yes, I know that. However, the problem we are facing is that while we are not printing anything, the checker is telling us that our answer is wrong because of a newline character in the output line of the prewritten code.

    // Print the result of 3 calls to Adder's `add(int,int)` method as 3 space-separated integers:
    System.out.print(a.add(10,32) + " " + a.add(10,3) + " " + a.add(10,10) + "\n");
