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)

process.stdin.resume();
process.stdin.setEncoding('utf8');
var lines = [];
var w;
var count= 0;
var reader = require('readline').createInterface({
  input: process.stdin,
  output: process.stdout
});
reader.on('line', (line) => {
  lines.push(line);
});
reader.on('close', () => {
  var x = lines[0];
  for(var i = 0; i<x.length;i++){
     w =  x.slice(i,i+1);
     count = count + parseInt(w[0]);
  }
  if(count % 9 == 0){
    console.log('Yes');
  }else if (count % 9 != 0){
    console.log('No');
  }
  console.log(lines[0]);
});
