题目描述

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.

输入格式

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

输出格式

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