Why this conflict?. Please clear my doubt. I actually expect

To get this output what I need to do Mail me as early as possible
Well that's the way hashes work. If you have a recent version of Perl, at
least the order will be the same.
However to do what you want, you could use the Tie::IxHash module
use Tie::IxHash;
.....
tie %Items, "Tie::IxHash";
See the Perl Cookbook, Ch 5.6
See perldoc Tie::IxHash
(Tie::IxHash - ordered associative arrays for Perl)
