Our class must be rescheduled. Is there any way to convince everyone? Some of us want to draw lots, but we are afraid that the tall man will sit in the front.

The whole class can be roughly divided into tall people and short people. The short ones sit in the first four rows and the tall ones sit in the last four rows. These four rows can take turns every week, with the first row sitting in the fourth row, the second row sitting in the first row, and so on ... The last four rows are the same, the fifth row sitting in the eighth row, and the sixth row sitting in the fifth row. ....

Because of the lighting problem, you can also change seats in turn every week in combination with the order of the left and right seats. For example, the first row by the wall can sit in the second row in the middle, the second row by the window in the middle, the second row by the window, and so on. ....

Said a lot, actually quite simple. This is the case in our class. No one has any opinions or objections. Taking care of everyone is science!
