Given a number of petals, return a string which repeats the phrases Loves me and Loves me not for every alternating petal, and return the last phrase in all caps.

Remember to put a comma and space between phrases.

Solution

This is the answer I came up with:

def loves_me(num)
  result = []
  last = num - 1
     
  num.times { |time|
    if time.even?
      result << "Loves me"
    else
      result << "Loves me not"
    end
    }
  
  result[last] = result[last].upcase
  return result.join(", ")
end
