題目描述

 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.

 

輸入

 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.

輸出

 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.

示例輸入

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

示例輸出

#include<stdio.h>
void main()
{
 int a,b,c,temp;
 while(scanf("%d %d %d",&a,&b,&c),a||b||c)//abc同時wei0的時候結束
 {
  if(a>b)
  {
   temp=a;
   a=b;
   b=temp;
  }
  if(a>c)
  {
   temp=a;
   a=c;
   c=temp;
  }
  if(b>c)
  {
   temp=b;
   b=c;
   c=temp;
  }
  if(a*a+b*b==c*c)
   printf("right\n");
  else
   printf("wrong\n");

 }
