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

本程序包括多组測试数据;
输入数据的第一行是一个整数N，然后是一空行，后面跟着N个数据块，每一个数据块的格式在程序描写叙述中说明了，数据块中有一空行。
输出格式由N个输出块组成，每一个输出块之间有一空行；
输入描写叙述：
现给你多组測试数据，第一行是一个正整数，表示接下来測试数据的组数，每组測试占一行，包括一串单词，中间用一个空格隔开，每一个单词仅包括大小写字母；
输出描写叙述：
每组測试数据都打印在一行上；
