File Merge Operation

You are given T test cases. For each test case, you will be provided with two arrays. The first line of each test case contains two positive integers, N and M, representing the number of elements in the first and second arrays respectively. The next two lines contain N and M integers respectively.

Your task is to merge the two arrays and output the merged array in ascending order. The integers in each output line should be separated by a single space.

Note: The constraints are given as follows: \(1 \leq T \leq 200\), \(1 \leq N, M \leq 100\), and each integer lies in the range \(-1000 \leq x \leq 1000\).

inputFormat

The input is read from stdin and has the following format:

T
N1 M1
a1 a2 ... aN1
b1 b2 ... bM1
N2 M2
... (and so on for T test cases)

Where T is the number of test cases, and for each test case, N and M are provided followed by two lines containing the respective arrays.

outputFormat

For each test case, output a single line on stdout containing the merged and sorted array. The numbers should be separated by a single space.
