Problem Statement

An integer N is a multiple of 9 if and only if the sum of the digits in the decimal representation of N is a multiple of 9.

Determine whether N is a multiple of 9.

Constraints

0 \leq N < 10^{200000}

N is an integer.

Input

Input is given from Standard Input in the following format:

N

Output

If N is a multiple of 9, print Yes; otherwise, print No.

Sample Input 1

123456789

Sample Output 1

Yes

The sum of these digits is 1+2+3+4+5+6+7+8+9=45, which is a multiple of 9, so 123456789 is a multiple of 9.

Sample Input 2

0

Sample Output 2

Yes

Sample Input 3

31415926535897932384626433832795028841971693993751058209749445923078164062862089986280

Sample Output 3

No

use proconio::*;
use proconio::marker::*;

fn run() {
    input! {
        s: Bytes,
    }
    let mut sum = 0;
    for c in s {
        sum += (c - b'0') as usize;
    }
    let ans = if sum % 9 == 0 {
        "Yes"
    } else {
        "No"
    };
    println!("{}", ans);
}

fn main() {
    run();
