title: Ruby how to sort hash of hashes?
body: <p>I have that deep Hash of hashes:</p>
  
  <pre><code>my_hash = { 
      :category_1 =&gt; {
          :solution_1 =&gt; { :order =&gt; 1 },
          :solution_2 =&gt; { :order =&gt; 2 }
      },
      :category_2 =&gt; {
          :solution_3 =&gt; { :order =&gt; 3 },
          :solution_4 =&gt; { :order =&gt; 4 }  
      }
  }
  </code></pre>
  
  <p>I want to sort :solution_* hashes under :category_* hashes by key :order. Any suggestions?</p>
