Description

Write a program that reads a positive integer.

• If the integer is a multiple of 3 but not a multiple of 5, output 1.

• If the integer is a multiple of 5 but not a multiple of 3, output 1.

• In all other cases, output 0.

For example:

• If the input is 36 or 20, the output should be 1.

• If the input is 30 or 7, the output should be 0.

Input

A positive integer

Output

The result of the rules.

If the input is 36 or 20, the output should be 1.

If the input is 30 or 7, the output should be 0.

Description

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.

Input

three positive integers a, b, and c

Output

If it is an acute triangle, output 1.

If it is an obtuse triangle, output 2.

If it is a right triangle, output 3.
