Reverse Function

I'm trying to have the function FirstReverse(flip) take the flip parameter being passed and return the string in reversed order.

Here's what I have so far:

def FirstReverse(flip)

  flip = flip.reverse
  return flip

end

Hi Daniel,

Is this from a code challenge?

What problem are you having?

Your code seems to do what you want it to do.

Oh ok gotcha, this was something I was running offline. Wasn't sure if it was correct.

Couple of comments about your code Daniel Hunter

  • Method names should start with a lowercase letter; it'll work as you have it but isn't idiomatic ruby.
  • You wouldn't need the return call here as ruby methods always return the value of the last evaluated statement.
  • Likewise the assignment isn't needed either as flip.reverse would be evaluated and returned.

Putting those notes together a more idiomatic ruby version of this method would look like this:

  def first_reverse(flip)
    flip.reverse
  end
