# Periodic Function

Statement:

Solar cycle predictions are used by various agencies and many industry groups. The solar cycle is important for determining the lifetime of satellites in low-Earth orbit, as the drag on the satellites correlates with the solar cycle [...]. (NOAA)

The goal of the problem is to propose a perfect prediction center, with not so weak constraints.

Let us consider periodic functions from Z to R.

def f(x): return [4, -6, 7][x%3] # (with Python notations)
# 4, -6, 7, 4, -6, 7, 4, -6, 7, 4, -6, 7, 4, -6, 7, ...

For example, f is a 3-periodic function, with f(0) = f(3) = f(6) = f(9) = 4.
With a simplified notation we will denote f as [4, -6, 7].
For two periodic functions (with integral period), the quotient of periods will be rational, in that case it can be shown that the sum of the functions is also a periodic function. Thus, the set of all such functions is a vector space over R.

For that problem, we consider a function that is the sum of several periodic functions all with as period an integer N at maximum. You will be given some starting values, you'll have to find new ones.

Input:

On the first line, you will be given an integer N.
On the second line, you will be given integers y : the first (0-indexed) N×N values of a periodic function f that is sum of periodic functions all with as period an integer N at maximum.
On the third line, you will be given N×N integers x.

Output:

Print f(x) for all required x. See sample for details.

Example input:
3
15 3 17 2 16 4 15 3 17
10 100 1000 10000 100000 1000000 10000000 100000000 1000000000

Example output:
16 16 16 16 16 16 16 16 16

Explanation:

For example f can be seen as the sum of three periodic functions : [10] + [5, -8] + [0, 1, 2] (with simplified notations ; periods are 1,2 and 3)
In that case f(10) = [10][10%1] + [5, -8][10%2] + [0, 1, 2][10%3] = 10 + 5 + 1 = 16, and so on.

Constraints:

N < 258
abs(y) < 109
0 <= x < 109

Informations:

You can safely assume output fit in a signed 32bit container. There's 6 input files, with increasing value of N. Some details (#i, N) :

• (#0, around 50)
• (#1, around 50)
• (#2, around 100)
• (#3, around 150)
• (#4, around 200)
• (#5, around 250)

Time and memory limit:

• 3s
• 256MB
