This is the most harmonious problem, and the question is as following:

[align=left]Input[/align]
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.
[align=left]Output[/align]
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.
