title: What is the practical use of the Kadane's algorithm?
body: <p>This algorithm is interesting, I know that it's being used in image processing ( and probably other scenarios ), but what I find strange is that this algorithm also operates on negative values, and negative values are virtually non existent in the imaging world where there are a lot of <code>unsigned int</code> to represent the values .</p>
  
  <p>Could you offer a practical example that takes advantage of the Kadane algorithm ?</p>
