body: <p>I have a table value like below,</p>
  
  <pre><code>id tank_id filledTime
  1   TIND10 6PM,7PM,9PM,9PM,7PM,11PM,7PM,9PM,7PM,7PM,8PM,7PM,10PM,8PM,7PM,8PM,8PM,6PM,8PM,9PM,8PM,11PM,8PM
  </code></pre>
  
  <p>Expecting output :</p>
  
  <pre><code>tank_id NoOfTimeFilledInSpecTime
  TIND10  2(6PM),7(7PM),4(9PM),2(11PM),7(8PM),1(10PM)
