C+ Programming Question: 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, 9) 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) = M- M-1 =o° Ap+i · Aqti- 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 =5N-M+1¬N-M+1 F(i,j). Since this sum could Zuj-1 be very large, compute it modulo 998, 244, 353. si=1 Test Case Result 340 521 32415 24

C+ Programming Question: 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+i · Aqti- M-1 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 = 5N-M+1¬N-M+1 F(i, j). Since this sum could Lj-1 be very large, compute it modulo 998, 244, 353. Test Case Result 1 340 521 32415 24
