import java.util.stream.IntStream;

public class Main {

	private static final int N = 3;

	public static void main(String[] args) {
		try (Scanner scanner = new Scanner(System.in)) {
			Map<Integer, Integer> map = new HashMap<>();
			IntStream.range(0, N).forEach(i -> {
				int a = scanner.nextInt();
				map.put(a, map.getOrDefault(a, 0) + 1);
			});
			System.out.println(((2 == map.getOrDefault(5, 0)) && (1 == map.getOrDefault(7, 0))) ? "YES" : "NO");
