Problem Statement

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 Rust (1.15.1) (judge verdict: Accepted)

fn main(){
    let mut input = "".to_string();
    std::io::stdin().read_line(&mut input).ok();
    let splitted = input.trim().split_whitespace().map(|c| {let i:usize = c.parse().unwrap(); i} ).collect::<Vec<usize>>();
    let count7 = splitted.iter().fold(0, |mut acc, x| {
     if *x == 7usize { acc += 1; }   
     acc });
    let count5 = splitted.iter().fold(0, |mut acc, x| {
     if *x == 5usize { acc += 1; }   
     acc });
    if count7 == 1 && count5 == 2 {
        println!("{}", "YES");
    } else {
        println!("{}", "NO");
    }
}
