#write me a function stringy that takes a size and returns a string of alternating '1s' and '0s'.
#the string should start with a 1.
#a string with size 6 should return :'101010'.
#with size 4 should return : '1010'.
#with size 12 should return : '101010101010'.
#The size will always be positive and will only use whole numbers.


#My Solution:

#Create a function with two arguments that will return a list of length (n) with multiples of (x).
#Assume both the given number and the number of times to count will be positive numbers greater than 0.
#Return the results as an array (or list in Python, Haskell or Elixir).
#Examples:
#count_by(1,10) should return [1,2,3,4,5,6,7,8,9,10]
#count_by(2,5) should return [2,4,6,8,10]

#My Solution:

def count_by(x, n)

#Jenny has written a function that returns a greeting for a user. However, she's in love with Johnny, and would 
#like to greet him slightly different. She added a special case to her function, but she made a mistake.
#Can you help her?

#Initial Code with Error:

def greet(name)
  return "Hello, #{name}!"
  return "Hello, my love!" if name == "Johnny"
