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 = int(raw_input())
for t in range(T):
	n = int(raw_input())
	a = map(int, raw_input().strip().split(' '))
	a = sorted(a)
	print ' '.join(str(i) for i in a)
