Captain Marmot wants to prepare a huge and important battle against his enemy, Captain Snake. For this battle he has $*n*$ regiments, each consisting of $4$ moles.

翻译中…

Initially, each mole $*i*$ ($1 ≤ *i* ≤ 4*n*$) is placed at some position $(*x*_{*i*}, *y*_{*i*})$ in the Cartesian plane. Captain Marmot wants to move some moles to make the regiments compact, if it's possible.

翻译中…

Each mole $*i*$ has a home placed at the position $(*a*_{*i*}, *b*_{*i*})$. Moving this mole one time means rotating his position point $(*x*_{*i*}, *y*_{*i*})$ $90$ degrees counter-clockwise around it's home point $(*a*_{*i*}, *b*_{*i*})$.

翻译中…

A regiment is compact only if the position points of the $4$ moles form a square with non-zero area.

翻译中…

Help Captain Marmot to find out for each regiment the minimal number of moves required to make that regiment compact, if it's possible.

Input

翻译中…

The first line contains one integer $*n*$ ($1 ≤ *n* ≤ 100$), the number of regiments.

翻译中…

The next $4*n*$ lines contain $4$ integers $*x*_{*i*}$, $*y*_{*i*}$, $*a*_{*i*}$, $*b*_{*i*}$ ($- 10^{4} ≤ *x*_{*i*}, *y*_{*i*}, *a*_{*i*}, *b*_{*i*} ≤ 10^{4}$).

Output

翻译中…

Print $*n*$ lines to the standard output. If the regiment $*i*$ can be made compact, the $*i*$-th line should contain one integer, the minimal number of required moves. Otherwise, on the $*i*$-th line print "-1" (without quotes).

翻译中…

Note

翻译中…

In the first regiment we can move once the second or the third mole.

翻译中…

We can't make the second regiment compact.

翻译中…

In the third regiment, from the last $3$ moles we can move once one and twice another one.

翻译中…

In the fourth regiment, we can move twice the first mole and once the third mole.
