You are given a list of M positive numbers, Ao. A1, .... AM-1- You have to answer Q queries. Each query has four parameters, I, r, n, k. Given a query with parameters I, r, n, k here is how to compute the answer: • Let (B1, B2 . Ba) = (Aj, A+1. .. A,), where d = r-l+1. • Let S= set of all points (x1, X2, Xa) in d-dimensional space such that 0 < x; .... SBj. For x, y eS, define dist(x, y) = min, sisal X - Yil • The answer is number of subsets of S of size exactly n such that distance (denoted by above defined dist function) between any two points is at least k.
