Solve without using arrays
<p>I have 9 questions for my assignment, all of them are fine except one question. I don't need a full answer, please give some <strong>hints</strong> or tell me how to do this <em>without using any arrays</em>.</p>

<blockquote>
  <p>A robot is created in a 4x4 room containing a number of stacks of
  beepers. The room is always the  same size. </p>
  
  <p>One of the stacks will always contain more beepers than any of the
  others. </p>
  
  <p>In Q8 write a  method called <code>findBiggestStack()</code> that directs the most
  recently created robot to identify the largest  stack of beepers
  present. </p>
  
  <p>Say that the stack at (3, 2) is the biggest stack, and contains 7
  beepers,  then the method should print.</p>
  
  <p>The biggest stack is at (3, 2) and contains 7 beepers</p>
