Chef recently learned about mex work and came up with a similar job. In the (possibly empty) series of positive S numbers, Chef defines uf (S) as the smallest positive number that does not appear in S. For example, f ([) = 1, f ([3,4,3, 5]) = 1, f ([2,5,1,1,2,3]) = 4. Chef's friend heard from Chef's idea and found it really cool. So, he sent a sequence a1, a2, N, and to the Chef and asked him to get the sum of f (S) over all possible next 2N of this series. As Chef is busy, he has entrusted you with problem solving. As the resulting amount can be very large, we have included module 998,244,353

Question
![Code in C++:
Chef recently learned about mex work and came up with a similar job. In the (possibly empty) series
of positive S numbers, Chef defines uf (S) as the smallest positive number that does not appear in S.
For example, f ([]) = 1, f ([3,4,3, 5]) = 1, f ([2,5,1,1,2,3]) = 4.
Chef's friend heard from Chef's idea and found it really cool. So, he sent a sequence a1, a2, N, and to
the Chef and asked him to get the sum of f (S) over all possible next 2N of this series. As Chef is busy,
he has entrusted you with problem solving.
As the resulting amount can be very large, we have included module 998,244,353
