There are several test cases, process to EOF, about 20 test cases.
For each test case, one line contains eight real numbers x1,y1,x2,y2,x3,y3,x,y.
Orz pandas are at points (x1,y1),(x2,y2),(x3,y3);
The person are at point (x,y)
Every coordinate is bigger than -1001 and smaller than 1001.
For each test case, output one line.If the person is in the triangle(include at the edge), output"Orz".Otherwise output"stO"(without quotation marks).
