Netaji Subhas Institute of Technology(NSIT) is one of the best engineering colleges in India. But the attendance rules are very strict there.

Now it's time for Moksha which is one of the biggest fests in North India. But Prof. Dena is taking his class and all the students have very low attendance (They would be detained!). But they also want to go to the fest. So as a surprise, Prof. Dena is giving free attendance to all the student (Yes he is very kind). But there is a condition - "All the students will get attendance if half or more than half of the class is present".

So some of the kind hearted students are ready to attend the class so that the other students could attend the fest.

Now you have to tell if they are going to be detained or not.
