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 |

不用考虑不能构成三角形的情况，所以连判断是不是三角形的条件都不用加。所以简单了。下面上代码。
#include <stdio.h>
#include <string.h>
int main()
{
int n,i;
scanf("%d",&n);
while(n--)
{
int a,b,c;
scanf("%d%d%d",&a,&b,&c);
if(a*a==b*b+c*c ||b*b==a*a+c*c || c*c==a*a+b*b)
printf("good\n");
else if(a==b ||b==c ||a==c )
printf("perfect\n");
else
printf("just a triangle\n");
}
return 0;
} |
