 咳咳，这个是为了赶量

需要注意的就是输入方式，别的也没什么难点

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.
这是题意
接下来放代码

#include <iostream>
#include <cstdio>
#include <stack>
using namespace std;

int main(){
int n;
cin >> n;
getchar();
while(n--){
stack<char>cst;
while(1){
int ch=getchar();
if(ch==‘ ‘||ch==‘ ‘){
while(!cst.empty()){
cout << cst.top();
cst.pop();
}
if(ch==‘ ‘)cout << ‘ ‘;
else break;
}
else cst.push(ch);
}
cout << endl;
}
return 0;
}

OK
