evaluate an expression following BODMAS rules
Sigiloso
Theme of Hackathon varies every week. Mine is a coding challenge of expression evaluation. And it was about 2 hrs. Also I came to know that they may ask you to develop a game or web/android application. And its instructions would be different. They only consider the approach you followed, not the completion. I am pretty sure, if you have 4 yeras or below they can reject you for no reason even though u perform well.
