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 Go (1.14.1) (judge verdict: Accepted)

package main

import "fmt"

var N string

func main() {
  fmt.Scanf("%s", &N)
  res := 0
  for i := range N {
    res += int(N[i]) - 48
    res %= 9
  }
  if res%9 == 0 {
    fmt.Println("Yes")
    return
  }
  fmt.Println("No")
}
