CF133A.HQ9+

HQ9+ is a joke programming language which has only four one-character instructions:

• "H" prints "Hello, World!",
• "Q" prints the source code of the program itself,
• "9" prints the lyrics of "99 Bottles of Beer" song,
• "+" increments the value stored in the internal accumulator.

Instructions "H" and "Q" are case-sensitive and must be uppercase. The characters of the program which are not instructions are ignored.

You are given a program written in HQ9+. You have to figure out whether executing this program will produce any output.

HQ9+ 是一种玩笑性质的编程语言，仅包含四条单字符指令：

• “H” 输出 “Hello, World!”；
• “Q” 输出该程序自身的源代码；
• “9” 输出歌曲《99 Bottles of Beer》的歌词；
• “+” 对内部累加器中存储的值加 1。

指令 “H” 和 “Q” 区分大小写，必须为大写字母。程序中所有非指令的字符均被忽略。

现给出一段用 HQ9+ 编写的程序，请判断执行该程序是否会生成任何输出。

The input will consist of a single line p which will give a program in HQ9+. String p will contain between 1 and 100 characters, inclusive. ASCII-code of each character of p will be between 33 (exclamation mark) and 126 (tilde), inclusive.

输入将仅包含一行字符串 $p$，表示一个 HQ9+ 程序。字符串 $p$ 的长度为 $1$ 到 $100$ 个字符（含端点）。$p$ 中每个字符的 ASCII 码值均在 $33$（感叹号 !）到 $126$（波浪号 ~）之间（含端点）。

Output "YES", if executing the program will produce any output, and "NO" otherwise.

如果执行该程序会产生任何输出，则输出 “YES”，否则输出 “NO”。

In the first case the program contains only one instruction — "H", which prints "Hello, World!".

In the second case none of the program characters are language instructions.

在第一种情况下，程序仅包含一条指令——“H”，它会输出“Hello, World!”。

在第二种情况下，程序中的字符均不是该语言的指令。
