Python Programming Problem: You are given a sequence of integers A1, A2, ..., AN and an integer M. For any valid integers p, q, let's define F(p, q) as the dot product of the subsequences Ap, Ap+1, . .. , Ap+M-1 and Aq, Aq+1,..., Aq+M-1, İ.e. F(p, q) = Eo Ap+ti ' Aq+i- %3D You should process Q queries. In each query: • You are given two integers pos and val. Change the value of Apos to val. • Then, find the sum S = N-M+1N-M+1 F(i,j). Since this sum could Lj-1 be very large, compute it modulo 998, 244, 353. Test Case Result 310 64 271 25
