CF7C.Line

A line on the plane is described by an equation Ax + By + C = 0. You are to find any point on this line, whose coordinates are integer numbers from  - 5·1018 to 5·1018 inclusive, or to find out that such points do not exist.

平面上的一条直线由方程 $Ax + By + C = 0$ 描述。你需要找出该直线上任意一个坐标均为整数的点，且其横纵坐标均在 $[-5 \cdot 10^{18},\, 5 \cdot 10^{18}]$ 范围内（含端点）；若不存在这样的点，则需判定并报告不存在。

The first line contains three integers A, B and C ( - 2·109 ≤ A, B, C ≤ 2·109) — corresponding coefficients of the line equation. It is guaranteed that _A_2 + _B_2 > 0.

第一行包含三个整数 $A$、$B$ 和 $C$（$-2\cdot10^9 \le A,\,B,\,C \le 2\cdot10^9$），分别对应直线方程的系数。保证 $A^2 + B^2 > 0$。

If the required point exists, output its coordinates, otherwise output -1.

如果所求的点存在，输出其坐标；否则输出 $-1$。
