I need to compare the following arrays, compare them all
and output the comparisons to the screen:

my @D = (0, 1, 2, 3, 4, 5, 6, 7, 8, 9);<br>
my @E = qq(a b c d e f g h i j k l m n o p q r s t u v w x y z);<br>
my @F = (1, 3, 5, 7, 9);<br>
my @G = qq(a b c d e f g h i j k l m);<br>
my @H = (2, 4, 6, 8);<br>
my @K = qq(n o p q r s t u v w x y z);<br>
my @M = (0, 1, 2, 3, 4, 5, 6, 7, 8, 9);<br>
my @P = qq(a b c d e f g h i j k l m n o p q r s t u v w x y z);<br>
my @S = (1, 3, 5, 7, 9);<br>
my @T = qq(a b c d e f g h i j k l m);<br>
my @x = (2, 4, 6, 8);<br>
my @Z = qq(n o p q r s t u v w x y z);<br>

I have so far:

use warnings;<br>
use strict;<br>
use diagnostics;<br>
# use carp;<br>
<br>
sub check_same (\@\@);<br>
<br>
my @D = (0, 1, 2, 3, 4, 5, 6, 7, 8, 9);<br>
my @E = qq(a b c d e f g h i j k l m n o p q r s t u v w x y z);<br>
my @F = (1, 3, 5, 7, 9);<br>
my @G = qq(a b c d e f g h i j k l m);<br>
my @H = (2, 4, 6, 8);<br>
my @K = qq(n o p q r s t u v w x y z);<br>
my @M = (0, 1, 2, 3, 4, 5, 6, 7, 8, 9);<br>
my @P = qq(a b c d e f g h i j k l m n o p q r s t u v w x y z);<br>
my @S = (1, 3, 5, 7, 9);<br>
my @T = qq(a b c d e f g h i j k l m);<br>
my @x = (2, 4, 6, 8);<br>
my @Z = qq(n o p q r s t u v w x y z);<br>
print "\@D is not the same as \@E" if check_same (@D,@E,@F,@G,@H,@K,@M
+,@P,@S,@T,@X,@Z);<br>
print "\@D is the same as \@F" if check_same (@D,@E,@F,@G,@H,@K,@M,@P,
+@S,@T,@X,@Z);<br>
<br>
<br>
sub check_same (\@\@) {<br>
   my ($ref_one, $ref_two,) = @_;<br>
   # same size?<br>
   return 0 unless @$ref_one == @$ref_two;<br>
   for my $elem (0..$#$ref_one) {<br>
      return 0 unless $ref_one->[$elem] eq $ref_two->[$elem];<br>
   }<br>
   # same if we got this far<br>
   return 1;<br>
}<br>
