Street fortune tellers, how to "know your last name without asking?"

The original text comes from the official metaphysical manuscript.

I don't know if you have such an experience. There are usually some "wandering masters" up and down the overpass, beside the railway station, or near famous mountains and rivers. Some experts can even know your last name. Of course, there are also some real masters, and here are only some so-called "masters" tricks.

First, arrange all surnames into a square. For example, if there are a hundred, they will be arranged in ten rows, with ten in each row.

Then copy each line of words on a card and give each card a singular name. ( 1,3,5,7......)

Then copy the words in each column on a card and name each card with an even number. (2,4,6,8......)

At this time, he has 20 cards in his hand, and any odd card and any even card combination has only one surname. At this point, the props are complete.

The next step is to recite that side (usually a hundred surnames).

Finally, we can finally set up a stall.

(Tell him the line in the box). I'll show you the even card and let you find the last name. (equivalent to telling him which word the column in the square matrix is). Then pretend to measure your fingers. There will be enough time to solve this problem.

In fact, this is a math problem in junior high school or even primary school, and I have to admire the means of those "masters". They are really smart, apply what they have learned and make a fortune.

Of course, the above content is just a paragraph for everyone to see. As for whether there are experts who can really work out other people's names, I think there should be.
