There are n users registered on a website CuteKittens.com. Each of them has a unique password represented by pass[1], pass[2], ..., pass[N]. As this a very lovely site, many people want to access those awesomely cute pics of the kittens. But the adamant admin does not want the site to be available to the general public, so only those people who have passwords can access it.

Yu, being an awesome hacker finds a loophole in the password verification system. A string which is a concatenation of one or more passwords, in any order, is also accepted by the password verification system. Any password can appear $\mbox{0}$ or more times in that string. Given access to each of the $n$ passwords, and also have a string $log in Atempt$, determine whether this string be accepted by the password verification system of the website.  If all of the $log in Atempt$ string can be created by concatenating password strings, it is accepted.  In this case, return the passwords in the order they must be concatenated, each separated by a single space on one line.  If the password attempt will not be accepted, return 'WRONG PWASSWORD'.

Examples 

$passwords=[\text{'abra'},\:\:\text{'ka'},\:\:\text{'dabra'}]$ 

$log inAtempt=\textbf{'abrakadabra'}$   

Concatenate the passwords in index order $0,1,2$ to match 'abrakadabra'. Return 'abra ka dabra'.  

$passwords=[\text{'abra'},\:\:\text{'ka'},\:\:\text{'dabra'}]$ 

$log in Atempt=\text{'kaabra'}$   

Concatenate the passwords in index order $\mathbf{1},\mathbf{0}$ to match 'kaabra'. Return 'ka abra'.  

$passwords=\textbf{['ab'},\:\:\textbf{'ba']}$ 

$log in Atempt=\textbf{'aba'}$   

Concatenate the passwords in index order $\mathbf{0,1}$ to match 'abba', $\mathbf{1},\mathbf{0}$ to match 'baab', $\boldsymbol{0},\boldsymbol{0}$ to match 'abab' or $\boldsymbol{1,1}$ to match $baba'.  No combination of 1 or more passwords can be concatenated to match 'aba'.  Return 'WRONG PASSWORD'.   

Function Description

Complete the passwordCracker function in the editor below.   

passwordCracker has the following parameters: 

- string passwords[n]: a list of password strings 

- string loginAttempt: the string to attempt to create  

Returns 

- string: Return the passwords as a single string in the order required for the password to be accepted, each separated by a space. If it is not possible to form the string, return the string WRONG PASSWORD.  

Input Format

The first line contains an integer t, the total number of test cases.  

Each of the next $\boldsymbol{\boldsymbol{t}}$ sets of three lines is as follows: 

- The first line of each test case contains n, the number of users with passwords. 

- The second line contains n space-separated strings, passwords[i], that represent  the passwords of each user. 

- The third line contains a string, loginAttempt, which Yu must test for acceptance.  

Constraints

$1\leq t\leq10$  
$1\leq n\leq10$  
$passwords[i]\neq passwords[j],1\leq i<j\leq N$  
$1\leq|passwords[i]|\leq10$, where $i\in[1,n]$  
$1<|loginAtempt|\leq2000$ 
loginAttempt and passwords[i] contain only lowercase latin characters ('a'-'z').

ab abcd cd
abcd

Sample Output 0
we do what we must because we can
WRONG PASSWORD
ab cd

Explanation 0

Sample Case #00: "wedowhatwemustbecausewecan" is the concatenation of passwords {"we", "do", "what", "we", "must", "because", "we", "can"}. That is 

loginAttempt = pass[5] + pass[3] + pass[6] + pass[5] +  pass[4] + pass[1] + pass[5] + pass[2]

Note that any password can repeat any number of times.  

Sample Case #01: We can't create string "helloworld" using the strings {"hello", "planet"}.  

Sample Case #02: There are two ways to create loginAttempt ("abcd"). Both pass[2] = "abcd" and pass[1] + pass[3] = "ab cd" are valid answers.
