UVA-111854 - Egypt

 

 

Problem A: Egypt

A long time ago, the Egyptians figured out that a triangle with sides of length 3, 4, and 5 had a right angle as its largest angle. You must determine if other triangles have a similar property.

The Input

Input represents several test cases, followed by a line containing 0 0 0. Each test case has three positive integers, less than 30,000, denoting the lengths of the sides of a triangle.

The Output

For each test case, a line containing "right" if the triangle is a right triangle, and a line containing "wrong" if the triangle is not a right triangle.

Sample Input

6 8 10
25 52 60
5 12 13
0 0 0

Output for Sample Input

right
wrong
right

 



#include<stdio.h>
int main()
{
    int a,b,c,H1,H2,H3;
    while(scanf("%d%d%d",&a,&b,&c)==3)
    {
        if((a==0)&&(b==0)&&(c==0))
           {
               break;
           }
        H1=(a*a+b*b);
        H2=(a*a+c*c);
        H3=(b*b+c*c);
 
        if((c*c)==H1)
    printf("right\n");
        else if((b*b)==H2)
    printf("right\n");
 
        else if((a*a)==H3)
    printf("right\n");
    else
    {
      printf("wrong\n");
    }
    }
 return 0;
}
