PROGRAMMING:Kwai Fu
Kwai is a relatively short video app software, which updates some interesting videos every day, so its appearance has become a way to kill time. But some of our students will not stop watching interesting videos when they come in and cause them to indulge in it. When you enter and exit Kwai app, its background has a record data, that is, the time to enter Kwai and the time to exit. Kwai Kwai Kwai is now in charge of your class. You need to know who you have the longest time in your day. So you asked for the backstage data of your class, but these data are scattered. Please help your head teacher find out the fast maniac in your class.
