Computer Science 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 Apti · 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 = N-M+1N-M+1
