CF133A HQ9+
Description
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.
Input Format
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.
Output Format
Output "YES", if executing the program will produce any output, and "NO" otherwise.
Explanation/Hint
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.
