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
题目大意
给你三个数,如果可以组成直角三角形,就输出good,如果可以组成等腰三角形,就输出perfect,如果不符合这两种情况就输出just a triangle。
额外收获
1、判断是否可以组成三角形:
两边之和大于第三边&&两边之差小于第三边
2、warm up 热身
代码
