How do five security guards arrange duty? One person works the day shift and two people work the night shift. The day shift is from 8 pm to 16 pm, and the night shift is from 16 pm to 8 pm the next day. It is urgent. I have a regular shift every five days to ensure that everyone works one day and two days every five nights. I have no objection to splitting up and combining work and rest. These five people use abcde to represent day shift abcde night shift EB AC BD CE DA, I hope it will help you!
