103430: [Atcoder]ABC343 A - Wrong Answer

Problem Statement

You are given two integers $A$ and $B$, each between $0$ and $9$, inclusive.

Print any integer between $0$ and $9$, inclusive, that is not equal to $A + B$.

Constraints

• $0 \leq A \leq 9$
• $0 \leq B \leq 9$
• $A + B \leq 9$
• $A$ and $B$ are integers.

Input

The input is given from Standard Input in the following format:

$A$ $B$

Output

Print any integer between $0$ and $9$, inclusive, that is not equal to $A + B$.

Sample Input 1

2 5

Sample Output 1

2

When $A = 2, B = 5$, we have $A + B = 7$. Thus, printing any of $0, 1, 2, 3, 4, 5, 6, 8, 9$ is correct.

问题描述

给你两个整数$A$和$B$，每个都在$0$到$9$之间，包括$0$和$9$。

打印一个在$0$到$9$之间的整数，不等于$A + B$。

限制条件

• $0 \leq A \leq 9$
• $0 \leq B \leq 9$
• $A + B \leq 9$
• $A$和$B$都是整数。

输入

输入从标准输入以以下格式给出：

$A$ $B$

输出

打印一个在$0$到$9$之间的整数，不等于$A + B$。

当$A = 2, B = 5$时，我们有$A + B = 7$。因此，打印$0, 1, 2, 3, 4, 5, 6, 8, 9$中的任意一个都是正确的。
