1380：Triangles

 This is a simple problem. Given two triangles A and B, you should determine they are intersect, contain or disjoint. (Public edge or point are treated as intersect.)

 First line contains an integer T (1 ≤ T ≤ 10), represents there are T test cases.
For each test case: X1 Y1 X2 Y2 X3 Y3 X4 Y4 X5 Y5 X6 Y6. All the coordinate are integer. (X1,Y1) , (X2,Y2), (X3,Y3) forms triangles A ; (X4,Y4) , (X5,Y5), (X6,Y6) forms triangles B.
-10000<=All the coordinate <=10000

 For each test case, output “intersect”, “contain” or “disjoint”.
