body: <p>Say I have a list of countries </p>
  
  <pre><code>l = ['India', 'China', 'China', 'Japan', 'USA', 'India', 'USA']  
  </code></pre>
  
  <p>and then I have a list of unique countries </p>
  
  <pre><code>ul = ['India', 'China', 'Japan', 'USA']
  </code></pre>
  
  <p>I want to have a count of each unique country in the list in ascending order. So output should be as follows:</p>
  
  <pre><code>Japan 1
  China 2
  India 2
  USA   2
  </code></pre>
