Background

초기 문명을 이해하기 위해, 고고학자들은 고대 문자로 쓰여진 글들을 자주 연구한다. 3000년 이상 전에 이집트에서 사용되었던 문자들은 물체들의 형태를 본 따 만든 상형문자이다. 아래 그림은 6개의 상형문자와 그 이름이다.



6개의 문자를 판독하는 프로그램을 만들어보자.

Input

상형문자가 포함되어있는 여러 개의 그림 데이터가 순서대로 입력된다.
각 그림 데이터의 첫 번째 줄에는 줄의 개수(H)와 각 줄에 있는 16진수 표현 개수(W)가 공백을 두고 입력된다.
그 다음 H개의 줄에는 위부터 아래까지 각 줄의 이미지를 표현하는 16진수 표현이 입력된다.
그림이 더 이상 없는 경우에는 H W 대신 0 0이 입력된다.

입력되는 각 그림 데이터는 아래 조건을 만족한다:
- 6개의 상형문자만 사용된다.
- 적어도 1개 이상의 상형문자가 포함되어있다.
- 검정 픽셀은 반드시 어떤 상형문자의 일부이다.
- 상형문자는 검정 픽셀들이 연결되어 만들어지며, 검정 픽셀은 위/아래/왼쪽/오른쪽 중 1개 이상의 다른 검정 픽셀이 연결되어있다.
- 상형문자는 서로 겹쳐지거나 그 안에 다른 상형문자를 포함하고 있지 않다.
- 대각선으로 있는 검은 픽셀은 반드시 공통적으로 연결되어있는 다른 픽셀이 있다.
- 문자는 기울어져 있을 수 있지만, (그래프) 위상으로는 반드시 6개 문자 중 하나와 같다.

[입력값의 정의역]

$0 < H <= 200$
$0 < W <= 50$

Output

케이스별로 케이스 번호를 출력하고, 각 이미지에서 분석된 상형문자들을 아래와 같은 알파벳 오름차순으로 순서대로 출력한다.:

Ankh: A
Wedjat: J
