Problem Description

This is a magic country
Harmonious society
And harmonious people

This is a wonderful contest
Harmonious students
And harmonious problems.

This is the most harmonious problem, and the question is as following:
Given three positive integers A, B and C (0<A,B,C<=100) which denote the length of three edges, please tell me whether they can make up a legal triangle.

Input

The first line is an integer T(T<=100) which indicates the number of test cases.
Each test case consists of three integers A,B and C in a line.

Output

For each test case please output the type of triangle (Acute triangle、Right triangle or Obtuse triangle) if  A,B and C can make up a legal triangle, and output "NO" otherwise. 
One line per case.

Sample Input

4
3 4 4
3 4 5
3 4 6
3 4 7

Sample Output

Acute triangle
Right triangle
Obtuse triangle
NO
