title: String matching algorithm
body: <p>Say I have 3 strings. And then 1 more string.<br>
  Is there an algorithm that would allow me to find which one of the first 3 strings matches the 4th string the most?<br>
  None of the strings are going to be exact matches, I'm just trying to find the closest match.<br>
  And if the algorithm already exists in STL, that would be nice.</p>
  
  <p>Thanks in advance.</p>
