Reverse Sentence

Given a sentence, reverse the order of its words. Words are defined as continuous sequences of non-space characters. Any extra spaces in the input should be ignored. Formally, if the input sentence is given by ( S = w_1 \ w_2 \ \ldots \ w_n ) then the output should be ( w_n \ w_{n-1} \ \ldots \ w_1 ).

outputFormat

Output the sentence with the order of words reversed. Words should be separated by a single space and no leading or trailing spaces should be present in the output. The output is written to stdout.## sample
