For each list of words, output a line with each word reversed without changing the order of the words.

This problem contains multiple test cases!

The first line of a multiple input is an integer N, then a blank line followed by N input blocks. Each input block is in the format indicated in the problem description. There is a blank line between input blocks.

The output format consists of N output blocks. There is a blank line between output blocks.

Input

You will be given a number of test cases. The first line contains a positive integer indicating the number of cases to follow. Each case is given on a line containing a list of words separated by one space, and each word contains only uppercase and lowercase letters.

Output

For each test case, print the output on one line.

Sample Input

1

3
I am happy today
To be or not to be
I want to win the practice contest

Sample Output

I ma yppah yadot
oT eb ro ton ot eb
I tnaw ot niw eht ecitcarp tsetnoc

题意：就是把输入的每个单词反转。

思路：就是一个个读入，一旦碰到空格输出，碰到回车，换行。

代码：

#include <stdio.h>
int main()
{
    char a[100],c;
    int i,j,n,m;
    scanf("%d",&n);
    while(n--){
        scanf("%d\n",&m);
        for(i=0;i<m;i++)
        {
            j=0;
            while((c=getchar())!=EOF)
            {
                if(c==' '||c=='\n')
                {
                    while(j--)printf("%c",a[j]);
                    printf("%c",c);
                    if(c=='\n')
                        break;
                    j=0;
                }
                else
                    a[j++]=c;
            }
        }
        if(n!=0)
            printf("\n");
    }
    return 0;
