**Note: The only difference between this chapter and [chapter 1](https://www.facebook.com/codingcompetitions/hacker-cup/2022/round-1/problems/B1) is that here, coordinates may be up to \(\mathbf{10^9}\).**

Boss Rob just planted \(N\) happy little trees in his yard, which can be represented on a Cartesian plane. The \(i\)th tree is located at coordinates \(t_i = (A_i, B_i)\). Now, he's looking for the best spot to build a well in order to provide water to them. He considers the *inconvenience* of a potential well location \(p\) to be the sum of the squared Euclidean distances to every tree:

\[\sum_{i=1}^{N} \Vert \,p - t_i \Vert ^ 2 \]

Rob wants to pick a location for his well, well... well. Help him determine the inconvenience for \(Q\) different potential well locations, \((X_1, Y_1), ..., (X_Q, Y_Q)\). To reduce output size, please print the sum of inconveniences for all potential well locations, modulo \(1{,}000{,}000{,}007\).


# Constraints

\(1 \le T \le 50\)
\(1 \le N, Q \le 500{,}000\)
\(0 \le A_i, B_i, X_i, Y_i \le \mathbf{10^9}\)
All \((A_i, B_i)\) are distinct within a given test case.
All \((X_i, Y_i)\) are distinct within a given test case.

The total sum of \(N\) and \(Q\) across all test cases is at most \(3{,}000{,}000\).


# Input Format

Input begins with a single integer \(T\), the number of test cases. For each case, there is first a line containing a single integer \(N\). Then, \(N\) lines follow, the \(i\)th of which contains two space-separated integers \(A_i\) and \(B_i\). Then there is a line containing a single integer \(Q\). Then, \(Q\) lines follow, the \(i\)th of which contains two space-separated integers \(X_i\) and \(Y_i\).


# Output Format

For the \(i\)th test case, print a line containing `"Case #i: "`, followed by a single integer, the sum of inconveniences for all \(Q\) well locations, modulo \(1{,}000{,}000{,}007\).


# Sample Explanation

The first two sample cases are depicted below:

{{PHOTO_ID:3620154144878669|WIDTH:700}}

In the first case, the total inconvenience is \(18 + 34 = 52\):

- For the well at \((2, 5)\), the inconvenience is the sum of the squared Euclidean distance to both trees, which is \(3^2 + 3^2 = 18\).
- For the well at \((6, 6)\), the inconvenience is \(32 + 2 = 34\).

In the second case, the total inconvenience is \(47 + 31 + 53 = 131\):

- For the well at \((3, 1)\), the inconvenience is \(4 + 5 + 13 + 25 = 47\).
- For the well at \((5, 2)\), the inconvenience is \(17 + 2 + 2 + 10 = 31\).
- For the well at \((6, 5)\), the inconvenience is \(41 + 8 + 4 + 0 = 53\).
