Hi Guyz,

Problem with me is that whenever i am storing values in my hash… it
stores perfectly …

But when i am trying to print it … i mean try to view its contents …
then contents coming in wrong order … which i dont want …

Can sum one help me bit about it … ?

Hashes won’t keep the insertion order in Ruby (or any other language,
you’ll usually have to use some kind of ordered hash).

Hashes in Ruby 1.9 are ordered by key insertion order.

This isn’t true because the insertion order is maintained in Ruby 1.9.1
as well as Smalltalk.
