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;
