body: <p>How to print the output on the same line by overwriting the previously printed Timing(countdown) value?</p>
  <p>As shown below, after each second, the timing value is printed on the next row.</p>
  <pre class="lang-none prettyprint-override"><code>13:35:01
  
  13:35:00
  
  13:34:59
  
  13:34:58
  
  13:34:57
  
  13:34:56
  </code></pre>
  <p>I want the timing value to be printed on the same row clearing the previous one.</p>
