title: How do I access arrays of array in perl?
body: <p>Hi I have a array as myarray. I would like to make a list as '1 2 3' which is joining the first subarray. My string is printing the memory location I suppose instead of list. any help will be appreciated.</p>
  
  <pre><code>@myarray = [[1,2,3],[4,5,6],[7,8,9]];
  for (my $i=0; $i &lt; @myarray; $i++) {
  my @firstarray = $myarray[$i];
  my $mystring = join("", @firstarray);
  print "My string ".$mystring . ". "\n";
  }
  </code></pre>
