After working as a teacher for a long time, Mr. Xifu has finally decided to open a new school of his own. In his school, he wants to assure the highest comfort to the teachers. He has decided that any teacher will be able to take a class at any time he wishes and the classes of this school will not have any fixed duration other than the fact that a class can’t go on for more than 24 hours. In fact, classes can be happening even at midnight and classes may go over to the next day!
