It is not the best way to directly translate from other languages to Ruby. One of the 
interesting features of Ruby is the use of enumerators and blocks wherever possible, hence you will rarely need for loop in Ruby program.

You don't need for loop to go over each character in the string. This snippet will
print each char of the string:

"my test string".chars {|c| puts c}

There is my somewhat obscure implementation (needs Ruby 1.9 because of .rotate):
