title: Separate characters and numbers from a string
body: <p>I have a string variable that contain character and numbers like this </p>
  
  <pre><code>var sampleString = "aaa1211"
  </code></pre>
  
  <p>Note that variable always start with a <code>character/s</code> and end with <code>number/s</code>. Character and number size is not fixed. It could be something like followings </p>
  
  <pre><code>var sampleString = "aaaaa12111"
  var sampleString = "aaa12111"
  </code></pre>
  
  <p>I need to separate the characters and numbers and assign them into separate variables.</p>
  
  <p>How could I do that ? </p>
  
  <p>I try to use split and substring but for this scenario I couldn't apply those. I know this is a basic question but i'm search over the internet and I was unable to find an answer. </p>
  
  <p>Thank you</p>
