Description
 
Given two integer sequences A and B,you are to find A-B,the difference of them, (i.e.,the elements that are in A but not in B),and ouput them in increasing order.Equal elements should be treated as the same.
Input
Input consists of multiple test cases.The first line of input contains a positive integer T,the number of test cases.Each test case consists of two lines.The first line begins with an integer N,followed by N integers for the sequence A.The second line begins with an integer M,followed by M integers for B.0<=N,M<=1000,and all the integers are within the scope of the type int.
 
Output
For each test case,output on a single line the difference of the two sequeces in increasing order.
