title: Select numbers from array which are much greater than the rest
body: <p>Say there is an array of n elements, and out of n elements there be some numbers which are much bigger than the rest. </p>
  
  <p>So, I might have: </p>
  
  <pre><code>16, 1, 1, 0, 5, 0, 32, 6, 54, 1, 2, 5, 3
  </code></pre>
  
  <p>In this case, I'd be interested in <code>32</code>, <code>16</code> and <code>54</code>.</p>
  
  <p>Or, I might have: </p>
  
  <pre><code>32, 105, 26, 5, 1, 82, 906, 58, 22, 88, 967, 1024, 1055 
  </code></pre>
  
  <p>In this case, I'd be interested in <code>1024</code>, <code>906</code>, <code>967</code> and <code>1055</code>.</p>
  
  <p>I'm trying to write a function to extract the numbers of interest. The problem is that I can't define a threshold to determine what's "much greater", and I can't just tell it to get the <code>x</code> biggest numbers because both of these will vary depending on what the function is called against.</p>
  
  <p>I'm a little stuck. Does anyone have any ideas how to attack this?</p>
