title: Count words without LOOPS
body: <p>I have a question about Ruby:</p>
  
  <p>Given an input string, I need to return a hash, whose keys are words in the string and whose values are the number of times each word appears. IMPORTANT: I must not use for-loops. </p>
  
  <p>Example: "Today is a day, a sunrise"
  Output: {'Today'=>1, 'is'=>1, 'a'=>2, 'day' =>1, 'sunrise'=>1}</p>
  
  <p>Can you help me?</p>
