title: Changes between two hashes in ruby
body: <p>I have two hashes with the below format</p>
  
  <pre><code>mydetails[x['Id']] = x['Amount']
  </code></pre>
  
  <p>this would contain data like</p>
  
  <pre><code>hash1 = {"A"=&gt;"0", "B"=&gt;"1","C"=&gt;"0", "F"=&gt;"1"}
  hash2 = {"A"=&gt;"0", "B"=&gt;"3","C"=&gt;"0", "E"=&gt;"1"}
  </code></pre>
  
  <p>I am expecting an output something like:</p>
  
  <blockquote>
    <p>Differences in hash: "B, F, E"</p>
  </blockquote>
  
  <p>Any help is very much appreciated.</p>
