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.
 

#include<cstdio>
#include<stack>
#include<cstring>
using namespace std;
int main(){
    int t;
    scanf("%d",&t);
    getchar();//吸收回车
    while(t--){
        char x;
        stack<char>f;
        while(1){
            x=getchar();
            if(x!=' '&&x!='\n'&&x!=EOF) f.push(x);
            else{
                while(!f.empty()){
                    printf("%c",f.top());
                    f.pop();
                }
                if(x=='\n'||x==EOF) break;
                printf(" ");
            }
        }
        printf("\n");
    }
    return 0;
}

用C字符串流代码如下：

#include<cstdio>
#include<sstream>
#include<iostream>
using namespace std;
int main(){
    int T;
    string s,ss;
    scanf("%d",&T);
    getchar();
    while(T--){
        getline(cin,s);
        int x=0;
        while(s[x]==' '){//开头可能有空格
            printf(" ");
            x++;
        }
        istringstream sin(s);
        while(sin>>ss){
            x+=ss.length();
            for(int i=ss.length()-1;i>-1;i--)
                printf("%c",ss[i]);
            while(x<s.length()&&s[x]==' '){//中间空格可能不是一个
                printf(" ");
                x++;
            }
        }
        printf("\n");
    }
    return 0;
}
