수학동아 - 폴리매스
함께 풀고 싶은 문제
창의력을 기를 수 있는 수학 문제 또는 퍼즐을 내는 곳입니다.
어떤 암호기가 있다. 그 암호기는 이름이 피아노-1호다.
피아노-1호는 피아노처럼 보이지만 사실 악보 지지대 부분에 작은 스크린이 있어 그것으로 암호기 기능을 할 수 있다.
피아노-1호에 암호를 입력하면 암호화되어 문장이 나오는데, 이를 피아노-1 암호라고 한다.
다음은 피아노-1 암호의 예시이다. 다음을 보고 밑 문장을 암호화 혹은 해독해주십시오.
주의사항: 피아노-1 암호는 글자 가~사, 알파벳 A~G를 사용합니다. 따라서 G 다음은 A가 오고, 사 다음은 가가 옵니다.
예시) 라마>FG(프그), 가마>CG(크그), 바다>AE(아에) 등
1) '바다 가라'를 암호화하세요.
2) '바나나 사 가라'를 암호화하세요.
3) 'DB BF(드브 브프)'를 해독하세요.
4) 위 암호의 원리를 설명하세요.
힌트는 이 암호 이름이 피아노-1 암호라는 것을 잘 기억해야 합니다.
