Obfuscation 关于混淆的问题

Problem Description
It is a well-known fact that if you mix up the letters of a word, while leaving the first and last letters in their places, words still remain readable. For example, the sentence “tihs snetncee mkaes prfecet sesne”, makes perfect sense to most people.

If you remove all spaces from a sentence, it still remains perfectly readable, see for example: “thissentencemakesperfectsense”, however if you combine these two things, first shuffling, then removing spaces, things get hard. The following sentence is harder to decipher: “tihssnetnceemkaesprfecetsesne”.

You’re given a sentence in the last form, together with a dictionary of valid words and are asked to decipher the text.

Input
On the first line one positive number: the number of testcases, at most 100. After that per testcase:

One line with a string s: the sentence to decipher. The sentence consists of lowercase letters and has a length of at least 1 and at most 1 000 characters.

One line with an integer n with 1 ≤ n ≤ 10 000: the number of words in the dictionary.

n lines with one word each. A word consists of lowercase letters and has a length of at least 1 and at most 100 characters. All the words are unique.

Output
Per testcase:

One line with the deciphered sentence, if it is possible to uniquely decipher it. Otherwise “impossible” or “ambiguous”, depending on which is the case.

Sample Input
3
tihssnetnceemkaesprfecetsesne
5
makes
perfect
sense
sentence
this
hitehre
2
there
hello
hitehre
3
hi

three

Sample Output
this sentence makes perfect sense
impossible
ambiguous
