## Problem Description ##

Ignatius likes to write words in reverse way. Given a single line of text which is written by Ignatius, you should reverse all the words and then output them.

## Input ##

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.

##     ##

## Output ##

For each test case, you should output the text which is processed.

##     ##

## Sample Input ##

3  
olleh !dlrow  
m'I morf .udh  
I ekil .mca

## Sample Output ##

hello world!  
I'm from hdu.  
I like acm.  
  
\[hint\]  
Remember to use getchar() to read '\\n' after the interger T, then you may use gets() to read a line and process it.

        getchar();
        while(n--)
        {
            gets(a);
            l=strlen(a);
            for(i=0;i<=l;i++)
            {
                if(a[i]==' ')//每次遇到空格则逆序输出到前一个空格或开始字符
