#include <iostream>
using namespace std;

int main() {
    // Step 1: Read the input character
    char ch;
    cin >> ch;

    // Step 2: Check if the ASCII value of the character is odd
    bool isOdd = (ch % 2) != 0; // Here, we use the modulo operator to check for oddness

    // Step 3: Output the result based on the oddness check
    if (isOdd) {
        cout << "YES";
    } else {
        cout << "NO";
    }

    return 0;
