title: Comparing two listBuffer in Scala
body: <p>I have a class like :</p>
  <pre><code>case class (a: String, b: String, c: ListBuffer)
  </code></pre>
  <p>I have multiple object of this class.<br>
  I want output class in such way that if two object have similar <strong>listbuffer</strong> element in that, then it should add in result only once (duplicate should be avoided).</p>
