title: Bubble sort and selection sort
body: <p>I would just like to know the key differences between these two sorting methods because they are very similar and have got me confused.</p>
  
  <p>For example, if I had a sorted array:</p>
  
  <pre><code>x = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15]
  </code></pre>
  
  <p>What would be some differences in the number of comparisons and movements between using selection and bubble sort on this sorted list.</p>
