Skip Letter Code

Time Limit: 10 Seconds      Memory Limit: 32768 KB

Romeo and Juliet are college students in the city of Verona and are in love with each other. Unfortunately, both their families are not very glad with this fact. They are trying to prevent any attempts of young people to communicate. Thus, Romeo and Juliet had to introduce their special code to be capable of writing love letters to each other. Both of them have a little book of Shakespeare sonnets and agreed to use this book as a dictionary for their code. The code is like follows: only words that appear in the dictionary may be used in the love letter. Then, the person who writes the letter may skip some letters in each word. Of course that person tries to skip as may letters as possible, but he would keep in mind that the letter should be decoded with just one possibility for each word. Oh, such a difficult task! Fortunately, both of the lovers have a personal computer and you can (can't you?) help them writing the program, that being given with the dictionary and the coded message decodes one if there is just one way to decode the message or reports that there could be more than one decoding possibility. Thus, you will help both writing and reading persons.

This problem contains multiple test cases!

The first line of a multiple input is an integer N, then a blank line followed by N input blocks. Each input block is in the format indicated in the problem description. There is a blank line between input blocks.

The output format consists of N output blocks. There is a blank line between output blocks.

Input

First line of the input contains single integer 1 <= N <= 100 - number of words in a dictionary. Next N lines each contain one word from the dictionary. Each word in a dictionary is not longer than 5 characters and (as well as coded message) consists from capital letters A to Z. The rest of file (up to # character) contains coded message (no longer than 10^6 characters) which is coded words separated by space(s) and/or newline characters.

Output

Output should contain single line with word AMBIGUITY if there could be more than one possible decoding of the message or decoded message with all spaces and newline characters kept intact. Note, that # character should not be printed.
