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 params: Vec<i32> = read_vec_i32();
    println!("{}", solve(params));
}

fn solve(mut param: Vec<i32>) -> String {
    param.sort();
    return if param == [5, 5, 7] {
        String::from("YES")
    } else {
        String::from("NO")
    };
}

fn read_vec_i32<T: std::str::FromStr>() -> Vec<T> {
    let mut line = String::new();
    std::io::stdin().read_line(&mut line).unwrap();
    line.trim()
        .split_whitespace()
        .map(|s| s.parse().ok().unwrap())
        .collect()
}
