title: removing last element of a list(scheme)
body: <p>So I have to remove the last element of a list in scheme.</p>
  
  <p>For example, let's say I have a list <code>(1 2 3 4)</code>. I need to return:</p>
  
  <pre><code>(1 2 3)
  </code></pre>
  
  <p>My idea:</p>
  
  <pre><code>reverse(list)
  car(list)
  reverse(list)
  </code></pre>
  
  <p>Is there a <code>reverse</code> function in scheme(racket)?</p>
