Given some integers, please list them in increasing order.
First line is an integer T (T <= 20) followed by T test cases. For each test case, start with an integer n (n <= 106) and follow by n integers V1, V2, ..., Vn. ( Vi < 231 for 1 <= i <= n )
For each test case, list numbers from the smallest one to the largest one in one line. Two adjacent numbers in one line should be separated by a whitespace.
