King Albert, the King of Einstenia decided marry off his second daughter, Elvira to Isaac, the Prince of Newtonia. However, he wanted to test whether Isaac was worthy of Elvira or not. So, he locked him in a room with 6 doors - P, Q, R, S, T and U. Three of these rooms were labelled as entrances and three were labelled as exits. King Albert entered the room through door P and  his Chief Minister entered through door U. King Albert told him that in order to pass the test he needed to pass through every door, but just once and that too in a particular order such that the exit is used as an exit only and an entrance only as an entrance. Also, door P is followed by door Q or door T, door Q by door R or door T, door R by door S or door U, door S by door P or door U, door T by door Q or door S and door U by door R or S. Saying so, King Albert and his Chief Minister exited through door Q and unlocked all the doors. In which order should Prince Isaac pass through the doors?
