题目描述

Practice does make perfect! You have finally achieved proficiency at the task of adding two small nonzero integers $a$ and $b$ to compute their sum $a+b$. Before you move on to studying four-digit numbers, you want to achieve mastery by also understanding the inverse problem: given integer $s$, determine nonzero $a$ and $b$ such that $a+b=s$. None of the numbers may use more than $3$ digits.

输入格式

The input consists of:

• One line with an integer $s$ such that $-999\leq s\leq 999$.

输出格式

Output two integers $a$ (with $-999\leq a\leq 999$ and $a\neq 0$) and $b$ (with $-999\leq b\leq 999$ and $b\neq 0$) such that $a+b=s$. If there is more than one valid solution, you may output any one of them.

Explanation of Sample Input 1

On input $\texttt{10}$, the output $\texttt{3 7}$ is correct because $3+7=10$. Note that many other outputs would also be correct, such as $\texttt{2 8}$, $\texttt{11 -1}$, or even $\texttt{-849 859}$. On the other hand, the answer $\texttt{4 7}$ would be $\emph{wrong}$ (because $4+7\neq 10$), and so would $\texttt{10 0}$ (because both $a$ and $b$ must be nonzero) and $\texttt{1000 -990}$ (because both $a$ and $b$ must have at most three digits.)
