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

43 4 52 2 3 1 4 44 6 3

 

Sample Output

goodperfectperfectjust a triangle

题目分析

判断三角形的类型，并按给定要求输出，直角三角形输出good，等腰三角形输出perfect,其他三角形输出just a triangle

解题思路

水题，判断一下就行
