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. Note: 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.
