body: <p>What is the best we can do with run length encoding. </p>
  
  <p><a href="http://en.wikipedia.org/wiki/Run-length_encoding" rel="nofollow noreferrer">This page</a> suggests the time complexity is O(m*n) where m is the number of time the number repeats.. </p>
  
  <p>Is the a more efficient algorithm to do RLE?</p>
