The shuffling of the order at the beginning is a trick. It does not affect the successful pairing of the final group, but only affects which two pairs are finally matched.
After tearing the two halves, stack them in order. At this time, the order of the cards is abcda'b'c'd'. Here x and x' are paired.
If p(x) is used to represent the position of x from left to right, the mathematical expression is p(x) = p(x') mod 4.
Note that the number of words in the name here is not important. No matter how it is rotated to the end, the above one The formula will not change. (If you don’t understand these two sentences, you don’t have to read them. The main thing is to understand that they can be paired first.)
At this time, the three pictures on the top are inserted in the middle. The purpose is to ensure that the first picture and the last picture are matched. It is also derived from the formula. inference.
note, insert in the middle, insert in the middle, insert in the middle . Post important things three times. Can't put it last.
Here Liu Qian said that you can insert them however you want, which means you can mess up these three pictures and put them in the middle.
At this time, the result of the magic has been determined, which is the first and last picture in the current queue.
The next step is to collect the first picture. There are still seven cards in hand, and the matching card is the last one.
Then insert the number in the middle according to the number of southerners and northerners. This step does not matter. Because the matching card is the last one, it does not affect it.
means that you don’t have to do this step.
Next, you may throw away 1 or 2 cards, leaving you with 5 or 4 cards. But the matching piece is still at the end.
It has nothing to do with gender. If you are a man, you can throw two, and if you are a woman, you can throw one.
Liu Qian said that everyone is confused in different ways, - no, everyone's last picture is what you want.
Next, rotate according to the number of words in "The Moment of Witnessing Miracles". It doesn't matter what is included here. What is important is that these are 7 words.
If you want, "I want to make a fortune in the Year of the Dragon" is fine.
If there are 5 cards left, after this rotation, the rotation card will be the 3rd one.
If there are 4 cards left, after this rotation, the rotation card will be the first one. Behind
are the deletion rules, which are a bit like Joseph's problem. Those who are interested can search for related knowledge.
If there are 5 cards, the arrangement is abxcd, and x is the matching card. Then the rule for her deletion is:
The first time: axcd
The second time: axd
The third time: xd
The fourth time: x, successful
For example, four cards:
If there are 4 cards, the arrangement is xabc, and x is the matching card. Then the deletion rule is:
The first time: xbc
The second time: xb
The third time: x, successful
Therefore, Xiaoni must have inserted it wrongly, or thrown it away wrongly. When inserting the middle, be sure to put it in the middle.
