Ovuvuevuevue Enyetuenwuevue Ugbemugbem Osas just got some writing homework to do.
His teacher gave him some texts, then asked him to write all of these texts once, and by hand.
However, Osas wants to cheat, so he ask you to write a program to repeat these texts exactly once so that he can just print them onto an A4 paper and turn in the homework easily.
(Although you know that finish the work by computer and printer, he will definitely get a ZERO, however, you still have to complete your task to get your AC.)
The input contains a lot of texts. You don't know when will the text ends, but you know that there must be EOF at the end of the input.
And you know that the total amount of characters won't exceed 107.
Print exactly the same as the input, even spaces and wraps('\n').
