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) = Eio* Ap+i · Aq+i-
M-1
i=0
You should process Q queries. In each query:
• You are given two integers pos and val. Change the value of Apos to val.
N-M+1N-M+1
• Then, find the sum S = E
E;-1 F(i, j). Since this sum could
be very large, compute it modulo 998, 244, 353.
