HDU1062:Text Reverse

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.

int main()
{
    int n,i,k1,k2;
    char data[];
    cin>>n;
    getchar();
    while(n--)
    {
        k1=;k2=;
        gets(data);
        for(i=;i<=strlen(data);i++)
        {
            if(data[i]==' '||data[i]=='\0')//找空格，为了找单词
            {
                k2=i-;//是空格前面那个词的下标
                for(k2;k2>=k1;k2--)//从K2一直打到k1这个词
                cout<<data[k2];
                k1=i+;//k1是下一个单词的开头的下标
                if(data[i]==' ')
                cout<<" ";
                if(data[i]=='\0')
                cout<<endl;
            }
        }

    }
    return ;
