本文介绍了一种方法来判断HQ9+程序是否会生成输出。通过检查特定指令字符，可以快速确定程序是否包含会产生输出的操作。

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

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

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

Sample test(s)

Input

Hi!

Output

YES

Input

Codeforces

Output

NO

很长时间没做了，熟悉的感觉，判断字符串中的字符的存在

#include <algorithm>
#include <iostream>
#include <cstdio>
#include <cstring>
using namespace std;
int main()
{
	string s;
	int flag;
	while(cin>>s)
	{
		flag=0;
		for(int i=0;i<s.size();i++)
		{
			if(s[i]=='H'||s[i]=='Q'||s[i]=='9')
			{
				flag=1;
				break;
			}
		}
		if(flag)
			puts("YES");
		else
			puts("NO");
	}
	return 0;
}
