未來簡單式

In this video, you're going to see me do a coding challenge.

This is a visualization of the recommendation number sequence.

I'll talk about what that number sequence is, how it works and then write the code to draw this using job script in the P five library.

This is all thanks to and inspired by a number file video, which I will also reference, and you can find links to in the video description.

So apparently it's spooky, so I look scary circles running away.

All right, so the idea for this coding challenge originates from this wonderful number file video about this thing called the record Monza sequence.

Now the recommend sequence is a numeric sequence, a sequence of numbers, and I am a kind of prison who really likes.

I keep a book, a 1,000,000 random numbers in it around.

It soothes me at night time when I'm feeling stressed or anxious just to read some random numbers.

And so this particular number sequence is a fascinating one, is invented by a Colombian mathematician named Bernardo.

Recommend Santos, and you can find out more about it at the guess what?

There's a website which is actually the online encyclopedia of integer sequences.

And I think now, possibly for the rest of my life, I'm just gonna be at home browsing this way.

I can't, but I didn't really know about this till now.

I'm not gonna go too much into the background of this numeric sequence or number sequences.

I've definitely recommend that you also check out the number file video.

Just gonna try to code it and visualize it.

And if I'm feeling a little saucy afterwards, I might I might do a video where we try to make something musical out of the number sequence.

How does that let me first attempt to just describe to you what the number sequences a number sequence is just exactly that.

A sequence of numbers like 123456789 That's a integer sequence counting up by one.

11235 eight right where you add the two numbers before and get the next.

So maybe you want to pause this video right down, invent your own number sequence.

This particularly recommend a number sequence is particularly beautiful and interesting as a kind of the strange balance between order and chaos.

So anything that has a thing dialectic quality of having both order and chaos is always fascinating to visualize.

All right, so let's say we have a number line and I'm really just regurgitating here.

A bit of the explanation that is in the number file video, in my own words, probably not nearly as well.

There's a little glare there, but I think everything will be fine.

All right, now let's say I have a counter, and that counter is going to start at once.

23456 Now, for every number in the counter, I'm going to try to go backwards.

But I thought if I guess I'm gonna start somewhere gonna start right here.

And I'm going to attempt to go backwards if I can go backwards by this number of spaces and land somewhere that hasn't been landed on before.

It seems weird, and I don't know if that explosion made sense, but it's going to make sense to you if you keep watching.

I think All right, so, one, I'm gonna try to go backwards.

There's no negative numbers in the sequence, so I can't go backwards.

So my sequence is now 01 Now I'm going to go.

I'm gonna try to go backwards by 3123 up.

1234 Now I'm gonna try to go back for 123 I guess what?

In the visual ization of it, I'm going to want to draw the moving backwards below in.

It's sort of the common way to visualize this sequence.

The point of me showing this year is the code it, But you might invent your own way of visualizing, but I could go back for now.

By the way, forgot to keep updating this 0136 two.

512345 So now I go here so we can see how this goes.

It's gonna be a bit easier for me to write a computer program to do this than for me to do this manly on the board.

First of all, I really, really hope that I didn't Bosch.

I'm gonna go check the encyclopedia and see if this sequence matches with their 0136 to 7 0136 to 7.

All right, so let's begin and write some actual code.

So here I am in a jobs program with P five gs library loaded.
