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<iostream>
#include<string>
using namespace std;
int main()
{
	string str;
	int T;
	(cin>>T).get();
	while(T--)
	{
		int begin,end;
		getline(cin,str);
	    begin=end=0;
		for(int i=begin;i<str.size();i++)
		{
			if(str[i]==' ')
			{
				end=i;
		      for(int j=end-1;j>=begin;j--)
				cout<<str[j];
			     cout<<" ";
				 begin=end+1;
			}
		}
		for(int k=str.size()-1;k>=begin;k--)
			cout<<str[k];
		cout<<endl;
	}
	return 0;
}
