Question

I am trying to write a little Ruby program that can insert two letters behind consonants only within a string. I’m trying to do it using two classes within a main class by passing the characters of a string to the block associated with the class method. One method would insert the letters, the other would be able to remove them.

Here’s what I have so far:

class Mytranslator
  def to_mytrans( string )
    letters = string.inject( 'it' ) {|letters, char| collection += char}
    puts letters
  end


  def to_normaltrans( string )

  end
end

Problem is, I don’t know if I’m even on the right track. And I have no idea how to write the second method. Any help would be greatly appreciated. Thanks.

Answer 1

def to_mytrans(s)
  s.gsub(/([^aeiouAEIOU])/,'\1it')
end

def to_normaltrans(s)
  s.gsub(/([^aeiouAEIOU])it/,'\1')
end

This will fail if your string has numbers/punctuation etc.
