A polynomial in x
of degree D can be written as:
aDxD + aD-1xD-1 + ... + a1x1 + a0
In some cases, a polynomial of degree **D**
can also be written as the
product of two polynomials of degrees **D1**
and **D2**
, where **D = D1 \+ D2**
. For instance,
4 x2 + 11 x 1 + 6 = (4 x1 + 3) * (1 x1 + 2)
In this problem, you will be given two polynomials, denoted **F**
and
**G**
. Your task is to find a polynomial **H**
such that **G** * **H** = **F**
, and each ai
is an integer.
Input
You should first read an integer **N ≤ 60**
, the number of test cases. Each
test case will start by describing **F**
and then describe **G**
. Each
polynomial will start with its degree 0 ≤ **D** ≤ 20
, which will be followed
by **D**+1
integers, denoting a0, a1, ... , aD
, where -10000 ≤ ai ≤ 10000
. Each polynomial will have a non-zero coefficient for it's highest
order term.
Output
For each test case, output a single line describing **H**
. If **H**
has
degree **DH**
, you should output a line containing **DH** \+ 1
integers,
starting with a0
for **H**
. If no **H**
exists such that **G*H=F**
,
you should output "no solution".
