title: Find maximum value of minimum elements in tuple
body: <p>If I have a list</p>
  
  <pre><code>[[209, 34], [50, 170], [197, 32], [75, 156], [176, 51], [54, 141], [205, 19], [35, 173]]
  </code></pre>
  
  <p>How would I go about finding the sublist with the maximum minimum element?</p>
  
  <p>ie, in the case above, it would be index<code>[3]</code> - <code>[75,156]</code> because it's minimum value is greater than the minimum value of all other elements. </p>
