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

This is the solution that made the most sense to me as a ruby beginner

def reverse(string)
  reversed_string = ''

  i = 0
  while i < string.length
    reversed_string = string[i] + reversed_string
    i += 1
  end

  reversed_string
end

p reverse("helter skelter")
