Problem: Given an input sequence. You have to write a program to sort it in non decreasing order.

Input
First line of input T has number of test cases followed by T test cases.
Each test case has two lines. First line has a number N. The second line has N space separated elements as an input sequence

Output
Output has T lines of output corresponding to each test case.
Each line will have space separated integers in non decreasing order.

Example

Input:
3
2
3 4
5
1 4 5 8 2
1
7

Output:
3 4
1 2 4 5 8
7

Solution (in PYTHON):

Solution:
t=input()
for _ in xrange(t):
    n=input()
    a=map(int,raw_input().split())
    a.sort()
    for i in a:
    	print i,
