Write a program that reads three positive integers a, b, and c, and determines whether the triangle with side lengths a, b, and c is an acute triangle, an obtuse triangle, or a right triangle.
If it is an acute triangle, output 1.
If it is an obtuse triangle, output 2.
If it is a right triangle, output 3.
You may assume that the input values a, b, and c can always form a valid triangle.

If it is an acute triangle, output 1.
If it is an obtuse triangle, output 2.
If it is a right triangle, output 3.
