Good work Tharaka, I really enjoyed it. I saw guys around me trying to solve it too, and it was more of who finishes first rather than how to finish and get tickets. The question here is around the motive. If you want the excitement of solving a puzzle you’ll do it by yourself. If you are doing it to get something (tickets, marks, etc…), that’s when people try to do it by hook or by crook. Nevertheless, salute for the effort put it!
