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 tri- angle 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 13 000 Sample Output right wrong right
