title: Pop the back of a queue without using a deque
body: <p>Is it possible to pop the back of a queue in C++ without using a deque? How would this be done? </p>
  
  <pre><code>queue&lt;int&gt; myQ;
  
  myQ.pop(back());
  </code></pre>
  
  <p>I know this doesn't work, but hopefully it gives an idea of what I'm trying to do. </p>
