public void solve(int testNumber, InputReader in, OutputWriter out) {
        int a1 = in.nextInt();
        int b1 = in.nextInt();
        int a2 = in.nextInt();
        int b2 = in.nextInt();
        int a3 = in.nextInt();
        int b3 = in.nextInt();

        out.println((a1 - a3) + " " + (b1 - b2));
    }
