#include<bits/stdc++.h>
using namespace std;stack<char> q;void print(){while(!q.empty()){cout << q.top();q.pop();}
}int main(){int n;cin >> n;cin.ignore();while(n > 0){string s;getline(cin, s);for(char c : s){if(c == ' '){print();cout << ' ';}else {q.push(c);}}print();cout << '\n';n --;}return 0;
}
