I have included a sample OCD configuration, which can be used as a reference to create one. The next step would be to create an interface and an implementation that can help fetch the OSGi configurations.  Interface: Implementation: Let's try to use the OSGi configuration created so far in Models/Servlets. For demonstration purposes, I used AEM Models here, but the same can be implemented in Servlets too. Now that we have created the OSGi configuration. Once building the code, we should be able to see the OSGi configuration in the web console (http://localhost:4502/system/console/configMgr) C...

Input:

The first line of input contains an integer T denoting the number of test cases.
The first line of each test case contains x1, y1, x2, y2, x3, y3, x4, y4 (four points coordinates).

Output:

Print 1  if it is square else 0.

Constraints:

1 ≤ T ≤ 30
1 ≤ x1, x2, x3, x4, y1, y2, y3, y4 ≤ 100

Example:

Input
1
20 10 10 20 20 20 10 10
