title: Text comparison algorithm
body: <p>We have a requirement in the project that we have to compare two texts (update1, update2) and come up with an algorithm to define how many words and how many sentences have changed.</p>
  
  <p>Are there any algorithms that I can use?</p>
  
  <p>I am not even looking for code. If I know the algorithm, I can code it in Java.</p>
