RANGE QUERY

Given a (big) array r[0..n-1], and a lot of queries of certain type. We may want to pre-process the data so that each
query can be performed fast. In this section, we use T (f, g) to denote the running time for an algorithm is O(f(n)) 
for pre-processing, and O(g(n)) for each query.

If the queries are of type getsum(a, b), which asks the sum of all the elements between a and b, inclusive, 
we have a T (n, 1) algorithm: Compute s[i] to be the sum from r[0] to r[i-1], inclusive, then getsum(a,b) simply 
returns s[b+1]-s[a].
