Easy

This problem is very easy. As my mood is not so good, I will not elaborate the statement unnecessarily. In this problem you will be given N sets. Each of them will contain some distinct integer numbers. You have to form a new set using some chosen sets from given sets in a way such that there is no common element among the chosen sets and the number of total elements in the newly formed set is the maximum possible.
