Problem Statement

AtCoDeer has three cards, one red, one green and one blue.

An integer between 1 and 9 (inclusive) is written on each card: r on the red card, g on the green card and b on the blue card.

We will arrange the cards in the order red, green and blue from left to right, and read them as a three-digit integer.

Is this integer a multiple of 4?

Constraints

1 ≤ r, g, b ≤ 9

Input

Input is given from Standard Input in the following format:

r g b

Output

If the three-digit integer is a multiple of 4, print YES (case-sensitive); otherwise, print NO.

Sample Input 1

4 3 2

Sample Output 1

YES

432 is a multiple of 4, and thus YES should be printed.

Sample Input 2

2 3 4

Sample Output 2

NO

234 is not a multiple of 4, and thus NO should be printed.

use std::io::*;

struct Stdio {
    sin : Stdin,
    sout : Stdout,
    buf : Vec<String>,
    len : usize,
    cnt : usize,
}

impl Stdio {
    fn new() -> Stdio  {
        Stdio {
            len : 0,
            cnt : 0,
            sin : stdin(),
            sout : stdout(),
            buf : Vec::new(),
        }
    }
    
    fn read_line(&mut self) {
        let mut s = String::new();
        let mut loc = self.sin.lock();
        loc.read_line(&mut s).unwrap();
        self.buf = s.trim().split_whitespace().map(|s| s.to_string()).collect();
        self.len = self.buf.len();
        self.cnt = 0;
    }

    fn read_i32(&mut self) -> i32 {
        if self.len == self.cnt {
            self.read_line();
        }
        let ret = self.buf[self.cnt].parse::<i32>().ok().unwrap();
        self.cnt += 1;
        ret
    }

    fn read_string(&mut self) -> String {
        if self.len == self.cnt {
            self.read_line();
        }
        let ret = self.buf[self.cnt].clone();
        self.cnt += 1;
        ret
    }
    fn write(&mut self , s : &str) {
        write!(self.sout ,"{}" ,s).unwrap();
    }
}

fn main() {
    let mut stdio = Stdio::new();
    let r = stdio.read_string();
    let g = stdio.read_string();
    let b = stdio.read_string();
    let rgb = r + &g + &b;
    let rgb :i32 = rgb.parse().unwrap();
    if rgb % 4 == 0 {
        stdio.write("YES");
    } else {
        stdio.write("NO");
