Hello Monks
i have one subroutine which will take input the range of numbers and gives the expansion of it.
to be clear , if i input 2-8,10-13,18 it will give 2,3,4,5,6,7,8,10,11,12,13,18 which iam going to use it in my array extraction..
subroutine is as below(just framed as one example)... 
#!/usr/bin/perl

print "To get the range of numbers \n";
print "Enter the range to see expansion \n";
chomp($range=<STDIN>);
print "The range from subroutine is :",join("==>",&get_numbers_from_ra
+nges($range)),"\n";


sub get_numbers_from_ranges {
    my $spec = shift;

    my %numbers;
    foreach my $x ( split ',', $spec ) {
        $x =~ s/\s*//g;
        if ( $x =~ /(\d+)-(\d+)/ ) {
            $numbers{$_} = undef for $1 .. $2;
        }
        else {
            $numbers{$x} = undef;
        }
    }
    # subtracting every element by one because these are used in array
+s i.e. 1st element in array index is 0
    #return map { $_ - 1 } sort { $a <=> $b } keys %numbers;
    return map { $_ - 1 } keys %numbers;
}

my problem is , i dont want the result to be sorted , i want the result unsorted .
for instance, if i give input as 6-9,1-3,11 i need output as 6,7,8,9,1,2,3,11 , but iam not able to achieve this, by using sort iam getting 1,2,3,6,7,8,9,11 which is not iam looking for.
if i remove sort statement as see above in code, iam getting wrong output
pls help me to fix the above code where i get the expansion of numbers in the order i inputted..
