Well. Let's open a box/element from array1, and check the box's/elements in array2. If the box's are the same, cross them off the list and don't worry about them again.

use strict;

my @arrayone = ('a','b','c','d');
my @arraytwo = ('c','d','a','b'); 

my $arrays_match_result=match_arrays(\@arrayone,\@arraytwo);

if($arrays_match_result==1) {
    print "Array's contain the same element value's.\n";
}else{
    print "Array's do not contain the same element value's.\n";
}

sub match_arrays {
    my ($array1,$array2)=@_;
    my @array1_matches;
    my @array2_matches;
    my $matches=0;
    # Return 0 straight away, 
    # if respective array lengths are not equal
    unless ($#$array1==$#$array2) {
          return 0;
    }
    for(my $mc1=0;$mc1<=$#$array1;$mc1++) {
        for(my $mc2=0;$mc2<=$#$array2;$mc2++) {
            # If the elements match. Eliminate the
            # respective matched elements 
            # cross out the box's with the same contents)
            # and don't worry about them again.
            if(@$array1[$mc1] eq @$array2[$mc2]&&$array2_matches[$mc2]
+!=1&&$array1_matches[$mc1]!=1) {
                $array2_matches[$mc2]=1;
                $array1_matches[$mc1]=1;
                $matches++;
                print "Match[$matches] -> Array1 : Element: $mc1 (@$ar
+ray1[$mc1]) matched Array2 : Element: $mc2 (@$array2[$mc2])\n";
            }
        }
    }
    if($matches==$#$array1+1) {
        return 1;
    }else{
        return 0;
    }
}
