本题原本格式如下：

You are given two positive integers uu and vv , find any pair of integers (not necessarily positive) xx , yy , such that: $\frac{x}{u} + \frac{y}{v} = \frac{x + y}{u + v}. </li><li> The solution x = 0x=0 , y = 0y=0 is forbidden, so you should find any solution with (x, y) \\neq (0, 0)(x,y) neq(0,0)$.

我进行了更改，版本如下：

You are given two positive integers $u$ and $v$ , find any pair of integers (not necessarily positive) $x$, $y$, such that: $\frac{x}{u} + \frac{y}{v} = \frac{x + y}{u + v}.$ The solution $x = 0$ , $y = 0$ is forbidden, so you should find any solution with (x, y) which is not both $0$

这里提供一个源码：

麻烦各位管理员帮忙修改一下，谢谢。
