HDU3188:Just A Triangle

Problem Description
This is an easy problem, just for you to warm up.

Give you three edges of a triangle. Can you tell me which kind of triangle it stands for?

If it’s a right triangle(直角三角形), please output “good”. If it’s a isosceles triangle(等腰三角形), please output “perfect”. Otherwise, please output “just a triangle”. You may suppose the input is legal.



Input
The first line contains an integer t means the number of test cases.

The each case contains three integers a, b, c in a line which stands for the length of the three edges.

(0 <a, b, c < 300).



Output
For each case, output the answer in one line.


Sample Input

4
3 4 5
2 2 3 
1 4 4
4 6 3

Sample Output

good
perfect
perfect
just a triangle
