all possible n-mers from an array

in reply to Re: extracting all possible n-mers from an array
in thread extracting all possible n-mers from an array

for some reason i immediately thought of colour pallettes.
not the nicest code, but something i knocked up quickly using your algorithm:

my $c;
my $cols={map{(chr(65+$c++),sprintf "%02x",$_)}(0, 51, 102, 153, 204, 
+ 255)};
my @letters=qw/A B C D E F/;

print "<html><body><table border=1><tr>";
$c=0;
for(glob "{@{[ join ',', @letters ]}}" x 3){
s#.#$cols->{$&}#eg;

print "<td bgcolor='#$_'>&nbsp;</td>\n";
print "</tr><tr>" if !(++$c %9);
};
print "</tr></table></body></html>";
