- Chương trình trả về giá trị 0 nếu AC, 1 nếu WA. Những thông tin được viết ra stdout (bằng cout) sẽ được in ra màn hình cho người nộp bài(feedback) + Chương trình trả về giá trị: +
Chương trình sau dùng để chấm bài toán: Cho n là một số nguyên dương. In ra hai số tự nhiên a, b sao cho a + b = n.
+Nếu in ra a + b = n và a, b >= 0 thì được 100% số điểm, nếu a + b = n nhưng một trong 2 số a, b âm thì được 50% số điểm.
