Problem type

Mirko decided to open a new business – bank vaults. A branch of the bank can be visualized in a plane, vaults being points in the plane. Mirko's branch contains exactly L\cdot (A+1+B) vaults, so that each point with integer coordinates inside the rectangle with corners (1, -A) and (L, B) contains one vault.

The vaults are watched by two guards – one at (0, -A), the other at (0, B). A guard can see a vault if there are no other vaults on the line segment connecting them.

A vault is not secure if neither guard can see it, secure if only one guard can see it and super-secure if both guards can see it.

Given A, B and L, output the number of insecure, secure and super-secure vaults.

Input Specification

The first line contains integers A and B separated by a space (1 \le A, B \le 2000). The second line contains the integer L (1 \le L \le 1\,000\,000\,000).

Output Specification

Output on three separate lines the numbers of insecure, secure and super-secure vaults.

Scoring

In test cases worth 50\% of points, L will be at most 1000.

In test cases worth another 25\% of points, A and B will be at most 100 (but L can be as large as one billion).
