package Assignment;

import java.util.Scanner;
public class Largestnofromgivenarray {

public static void main(String[] args) {
       Scanner sc = new Scanner (System.in);
	   int tc=sc.nextInt();
	   int[] arr= null;
	   String ab ="";
	   String ba="";
	   String ans =""; 
	   for(int row=1;row<=tc;row++) {
		   int nv=sc.nextInt();
		   arr =new int[nv];
		   for(int col=0;col<nv;col++) {
			   arr[col]=sc.nextInt();
		   }
		   for(int i=0;i<nv-1;i++) {
			   for(int col=i+1;col<nv;col++) {
				  ab=(String.valueOf(arr[i])+String.valueOf(arr[col]));
				  ba=(String.valueOf(arr[col])+String.valueOf(arr[i]));
				  if(Integer.valueOf(ab)>Integer.valueOf(ba)) {
					  col=col+1-1;
				  }else {
					  int temp=arr[col];
					  arr[col]=arr[i];
					  arr[i]=temp;
				  }
