Description

Captain Marmot wants to prepare a huge and important battle against his enemy, Captain Snake. For this battle he had N Regiments, each consisting of 4 moles.

Initially, each mole i (1?≤? I? ≤?4N) is placed at some position (xi,? Yi) 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 I T ' s possible.

Input

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

The Next 4 n  lines Contain 4  integers  x i ,   y i ,   a i ,   b i   (?-? 104?≤? X i ,? Y i ,? A i ,? b i ? ≤?104 ).

Output

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 R Equired moves. Otherwise, on the i-th line Print "-1" (without quotes).

Sample Input

Input
41 1 0 0-1 1 0 0-1 1 0 01-1 0 01 1 0 0-2 1 0 0-1 1 0 01-1 0 01 1 0 0-1 1 0 0-1 1 0 0-1 1 0 02 2 0 1-1 0 0-23 0 0-2-1 1 -2 0
Output
1-133

Hint

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.
