단어 사다리란 퍼즐의 한 종류인데, 두 단어가 주어지면 한 단어에서 한 글자씩 바꿔서 다른 단어를 만드는 것이다. 이 게임은 좋은 어휘력과 맞춤법이 필요하다. 그래서 정답인지 아닌지 확인하는 게 너무 지루하고 귀찮다. 

한 쌍의 단어가 단어 사다리가 되는 조건은 다음과 같다:

  • 단어의 길이가 같고
  • 반드시 한 글자씩 바뀌어야한다.

단어 사다리가 가능한 지 판별하는 프로그램을 작성하시오.

입력

입력이 여러 번 주어지는데, #이 입력되기 전까지를 하나의 테스트케이스로 간주한다.

각 테스트케이스는 3자 이상 20자 이하의 대문자 알파벳으로 된 단어들이 순서대로 입력된다. 입력의 마지막 줄에는 #이 주어진다.

출력

단어 사다리가 가능하다면 'Correct'를, 아니면 'Incorrect'를 출력한다.
