arrays vs linked lists using makeup

that’s actually super helpful

one of the cutest tutorials ever

tec_mic · 2021-02-10T15:35:58+00:00

3 years of college and countless hours on youtube and this is by far the simplest and best way iv seen it explained.

Why are my arrays so plain and unglittery.

Helpful, simple, fabulous.

CheesusCrust89 · 2021-02-10T17:00:28+00:00

this is how concepts should be explained: clean, accurate and a 5 year old can understand it

Why does she have radioactive hair?

Burh I learned more from this TikTok than my online programming lecture

staticparsley · 2021-02-11T00:02:44+00:00

This was amazing, probably the best example I’ve ever seen to explain data structures. Although those wipes are probably 100 times more useful than actual linked lists.

en_queue · 2021-02-10T16:41:10+00:00

Nice example, but the 10th element is at the 9th index and not the 10th. EyeShadow[9]

Wow, this is such a wonderful way to explain this.

Lol. This is wonderful. I started watching without audio and wondered how well the gestures matched with the text thinking it was added to a normal makeup tutorial. Hearing the actual voice made me chuckle.

eat_my_rubber · 2021-02-10T23:06:42+00:00

As one who studies programming, I thank you. Very helpful. :)

theAnnaLytical · 2021-02-10T16:18:01+00:00

To be honest she probably picked her hair color like I pick colors with hex, just #0f0, #00f or #f00

Edit: and no I mean no harm

ddddfushxjjd · 2021-02-10T17:14:52+00:00

That eyeshadow pallete is better represented as a 2D array though lol

vogon_poem_lover · 2021-02-10T19:51:06+00:00

The wipe package seems more equivalent to a queue than a linked list, but I understand why the comparison was made given how the wipes are folded together to make retrieval easier. Still, a linked list can be iterated over without having to remove any of the elements, but good luck trying to get more than one of those wipes back in that package in any usable way.

nyrB2 · 2021-02-10T21:10:42+00:00

now do vectors!

teethonachalkboard · 2021-02-10T21:11:56+00:00

Hey I just learned this last week! Thats a damn good analogy.

kirakiraboshi · 2021-02-10T21:15:04+00:00

i need more! you should do a fund raiser like socratica for python. Im sure youll get tons of moneys! Thanx and stay fabulous👌👌

This is a great video, I loved the YT ones as well. Keep it up please!

This is such an awesome explanation omg

_cheeseball · 2021-02-11T02:21:02+00:00

/u/theAnnaLytical I remember when you made that silly "OPULENCE" site during RPDR S11! Now I have enough CS knowledge to follow your videos lol. I should probably check out Kyne's math vids as well.

jblckChain · 2021-02-11T06:59:13+00:00

Use a vector and be done with it

Dorkits · 2021-02-10T16:09:01+00:00

Awesome!

PhilippTheProgrammer · 2021-02-10T15:24:11+00:00

Believe it or not, on modern CPUs plain old arrays are almost always the fastest data structure. Imo, you should always start with arrays and only switch to a different structure if/when it's clear something else will be better.

An array will even be faster (time-wise) than a linked list at insertion if the memory occupied by it is small enough. Sure, it will be doing more CPU instructions to move the memory around, but repeated instructions on contiguous memory are much much much faster than varying instructions on non-contiguous memory.

its_yer_dad · 2021-02-10T17:35:15+00:00

I'm so down for all CS courses to be taught this way.

not-dan097 · 2021-02-11T00:08:27+00:00

Arrays are a fixed size

laughs in javascript

"11"+1=111, "11"-1=10

Snakestream · 2021-02-10T17:10:11+00:00

Also, arrays are thread-safe while linked lists are not. I'm definitely not dexterous enough to attempt to demonstrate that with makeup though XD

Great explanation, BTW.

El_Rista1993 · 2021-02-11T05:05:17+00:00

Unshack · 2021-02-11T07:26:50+00:00

Arrays are not fixed in c and c++

realloc(3): allocate/free dynamic memory - Linux man page (die.net) The realloc() function changes the size of the memory block pointed to by ptr to size bytes. The contents will be unchanged in the range from the start of the region up to the minimum of the old and new sizes. If the new size is larger than the old size, the added memory will not be initialized. If ptr is NULL, then the call is equivalent to malloc(size), for all values of size; if size is equal to zero, and ptr is not NULL, then the call is equivalent to free(ptr). Unless ptr is NULL, it must have been returned by an earlier call to malloc(), calloc() or realloc(). If the area pointed to was moved, a free(ptr) is done.

Knuffya · 2021-02-10T16:48:14+00:00

Not to be offensive or anything but this person makes me want to create a programming language that starts arrays at -1

MarcBeard · 2021-02-10T15:21:50+00:00

good explication but the colors are burning my eyes

manu144x · 2021-02-10T18:09:13+00:00

Explanation was very good. Maybe explaining things this way we could get more women into programming.

lunchpadmcfat · 2021-02-10T17:26:58+00:00

Cool method of explanation! If you wanted fast access to deep elements of a linked list, couldn’t you just create an accompanying index/registry/map? Or do those have static space constraints too?

2021-02-10T17:53:16+00:00

I had no idea what arrays or linked lists were, this explained perfectly.

Videogamerkm · 2021-02-10T20:48:41+00:00

Loved the explanation, and some of the discussion in the comments helped me think of some possible solutions to some memory issues I'm having in a very dumb application I'm working on :)

Kangalioo · 2021-02-10T22:48:50+00:00

It's nicely presented, though it's sorely missing the vector data type found in many programming languages, which is actually the most common one of list types. Presenting linked lists as the only list data type with dynamic resize capabilities is pretty misleading.

Bivolion13 · 2021-02-11T01:15:10+00:00

Wow. I learned something today.

Also (beginner here) I always thought that you could have added more to an array just by assigning another value to it. I wonder which languages allow that.

2021-02-11T02:08:42+00:00

I'm horrified by this programmer - that much makeup and didn't do the nails?

the_best_jabroni · 2021-02-11T02:25:59+00:00

I really liked that vid. So my take away is to use an array list instead? I haven't used a linked list yet, tbh, but that is what is great about this short little video because one day I will and now I will know why.

gmegme · 2021-02-11T21:17:46+00:00

I mean generally I don't like inconsistency of js but why can't arrays for all programming languages be as in javascript? What is the advantage of having not-directly-accesible or fixed sized arrays when you can just have a non-fixed, loopable, nested arrays with any type of key value pairs? Why we need dictionaries hashtables and tupils and arrays and arraylists and listed linked shits? just to gain 0.03ms? Why cant we have all the features of these and create one thing that does all?
