  static boolean sort(int[] n){
    int temp;
    Arrays.sort(n);
    int[] s = {5,5,7};
    Arrays.sort(s);
    if(Arrays.equals(n,s)){
      return true;
    }
    return false;
  }

    Scanner sc = new Scanner(System.in);
    int[] n = new int[3];
    for(int i = 0;i<3;i++){
      n[i] = sc.nextInt();
    }
    if(sort(n)){
      System.out.println("YES");
