Which ones played a certain sound, and what happened to the people in a certain hand?

Huang Yaoming, Song of the Four Seasons.

Huang Yaoming, Song of the Four Seasons.

Lyrics: Lin Xi Composer: Deng Yuxian.

The red sun breeze blows the seedlings, and the birds in the clouds know the spring dawn.

Which loves to dream When I woke up, the butterfly flew away by the bedside.

The boat rocks briskly at the bottom of the bridge, and you know how much wind and rain you have on the bridge.

Half singing, half harmonic A ballad The lotus flowers on the lake are beginning to bloom.

The four seasons are like songs, there are cold and warm, coming and going, racing against time.

It's like a windmill that can't stop making your heart beat.

The four seasons are like songs, there are cold and warm, coming and going, racing against time.

It's like a windmill that can't stop making your heart beat.

The flowing water under the bridge catches up the tide and the yellow leaves jump gently in the wind.

Hurry up and sleep with the moon, the stars shine, and stare at whomever to laugh secretly.

Where did the immortal shake the fan and leave the frost and snow behind.

Ants have burrows, their homes have a door, and the wind howls outside the door.

The four seasons are like songs, there are cold and warm, coming and going, racing against time.

It's like a windmill that can't stop making your heart beat.

Make your heart beat Make your heart beat.

How can it be. Some people were told a few times and later corrected. Some people are still like that. Some people may have gotten involved with the person who said him.

Hello, if you have lost interest in a certain platform, then you may as well switch to another platform. Changing places may have a new mood.

It's normal that everyone has a different platform, and the preference for a certain platform changes over time.

It's not that I lost interest, but I never mentioned it.

If you don't have an interest, I think you can look for another interest, because basically everything in the world is something that we can like.

There are many things that can be done beyond a certain hand and a certain sound.

Me too, but I can do something else.

If you have lost interest in something, then you can develop new interests, we all have our own attention, and when we lose interest in the things we focus on, then we can focus on other things that we like.

Because you have lost interest in a certain hand, it means that you have matured and know what you need.

Just don't listen to it, although there may be a lot of people around listening to it, but if you don't like it, you can put on headphones and listen to your favorite songs. Some ** platforms really don't dare to compliment, and some plagiarized songs are also full of loopholes, so try not to listen to yourself, don't interfere too much, since they have all been exposed for plagiarism, it's almost cool.

Somebody is guilty of something, too.

And the connotation, to be precise, belongs to a certain article, and the content is slightly yellow, and Zhang Yiming also admitted.

Then Duan You didn't have a family to mess with.

It is said to have been done by an Antarctic penguin.

Generally, singing on the software is not good without a sound card, there is a sound card installation driver to tune the sound effect and sing the song is beautiful and beautiful, you feel that the sound card does not feel that you must be without the sound card sound effect, the general installation master will give a good tune, there are many kinds of sound effects, you find a suitable one.

Separate sound card for your computer. Plus a phone sound card converter. These are all undubbed.

I don't know what brand and model of your sound card is.

Generally, while having equipment, you also have to have some singing foundation, if you need effects, the sound card basically has some sound effects that come with it, and you can adjust it according to your own needs.

Buy a better and more expensive sound card, cheap quality is not good.

Of course, you have to play it all. Unless the last note is an open string, you can change your hand ahead of time.

Generally, it is played all, but there are special circumstances, depending on the situation.

If the first student wants to shake hands with 50 classmates, then the second student does not have to shake hands with the first student, then he has to shake hands with 49 classmates, then the third student does not have to shake hands with the first and second classmates, then he has to shake hands with 48 classmates, and so on, the total number of handshakes is 50 + 49 + 48 + 47 + 46 +...+3+2+1=(50+1) 50 2=1275 (times).

A total of 13 people attended the meeting.

Analysis: Suppose there are n people in the meeting, the first person shakes hands with n-1 people, and the second person shakes hands with n-2 people,......And so on, the penultimate person shakes hands with 1 person, and the last person shakes hands with 0 people, so the number of handshakes is (n-1) + (n-2) +....1+0=78

According to the first n terms and the formula, [n-1)+0]*n 2=78, we get n = 13, n = -12, and only 13 satisfies the condition, so n = 13, there are 13 people attending the meeting.

There are a total of n people.

The first person has to shake n-1 times, and the second person only needs to hold n-2 times, because he no longer needs to shake with the first person.

So it's 1+2+3+...... in totaln-1＝78

It's simple, it's n*(n-1) 2=78

As soon as you get to know it, n = 13, there are a total of 13 people in the meeting.

Suppose there are x people, then the first person has to hold x-1 hand, then exclude the first, and the second person x-2 times ,......The last 0 times.

That is, the sum of a series of equal differences. 1 to x-1, (x-1)(1+x-1) 2=78, solved, x=13 or x=-12 (rounded) hehe.

30x29 2 = 435 times.

Each of the 30 people shook hands with the other 29 people, but here each person double-counted, so it should be halved.

30 people, each person out of their own and 29 people shook hands, so it was 30x29
