不必多写，可以写一起

#include<bits/stdc++.h>
using namespace std;
char b;
int main(){
	cin>>b;
	if((int)b%2)cout<<"YES";
	else cout<<"NO";
	return 0;
}

#include <bits/stdc++.h>
using namespace std;
int main(){
	char a;
	cin>>a;
	int b=a;
	if(a%2==0) cout<<"NO";
	else cout<<"YES";
	return 0;
}

#include<bits/stdc++.h> 
using namespace std;

const int maxn = 114514;

int main(){
	char a;
	cin >> a;
	int b;
	b = (int)a;
//	cout << b;
	if (b % 2){
		cout << "YES";
		
	}
	else cout << "NO";
	return 0;
}
