Given an array arr[] of N numbers. The task is to print only those numbers whose digits are from set {1,2,3}.

Input:
The first line of input contains an integer T denoting the number of test cases. Then T test cases follow. Each test case consists of two lines. First line of each test case contains an integer N and the second line contains N space separated array elements.

Output:
For each test case, In new line print the required elements in increasing order. if there is no such element present in the array print "-1".

Constraints:
1 <= T <= 100
1 <= N <= 10⁶
1 <= A[i] <= 10⁶

Example:
Input:
2
3
4 6 7
4
1 2 3 4

Output:
-1
1 2 3
