As we can see the first cell holds only the first value in the array, the second cell hold the sum of the first two values and the third cell holds the first three values and so on... Back to the sum query we can now calculate any query in O(1) using this array. For example:...
Define F(B), B is a subarray (consecutive) of array A, is the number of distinct values of B. For example: F({1, 2, 3, 4}) = 4 For every query i x, change value A[i] to x, and calculate the sum of all F(B) in the new array A. For a query when A = {1, 1, ...

We need to compute a prefix sum of the Dirichlet convolution (f∗g)(n)(f∗g)(n). In this article, we will consider some general methods, and show how to do so in O(n2/3)O(n2/3) if we can compute prefix sums of F(n)F(n) and G(n)G(n) in all possible values of ...
Okay then, what are the values of such function? I don't really know, but Wikipedia says that ζ(−k)=(−1)kBk+1k+1.ζ(−k)=(−1)kBk+1k+1. Well, that's nice to know! We have no idea about Bernoulli numbers, or any other properties of Riemann zeta functions ζ(s)ζ...
