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.

题意：输入一个字符串，将字符串中的 单词反转后输出，一次反转一个

#include<stdio.h>
#include<iostream>
#include<memory.h>
#include<string.h>
#include<stack>
using namespace std;
int main(){
    int n;
    char ch;
    cin>>n;
    getchar();
    while(n--){
        string s;
        stack<char> stack_s;
        int index=0;
        while(true){
            ch=getchar();
            if(ch==' '||ch=='\n'||ch==EOF){
                while(!stack_s.empty()){
                    printf("%c",stack_s.top());
                    stack_s.pop();
                }
                if(ch=='\n'||ch==EOF)
                    break;  /*绝对不能少，控制输出结束*/
                printf(" ");
            }else{
                stack_s.push(ch);//入栈

            }

        }
        printf("\n");

    }
}
