Problem: The evil mastermind, Moriarty, strikes again!  He sent Sherlock an image of a wall, with N integers painted on it. Sherlock is asked to solve the puzzle and find the next clue.
Sherlock knows that Moriarty is a deceitful person. All the numbers painted on the wall are not valid. Only the numbers that are Coprime with the integer X are valid, and the rest are a deceit. Help Sherlock find the valid integers from the given array A so that he can track down Moriarty.  

Input:
First line contains T. T test cases follow.
First line of each test case contains two space-separated integers N and X.
Second line of each test case contains N space-separated integers, forming the array A. 

Output:
Print the valid integers separated by spaces in the order that they appear in the list or "-1" (without the quotes) if there are no valid integers, in a new line for each test case.  

Constraints:
1 ≤ T ≤ 10
1 ≤ N ≤ 10^4
2 ≤ Ai, X ≤ 10^7

SAMPLE INPUT
1
5 4
2 5 8 3 13

SAMPLE OUTPUT
5 3 13

Solution (in PYTHON):

Solution:
def gcd(a, b):
    if b == 0:
        return a
    else:
        return gcd(b, pow(a, 1, b))

T = int(raw_input())
for i in range(T):
    _, X = map(int, raw_input().split())
    As = map(int, raw_input().split())
    co_filter = make_coprime_filter(X)
    r = filter(co_filter, As)
