문제

여기 구글에서, 최고의 언어인 구글語스를 소개합니다. 구글語스로 번역하기 위해, 저희들은 메시지의 각 영문자를 다른 영문자로 변환합니다. 이 변환은 일대일이고, 독립적인데, 그 말은 한 가지의 영문자는 항상 동일한 영문자로 변환되며, 서로 다른 영문자는 항상 다른 결과를 출력하게 됩니다. 이 때 영문자는 변환 후에도 그대로일 수도 있으며, 공백(' ')은 항상 그대로 남게 됩니다.

예(라고 쓰는 단서)를 들면, 저희의 멋진 변환 알고리즘은 다음과 같은 변환 기능을 포함하고 있습니다:  'a' -> 'y', 'o' -> 'e', 그리고 'z' -> 'q'입니다. 이 말은 "a zoo"라는 문자열을 "y qee"로 변환하는 것을 의미합니다.

구글語스는 항상 최고의 변환 규칙을 가지고 있으며, 이 규칙은 항상 똑같습니다. 저희는 규칙을 바꿀 생각 또한 없습니다. 각각의 테스트 케이스에 대해서, 저희는 모든 변환 규칙을 보여주지 않을 생각입니다. 하지만 아래의 몇 가지 예시가 도움이 될 수도 있겠군요.

만약 구글語스로 되어 있는 문자열이 주어지면, 해석할 수 있나요?

입력

입력의 첫 번째 줄에는 테스트 케이스의 개수 T가 주어진다.

각 테스트 케이스는 한 줄의 문자열 G로 이루어지는데, 이 문자열은 'a'부터 'z'로 구성되어 있으며, 문자열의 시작과 끝에는 띄어쓰기(' ')가 없으며, 단어들 사이에는 단 한 개의 공백(' ')이 주어진다.

조건

  • 1 ≤ T ≤ 30.
  • 문자열 G는 최대 100개의 글자로 이루어져 있다.
  • 어떤 문자열도 일반적인 영어로 해석된다는 보장은 없다.

출력

각 테스트케이스에 대해 "Case #X: S"라는 형식에 맞추어 출력한다.

이 때, X는 테스트케이스 순서이며, S는 문자열 G를 해석한 것이다.

To translate text into Googlerese, we take any message and replace each English letter with another English letter.

A letter may be replaced by itself.
