title: Deleting the middle element of a list
body: <p>I want to write a Prolog program to delete the middle element from an odd-numbered list into another list.</p>
  <p>For example, If we give : <code>delete_mid([1,2,3,4,5],L)</code> then it will produce : <code>L = [1,2,4,5]</code> as answer.</p>
