The timing must be strictly adhered to.
Judgement of organizers is final.
In the independent session the three participants are not allowed to communicate with each other. They can pass on any vital information in the form of code comments.
Team of three is compulsory for the finals - no more, no less. In the prelims exceptions can be made for a team size of less than three in case of clashing events etc. Upon qualification if the team fails to participate in full strength in the finals, the team will be removed from selection and the next best deserving team will be given a chance to participate in the finals.
The only eligibility of a successful submission in the finals is the correctness of output as decided by the OJ.
