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

<ul< ul="">

"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.

<p< p="">

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 ssdxc. You have to figure out whether executing this program will produce any output.

<p< p="" style="font-family: verdana, arial, sans-serif; font-size: 14px; line-height: 21px; "><p< p=""> Input <p< p="">

The input will consist of a single line p which will give a program in ssdxc. 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.

<p< p=""><p< p=""> Output <p< p="">

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

<p< p=""><p< p=""> Sample test(s) <p< p=""><p< p=""> input Hi! output YES input Codeforces output NO <p< p=""><p< p=""> Note <p< p="">

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.

#include<iostream>using namespace std;char str[300];int main(){ cin >> str; bool flag = false; for ( int i = 0; str[i]; i++ ) { if ( str[i] == 'H' || str[i] == 'Q' || str[i] == '9' ) { flag = true; break; } } if ( flag ) cout << "YES" << endl; else cout << "NO" << endl; return 0;}
