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

use std::io::Read;

fn main() {
    let mut buf = String::new();
    std::io::stdin().read_to_string(&mut buf).unwrap();

    // 条件を同じにするため一度Vecに貯める
    let v = buf.split_whitespace()
        .map(|x| x.parse::<u32>().unwrap())
        .collect::<Vec<_>>();
  
  
  	let mut result = "NO";
    let mut count5 = 0;
  	let mut count7 = 0;

  	for x in v.into_iter() {
  		if x == 5 {
          count5 += 1;
        }
        if x == 7 {
          count7 += 1;
        }
      
        if count7 == 1 && count5 == 2 {
          result = "YES"
        }
  	}

    println!("{}", result);
}
