What Alex did with 53 seconds

[@elmepo232]

They finished the problem in about the time it takes me to read it

[@juanmacias5922]

lol that's because you weren't looking for the main points. ;D

[@illegalsmirf]

You think maybe it's a kind of gamified situation where the 'pros' know what to do before the 'competition' already starts? Seems like an obnoxious event filled with obnoxious foulmouthed people.

[@juanmacias5922]

@@illegalsmirf one thing I've learn from life is you get what you put in, there are many people that do it for the fun of it, and take their time to read the story, as its plot is elaborated on within the 25 days. Edit: grammar

[@illegalsmirf]

@@juanmacias5922 Yes of course. Although the fact that there are leaderboards tells you a lot more about human nature and the main reason why most people take part. And of course, many people take more out of life than they put in. I would also say that not everyone gets the chance to put in as much as they would like, either. Very complicated is life. I have often thought living is more trouble than it's worth!

[@juanmacias5922]

@@illegalsmirf ha yeah, it kind of sucks when you realize competition is at the root of our existence, we compete for love, education, and financial standing. I was never a fighter, which could be why my life isn't what I wanted it to be. But I choose to see beauty in the small things, and I think that's why I enjoy doing AOC, it gives me an avenue to see that my programming chops are growing. My goal is to collect all 50 stars (2 per day) one year, but this year I want to be consistent and get all the part 1 stars. :D I think we might as well find some solace in this world, and I find AOC cozy and fun. :) Also, responding to the original question, I forgot they highlight the main points, so it's very easy to skim the highlighted section and see what the problem is asking!

[@kausee]

Thanks Kay. Appreciate your efforts in making these videos. These are my highlights of the day!

[@alexwennerberg]

So excited for advent of code! I’m going to do mine in Scheme :)

[@juanmacias5922]

I was thinking of using C++ but I just got reminded how much string parsing is involved haha ugh...

[@juanmacias5922]

Wow, Alex is a badass. Thanks Kay, looking forward to more videos about dealing with tough puzzles.

[@MemeConnoisseur]

Can't wait for the videos 💪

great video again, very cool to watch, as always 🙂 ... you have find a great way to explain complex things very well

[@tau9632]

Omg I'm going to *love* this series! It even made me realise that something I thought I was 'naturally' bad at (working under pressure), could actually be trainable, could be improved and I don't need to feel so insufficient anymore!

[@RavitShrivastav]

i never quite liked coding puzzle since college. makes me too anxious but your pov on how it could be fun even when difficult. very Feynman esque

[@Revoker1221]

An interesting coincidence you should mention Feynman, Angela Collier uploaded a video 2 days ago titled "the sham legacy of Richard Feynman", it's over 2 hours long and goes over the problems surrounding how Feynman is remembered. Heck, it even brings up the "Feynman method" to learning was invented out of thin air and likely had nothing to do with Feynman. Not much substance to my comment, sorry. I just wanted to share how curious a coincidence it was, and if anyone has a spare afternoon to waste and enjoys physics, Angela Collier is a nice channel.

[@tau9632]

@@Revoker1221 Hahaha I wanted to comment the same thing. I guess this usage of Feynman-esque here is fine, since it's about the (non-problematic) side, of just enjoying science and being passionate about problems.. but initially the word 'Feynman' leaves a bad taste in my mouth now...

[@ExCyberino]

I luv you and luv what you do. I don't fully watch, because I'm too eager to code and study, but i know it's good .

[@waso-mu]

That's my friend! Yay!

[@zionklinger2264]

That chaining functions syntax is very common in rust. it's also pretty great and, I would say, the preferred way to do most data transformations in rust.

[@ellyse7777]

Excellent vidéo !

[@Dizzykitty817]

I feel this is the type of skill that recruiters expect for new grad positions.

[@isak]

Great video as always! :D

[@sreejithmmsj]

How did he read the puzzles so fast ?

[@jamesarthurkimbell]

People who do these challenges for speed are focused on recognizing what kind of algorithm a question is hinting at, without having to read the whole thing. Then sometimes it takes a second or third try, like we see in the video, but that's only a few seconds more.

[@MindGameArcade]

it's similar to 'competitive programming' (look it up online) there is honestly nothing impressive about it, just by going over the puzzle you already know what kind of problem it is & you just spit out a premade solution. I assume Kay is not familiar with competitive programming. Here the program was just finding a maximum which is extremely trivial, but in competitive programming you have people solving NP problems in a matter of seconds simply because it is always the same category of problems, you don't read all the fluff of the problem.

[@Bibi_effin_Blocksberg]

Well, I mean technically if you're used to this and you actually know Day 1 doesn't involve a lot of complexity you can just focus on finding the main question, the data, and off you go. That doesn't work so well with nuanced Problems where more context is involved, but with isolated problems like this, and if you've trained and it's your goal to be fast, it doesn't seem too far off. I guess most people could get there, if they were interested in it. Still quite the impressive skill, you don't get there without putting effort into this.

@@MindGameArcade what's your rank in codeforces? or any competitive programming site

[@xspager]

Tired my hand at the 2013 one a few months ago and I to stop after solving the first part of day 3 to see how smart people were solving it. Need to get back to it. Also, in case Alex need to and read this: she rules!

[@anon_y_mousse]

I had to download it just to read the code since KZbin is still shitting on me at 360p, but it's kind of funny that he just swapped to the JavaScript console of the browser to code it. Just a simple scratch bit of code and problem solved. Although, I do wonder how long it would take using C. Granted I have scads of libraries to make use of, still have to type in include directives and file names, then boilerplate junk that you don't need in most other languages. I did it last year and was bored after day 3, but I think I'll at least give it try again this year. Are you going to make a video for each day of AOC?

[@gideon0223]

In the video you make the comment that method chaining would not be acceptable in the real world. Why not? In a lot of functional languages we basically pipe / chain mathematical operations or transformations all the time.

[@neoeno4242]

Method chaining is definitely fine in a regular job - what would be highly unorthodox is adding new methods to builtins the way Alex is here. So for example adding a `num()` method to the array builtin which converts every item in a list of strings into a number - that sort of thing. Very useful/appropriate in this context, but in most working teams would be rejected.
