Two generations of love is a legend of Xinjiang Uygur people and the embodiment of wisdom. There is a story about two generations taking silver rings skillfully, which is almost a household name in Xinjiang. What it says is:

One day, rich man G said to employee M, "I have a seven-ring silver chain. If you work for me for a week, I will pay you a silver ring every day. Will you? "

M was dubious, and then G went on to say, "However, on one condition, this string of silver chains is connected one by one, and you can only break one at most. If you can't take away a ring every day, you won't get paid this week! "

M promised to try, but he immediately found that things were a little difficult, so he quickly went to the two generations and asked them to give him advice. Sure enough, the two generations of love came up with a clever way to let the rich G watch M take the silver ring. The greedy rich man finally got what he deserved and lifted a stone.

I hit my head on my own foot.

In fact, this problem of the rich man is not difficult. Without the help of two generations of superman wisdom, all the readers present can think of the following method, that is, disconnect the third link of this silver chain and divide it into three parts. The ring numbers of these three parts are 1, 2, 4 respectively.

In this way, employee M can take the single ring on the first day, return the single ring to take the double ring on the second day, take the single ring on the third day, return the single ring to take a string of four rings on the fourth day, take the single ring on the fifth day, return the single ring to take the double ring on the sixth day and take the single ring on the seventh day. At this point, all seven rings on the silver chain are in M's hands.
