Chapter 14 Two Brushes
Too inefficient?Is there another way?
According to Luo Cong's experience as a Chinese class representative in high school, this is the fastest way!
What's more, each horizontal row of university classrooms has eight seats at most, and four seats at least.With so many people in the classroom, isn't the easiest way to divide them into thirds and pass them from the front row to the back?
Han Yan'an ignored her doubts, but aligned all the materials on the table, pinched the left side with his right hand, and slowly moved his thumb up.

Luo Cong watched the materials one by one and quickly slid down from his thumb, and couldn't help humming twice in his heart.Papers fall so fast, can he see how many sheets have fallen?
But in the next second, she couldn't laugh anymore. At the moment when a certain card fell, his thumb stopped immediately!

What's going on, can he really see clearly?

Immediately afterwards, Luo Cong watched in astonishment as Han Yan'an put the fallen materials aside, counted them three times, and divided all the materials into four parts!

What...what's the situation... Not every seat in this classroom is filled with people, and he doesn't even look at it, so how can he know how many sheets are in each?
The get out of class time is coming to an end, and the students who went out to the bathroom gradually came back.

Han Yan'an took a glance, walked straight to the first row on the right, and put one of them on the desk of the classmate closest to the wall.Then he took out another copy and distributed it to the rightmost student in the middle row, the third to the leftmost student in the middle row, and the last one to the student in the left row closest to the wall. podium.

"The row in the middle is divided into two parts, so that we have four parts. Every student who gets the materials, first looks at his right hand or left hand side plus how many people he has in total, and then leaves a few materials, and puts the rest Pass it on later. After passing it on to the students behind, you will distribute the extra materials to the students around you."

As soon as his words fell, everyone suddenly realized the "ang" and started to act.

Luo Congcong stood behind him and looked at his back, blinking stupidly.

No wonder he said her method was too inefficient. There are eight seats in each horizontal row in the middle, and it would be too slow to pass one by one to the side and then to the back.And his method not only doubles the time, but also reduces the probability of "a certain row is redundant".

It is not a very clever method, but it is the most effective method.

Luo Cong couldn't help pulling her hair in regret, why didn't she think of it?She used to distribute materials like this every time in the history of literature class before, and she was stupid so many times after doing it for a long time!

The materials have been sent out, and since there are no students who skip classes, the number is just right.At the same time, the class bell rang just in time, Han Yan'an walked towards his seat with his long legs, and Luo Congcong hurried back to Susu's side.

"Okay, everyone has the information, right? Now take a look at the contents of the information..."

Professor Huang started to give a lecture. Luo Congcong looked at the materials lying flat on his desk, because under the materials was her textbook, and there was a broken pen in the textbook.From Luo Congcong's point of view, the right side of the document is bulging, as if some treasure is hidden.

The image of Han Yan'an counting the materials just now flashed in his mind, Luo Cong could not help but look at the white shirt who was concentrating on listening to the class, and a word came out of his mind inexplicably.

"Yo Yo, I didn't expect this guy to have two brushes!"

　Have you grabbed the five blessings yet?
