title: Finding the number of odd/even values in a dictionary
body: <p>I have a dictionary, let's it key value pair be as follow:</p>
  
  <pre><code>a - 1
  b - 3
  c - 2
  </code></pre>
  
  <p>I want to find out the number of odd and even value chars. For example, the above will return me 2 odd and 1 even.</p>
  
  <p>I was thinking of iterating but I read iterating is the wrong way if we are using a dictionary. What is the best approach?</p>
