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.
