Reverse a string in Ruby

Question

How do you reverse a string in Ruby? I know about string#reverse. I\'m interested in understanding how to write it in pure Ruby, preferably an in-place solution.

Answer 1

I believe this would work also

def reverse(str)
  string = ''
   (0..str.size-1).each do |i|
    string << str[str.size - 1 - i]
   end
  string
end
