hdu 4156-egypt-计算几何-[解题报告]hoj

Problem Description
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.

 

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.
 

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
 

Sample Output
right wrong right

        break;
        sort(a,a+3);
        if(a[0]*a[0] + a[1]*a[1] == a[2]*a[2])
        cout << "right" << endl;
        else
        cout << "wrong" << endl;
    }

    return 0;
