Problem: Doraemon gave Nobita a gadget that swaps words inside a string in the following manner :

If there are W words, word 1 is swapped with word W, word 2 is swapped with word W-1 and so on.
The problem is that Nobita himself cannot verify the answer for large strings. Help him write a program to do so.

INPUT : 
the first line of the input contains the number of test cases. Each test case consists of a single line containing the string.

OUTPUT :
output the string with the words swapped as stated above.

CONSTRAINTS :
|string length| ≤ 100000
string contains english alphabets and spaces

SAMPLE INPUT
1
hello world

SAMPLE OUTPUT
world hello

Solution (in PYTHON):

Solution:
def swap(a,b):
	a,b=b,a
for _ in range(input()):
	arr=list(map(str,raw_input().split()))
	i=0
	length=len(arr)-1
	half=(len(arr)-1)/2
	#print arr
	#print length
	#print half
	'''
	while i<=half:
		arr[i],arr[length-i]=arr[length-i],arr[i]
		i=i+1
	'''
	arr=arr[::-1]
	for item in arr:
		print item,
		
	print ""
