Hotel front desk reservation, 6 people go to work 24 hours a day. What is the most comfortable arrangement?

D stands for day shift (7: 00 am-65438+09: 00 pm); N stands for night shift (19: 00pm-7: 00am); O stands for rest

Remarks: Two people work the day shift and one works the night shift; Working hours 12 hours, with rest;

But there are three shifts a day (two day shifts and one night shift), that is to say, three shifts a week * seven days =2 1 shift, while one person works four shifts a week, and six people work four shifts * six people =24 shifts, which is three shifts more than the planned 2 1 shift. So if you arrange three classes below, you can arrange the rest.

One, two, three, four, five and six days.
