Egypt (Editorial)

Let $a, b, c$ a, b, c be the sides of a triangle. A triangle is right-angled if one of the following conditions holds:

$a^{2} = b^{2} + c^{2}$ a^2 = b^2 + c^2 (the hypotenuse is side $a$ )
$b^{2} = a^{2} + c^{2}$ b^2 = a^2 + c^2 (the hypotenuse is side $b$ )
$с^{2} = a^{2} + b^{2}$ с^2 = a^2 + b^2 (the hypotenuse is side $с$ )

Algorithm implementation

Read the input data until the end of the file.

while(scanf("%d %d %d",&a,&b,&c))
{

If three zeros are encountered, terminate the program.

  if (a + b + c == 0) break;

Check whether the triangle is a right triangle. Print the result accordingly.

  if ((a * a + b * b == c * c) ||
      (a * a + c * c == b * b) ||
      (b * b + c * c == a * a))
    puts("right");
  else
    puts("wrong");
}
