The input contains several test cases. The first line of the input is a single integer T which is the number of test cases. T test cases follow.
Each test case contains a single line with several words. There will be at most 1000 characters in a line.

olleh !dlrow
m'I morf .udh
I ekil .mca
[align=left]Sample Output[/align]
hello world!
I'm from hdu.
I like acm.
题意:交换单词位置,每个单词之间有若干个空格隔开例如:“ asdas ghty,. yui ” 的对应输出为“ sadsa .,ythg iuy ”
AC代码如下:
