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 Haskell (GHC 8.8.3) (judge verdict: Accepted)

solve :: [Char] -> Int -> String
solve a b
 | null a    = if (b `mod` 9) == 0 then "Yes" else "No"
 | otherwise = solve (tail a) (b + aInt)
   where aInt = (fromEnum (head a)) - 48

main = do
 a <- getLine :: IO [Char]
 putStr $ solve a 0
