Egypt

/problems/egypt/file/statement/en/img-0001.png

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 (at most $1\, 000$), followed by a line containing 0 0 0. Each test case has three positive integers, at most $30\, 000$, 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.
