  <p>While I got to understand the <code>insert</code> of the <code>2-3 tree</code> and  the <code>LLRB</code>, I have spent totally like 40 hours now for 2 weeks and I still can't get the deletion of the LLRB.</p>
  
  <p>Can anyone really explain the <code>deletion</code> of <code>LLRB</code> to me?</p>
