题目描述
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.
Initially, each mole $i$ ( $1<=i<=4n$ ) 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.
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 $(a_{i},b_{i})$ .
A regiment is compact only if the position points of the $4$ moles form a square with non-zero area.
Help Captain Marmot to find out for each regiment the minimal number of moves required to make that regiment compact, if it's possible.

输出格式
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).

In the first regiment we can move once the second or the third mole.
We can't make the second regiment compact.
In the third regiment, from the last $3$ moles we can move once one and twice another one.
In the fourth regiment, we can move twice the first mole and once the third mole.
We can't make the second regiment compact.
In the third regiment, from the last $3$ moles we can move once one and twice another one.
In the fourth regiment, we can move twice the first mole and once the third mole.
