Timer is Running

Given an array A of size N containing 0s, 1s, and 2s; you need to sort the array in ascending order.

The first line contains an integer 'T' denoting the total number of test cases. Then T testcases follow. Each testcases contains two lines of input. The first line denotes the size of the array N. The second lines contains the elements of the array A separated by spaces.

For each testcase, print the sorted array.

1 <= T <= 500
1 <= N <= 106
0 <= Ai <= 2

Input :

0 2 1 2 0
0 1 0

0 0 1 2 2
0 0 1

Testcase 1: After segragating the 0s, 1s and 2s, we have 0 0 1 2 2 which shown in the output.

** For More Input/Output Examples Use 'Expected Output' option **
