There is still one year left in the first volume of the sixth grade math problem.
This is a full topic, and there is a * * * in 10! =10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 *1= 3,628,800 kinds of sequences. According to the teacher's meaning, when everyone is sitting in the currently arranged position, it will be * * * once every 3,628,800 days = 994/kloc. At that time, students and teachers have been dead for more than 9000 years, so teachers are playing tricks on people! Don't even think about taking a holiday! Unless teachers and students are monsters who have lived for thousands of years! But it is a monster that can learn for more than 9000 years! Ha ha!
