Unfortunately, I'm limited on time, so I decided to not make explanations (unless people really want them). Google should release their solutions after the round. If you have questions, then you can ask them in the comments below and I will try to answer them.
I created a Discord server for discussions and more: / discord

Light is actually more optimal.

Idk if I’m more impressed with how quick he solves the problems, or his reading comprehension. Would take me at least 3 minutes to read the question, what a beast
Yeah my...well...every mental skill required to do well in programming is low...But even outside of programming, I've always scored frustratingly low at reading comprehension. I feel people understand things in text that aren't even written; you're just expected to infer and read between the lines...and I often feel I'm the only one among my peers who doesn't see the invisible text that everyone else does

For those feeling discouraged, it's simply the rule of 10000 hours. Do something for that long and you become good at it. This man, has devoted his time to master competitive programming since high school. Ask him to throw a baseball, dribble a basketball, or play advanced music - probably won't be able to. It's all what you and how much time you devote and how hard you work. So props to him, but it's not impossible. We all have this ability and potential.
and there s no 10000 hours rule

Honestly, this video inspires me. Every time I come back, I think of how much my knowledge has progressed compared to when I first watched it. I am still eons apart from the skill William Lin displays in this video, but man, it truly is fantastic to see how a lot of practice can take you far.
Same, the first time I watched this video I thought I was watching him type messages in alien language. Now if I pause i can actually read through the logic and understand what all he is doing but still so impressive how fast he came up with solutions
@@techbytes5 Dude, exactly what happened to me. I started learning C++ because of this video, and now I can understand some stuff. But before, it just looked crazy asf.

Don't forget he said "I thought the problems would be harder"
bro mad respect. Keep doing what you are doing. As a coder myself I can see how insane this accomplishment is. Greta job!!!!

Bruhh! Seeing the video is only 17mins and contest being 3hrs I thought this is a fast forwarded and clipped version, never thought he coded all of them in 17 mins. What a beast !

Bro, I'm literally just starting to learn programming and seeing you work is insane.
I might quit trying to learn programming. This looks too tough. Are you learning coding with a boot camp btw?
@@jv1192 dude, competitive programming is not required for getting good jobs at good it companies (in majority of cases). the reason is that competitive programming requires different skills from the real world (you will never ever have at your job a binary string, with some operation defined on it, asking you to maximize / minimize some quantity). don't quit because you don't know some **esoteric** algorithms.
to be clear, there are some jobs where you need to have some strong as search engine - programming or high performance computing, but they do not constitute the majority of the job market out there.
@@ksidnis9648 what jobs do not require you to move as fast as him? I’m confused as to what job I should be working towards because I only know HTML, CSS, JAVASCRIPT, C#, and a little python/java
@@3dblingcmg762 first of all "only" knowing those languages are very good and will probably give you a job already and second of all i don't think companies really care about how fast you write except you have to atleast be able to finish small projects within 1 hour. So if my predictions are correct you can basically get a job depending on how good your knowledge within HTML, CSS, Javascript and c#, and if you get a job within those languages a tip is just continue learning python / java or any other language that you want to learn. (I am no expert nor do i have a job but i think my information is correct and never stop believing in yourself) (and sorry if i made some grammar mistakes or typing mistakes)

@@maskedman8368 its intriguing. He wants to understand
Imagine if this guy just had a second monitor.
Frrrrr
No because turning his head and moving the cursor takes time
Alt tabbing is faster than two monitors. It loses in everything else, except speed. If you have a project youre working on for 2 weeks, then 2 screens (or more) is much better. But if youre literally in a speed coding competition, alt tabbing is a winner.
alt + tab, is faster than looking at a second monitor
Luckily he doesn't otherwise he would break his neck going back ans forth
I’ve been programming for over a decade and man, I don’t think I’ll ever reach this level of awesomeness.
I thought all programmers ever do is just copy some lines and then when there’s an error , google what the error means and then copy paste the solution to the error , isnt it ? This Asian kid seems like he’s probably that one dude that solves every programmers’ problems and error codes in the forum
There's 1 minute left of video and I still cannot process what he has done, amazing.
Give this guy a second monitor, he could have finished earlier.
he more than deserves it
True
For some people it is just more convenient working on one. For me as well. On my first job I had two monitors and noticed how I hated to move my neck. Also I didn't want to get distracted from the light of the second monitor. Alt+tab gang forever
for me its easier to just use alt tab because its fast then lookin to the side if my setup

The SPEEEEEEEED, both reading and typing, like even typing normal words i don't get close to his speed, also what i find interesting is how he just codes mostly top to bottom, when i'm programming i'm jumping all over the place the entire time, very impressive over all
This man went through something that made my vision blurry after and i might need glasses and has the audacity to say "i thought it would be harder" there are some smart people in this world

He's the guy answering all your questions in Chat GPT
Man, I feel like coding is your native language.
Yeah, im pretty jealous he can type this without googling
@@znspyder cmon man, I don't know why would someone need to google how to do for or while cycles, since that is the most basic thing in any programming language. Not to be ignorant, I can see why someone, who hasn't seen a programming language can think that. Awesome, on the other hand is that he could solve these problems under 20 mins.
This is unbelievably impressive, however it's important to point out that William (and other's who solve algorithms in competitions like this) know exactly which solution to apply to each problem. For example at 2:50 you hear him say "this looks like a Knapsack problem". Knowing what the problem is means he can much more quickly use an "out of the box" structure to solve that problem - for example Knapsack problem's can be solved using Dynamic Programming.
Knowing that you need to use Dynamic Programming to solve a problem means you can instantly begin structuring your solution before you even finish reading the problem (as William does).
To outsiders it will look like he is just coming up with a solution there and then. Although this is partly true, the basis to his solutions are from understanding what the problem is asking - to dumb it right down, he sees that the hole is a square, knows he needs to construct a square peg and knows how to structure this quickly.
Not to take anything away from William, again this is unbelievably impressive. But dont feel like you cant ever be this good or understand problems like this - you can, you just need to learn how to see what area of programming the problem is targeting and then learn which solution to apply to that area :)
Very well said!
thanks for the explanation!
