Hello Monks,

I just have a quick question and I can't believe I can't figure it out on my own. I'm working on a simple word game, and what I need perl to do is open up a dictionary file (I've already limited the dictionary wordlist to 6 letter words) and then based on a given 6 character input, output all words from the dictionary list that can be made from those letters, of course in any order.

What I have right now just for testing the code snippet... 
use strict;
use warnings;

my $input = <STDIN>;
my @inputarray = split('',$input);

my $file = 'wordlist.txt';
open(INFO, $file);
my @lines = <INFO>;
close(INFO);

my $tacobell;
foreach $tacobell (@lines) {
    if ($tacobell =~ /$inputarray[0]$inputarray[1]$inputarray[2]$input
+array[3]$inputarray[4]$inputarray[5]/) {
        print $tacobell;
    }
    
}

exit();

After having read through about 15 regex tutorials, I'm sure there's an easy way to do this, I just can't figure it out. I think my code looks for the sequence of characters in that order ... I just need it from any order.

Also, I know there are some different ways of formatting regex to decrease cpu time where you don't have to recalculate certain things, so hopefully if there's a solution to this problem it'll be somewhat cpu friendly :)

I'd appreciate any help yall can offer!

Thanks,
Alan
