You are given two vectors in the form of
vector $\vec{A} = a_1i+a_2j+a_3k$ and $\vec{B} = b_1i+b_2j+b_3k$
where $a_1, a_2, a_3,b_1, b_2, b_3$ are integers.
and $i$, $j$, $k$ are dimensions of the given vector.

You have to find the vector product $\vec{A}\times \vec{B}$
It is guaranteed that all three dimensions are given.

Input

First line contain number of test cases $t$

Each test case contain 2 lines denoting vector $\vec{A}$ and vector $\vec{B}$respectively.

Output

Print a single line for each test case consist of vector product in the form $\vec{C} = c_1i+c_2j+c_3k$

Constraints

$1 <= t <= 10^5$

$-10^6 <= a_1,a_2,a_3,b_1,b_2,b_3 <= 10^6$
