Iroha loves Haiku. Haiku is a short form of Japanese poetry. A Haiku consists of three phrases with 5, 7 and 5 syllables, in this order.

To create a Haiku, Iroha has come up with three different phrases. These phrases have A, B and C syllables, respectively. Determine whether she can construct a Haiku by using each of the phrases once, in some order.

Constraints

1≦A,B,C≦10

Input

The input is given from Standard Input in the following format:

A B C

Output

If it is possible to construct a Haiku by using each of the phrases once, print YES (case-sensitive). Otherwise, print NO.

Sample Input 1

5 5 7

Sample Output 1

YES

Using three phrases of length 5, 5 and 7, it is possible to construct a Haiku.

Sample Input 2

7 7 5

Sample Output 2

NO

Solution in Haskell (GHC 7.10.3) (judge verdict: Accepted)

main = putStrLn . format . solve =<< parse

solve :: (Int, Int, Int) -> Bool
solve (5, 5, 7) = True
solve (5, 7, 5) = True
solve (7, 5, 5) = True
solve _ = False

format :: Bool -> String
format True = "YES"
format False = "NO"

parse :: IO (Int, Int, Int)
parse = (\[x, y, z] -> (x, y, z)) . map read . words <$> getLine
