Bài 5. Trò chơi oản tù tì                                                                  tên file: GAMES.***

Hai bạn Bắc và Nam chơi trò chơi oản tù tì, trong quá trình chơi mỗi người chơi sẽ đưa ra một trong ba hình dạng của bàn tay là: búa, kéo và bao. Trong đó luật chơi được mô tả như sau:

·        Người chơi ra hình búa sẽ thắng người chơi ra hình kéo.

·        Người chơi ra hình kéo sẽ thắng người chơi ra hình bao.

·        Người chơi ra hình bao sẽ thắng người chơi ra hình búa.

Hai người chơi ra hình giống nhau thì sẽ hòa.

Tại một lượt chơi, hai bạn Bắc và Nam sẽ đưa ra một hình dạng bàn tay của mình. Em hãy lập trình cho biết kết quả ai là người thắng, hoặc hai bạn hòa nhau.

INPUT:

Gồm hai số nguyên a và b (0 ≤ a, b ≤ 2). Trong đó 0 nếu đó là búa, 1 nếu đó là kéo, 2 nếu đó là bao

Số a là ký hiệu hình bàn tay của bạn Bắc, số b là ký hiệu hình bàn tay của bạn Nam

OUTPUT:

·        Nếu bạn Bắc thắng thì đưa ra từ “BAC”.

·        Nếu bạn Nam thắng thì đưa ra từ “NAM”.

·        Nếu hai bạn hòa nhau thì đưa ra từ “HOA”.

·        Chú ý kết quả đưa ra là chữ in hoa.

Bài 4. Số chính phương                                                                  tên file: chinhphuong.***

Số chính phương là một số nguyên dương bằng bình phương của một số nguyên dương. Ví dụ: 1, 4, 9, 16, 100 … là những số chính phương; còn 3, 8, 15 … không phải là những số chính phương.

Cho trước một số nguyên dương n. Em hãy kiểm tra xem n có phải là số chính phương không?

Input: Một dòng duy nhất chứa số nguyên dương n.

Output: Đưa ra thông báo "yes" nếu n là số chính phương, ngược lại thông báo "no".

Ví dụ:

Viết chương trình nhập vào từ bàn phím số nguyên N( 0<n<10000).

Kiểm tra xem số đó có chia hết cho 2 và cho 3 không, hay số đó không chia hết cho cả 2 và 3, hoặc chia hết cho 2  nhưng không chia hết cho 3 hay ngược lại không chia hết cho 3 nhưng không chia hết cho 2.
