title: How to split and remove empty spaces before get the result
body: <p>I have this <code>String</code>:</p>
  
  <pre><code>val str = "9617 / 20634"
  </code></pre>
  
  <p>So after split i want to parse only the 2 values <code>9617 &amp; 20634</code> in order to calculate percentage.
  So instead of <code>trim</code> after the split can i do it before ?</p>
