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

Solution in JavaScript (Node.js 12.16.1) (judge verdict: Wrong Answer)

/**
 * 
 * @param {String} input 
 */
function Main(input) {
//    const [n, x, t] = input.split(" ").map(v => parseInt(v, 10));
    const n = input;

    let sum = 0
    
    for (let index = 0; index < n.length; index++) {
        const v = n.charAt(index);
        sum += parseInt(v, 10);
    }
	//出力
	console.log(sum % 9 === 0 ? 'YES': 'NO');
}
