Plasmatic is having a test on the different types of triangles! However, he is unable to answer any questions because he was playing videogames in online classes. He vaguely remembers that the teacher taught ~3~ types of triangles -- acute, right and obtuse, but he doesn't remember how to identify any of them. He doesn't want to fail the test, so he needs your help to write a program to solve his problems.

Input Specification

The first line contains ~T~ ~(1 \le T \le 10^5)~, the number of questions.

Each of the following ~T~ lines contains ~l_1, l_2, l_3~ ~(1 \le l_1, l_2, l_3 \le 10^9)~, the side lengths of the triangle. It is guaranteed that the three side lengths forms a valid non-degenerate triangle.

For test worth ~30\%~ of the score, there will be no acute triangles.

Output Specification

For of the ~T~, output A if the triangle formed is acute, R if the triangle formed is right, O if the triangle formed is obtuse.
