How to sort a string's characters alphabetically?

Assuming there is a simple string str = "bacd" I want to sort it so that the result contains result = "abcd"

How do I do this in Ruby?

Answer 1

Tokland's comment is so nice it deserves to be a full-fledged answer:

str.chars.sort.join

This works in Ruby 1.8 and 1.9.

You can find the Ruby Doc here.

Answer 2

Nice and simple:

str = 'bacd'
p str.split('').sort.join # => "abcd"
