jjjjj doesn't like long description.
Given several sentences, please modify the sentences so that the order of the words is reversed.
There are multiple lines in each test case.
Each line contains a sentence with several words, or there may be no word within it.
Each word will be separated by one or several whitespace.
Also, whitespaces may appear in the front or in the back of the sentence.
It is guaranteed that:
For each sentence, please output the modified sentence with the reverse sequence of words.
Attention:
(1) After modification, each word is separated by only one whitespace.
(2) If there is no word in the sentence, you still need to output '\n'.
