Solution in Rust (1.42.0) (judge verdict: Accepted)

use proconio::input;
fn main() {
    input! {
        a: usize,
        b: usize,
        c: usize
    }
    let A = [a, b, c];
    let test1 = [7, 5, 5];
    let test2 = [5, 7, 5];
    let test3 = [5, 5, 7];
    if A == test1 {
        println!("YES");
    } else if A == test2 {
        println!("YES");
    } else if A == test3 {
        println!("YES");
    } else {
        println!("NO");
    }
