Print arrays in Perl
===

I am using Perl in Ubuntu. I have assigned few values to an array and when I am printing the array it is giving some HASH values. 

Can anybody assist me with this?

Here is the code.
        `#!/usr/bin/perl
        my $VAR="you are welcome";
        my @arr={'1','2','3','4'};
        print @arr;
        print $VAR."\n";
        print "$$ \n";`


Here is the output 

    HASH(0x140cd80)you are welcome 
    12548
