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

#include<cstdio>

#include<iostream>
using namespace std;
void _S()
{
    char s[];
    int num=;
    char c=getchar();
    while(true){
        if(c=='\n'){
            for(int i=num;i>=;i--) cout<<s[i];
            cout<<endl;
            return ;
        }
       s[++num]=c;
       c=getchar();
    }
}
int main()
{
    int n;
    scanf("%d\n",&n);
    while(n--)
        _S()
    return ;
} 

为什么感觉题目没有解释很清楚，让那么多人PE。。。。。。。。。。。

当然本题处理方式有很多，也可以每一行输入后再处理。个人属于习惯单个字符输入的那种（此时要注意过滤换行符什么的）。
