Bro, I also participated in this google kick start round A but in my first 6 min i am only able to solve the 1st problem and other problem take more time ...... Bro your speed is amaze..... Can you give me some tips and tricks.
William solved an entire question in less than 2 minutes. I wasn't even able to read the first sentence of the question. I am graduating with a CE degree in less than 6 months, and it is scary to think that people like this guy exist. Good job man
He practiced >10 hours a day for this stuff. After ruthless repetition you understand the patterns these questions have and you can find the solution to a problem in literally seconds You can do anything anon. You are that guy.
Who is "the guy?" your claim isnt supported by enough evidence and is way too vague to be taken seriously. I have decided to close this post. Without enough context there's not much we can do.
nah, stackoverflow is mainly for web devs and "real" programming ,this is competitive programming its like math exercices but with coding you dont even need stackoverflow its logic and problem solving more than any thing
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.

You guys are saying the impressive part is how fast he came up with a solution. I didn't even read the first sentence of the problem and he already started writing.
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.

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 :)
@@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.
The only thing, that gives me hope, is the fact, that he is the best of all other contestants. Imagine, if he would be not first but somewhere around 100th
@Abaddon Fail Пунктуация в английском вообще довольно спорная вещь. Она, безусловно, существует в академической науке, в литературном языке, но на практике она или вообще не используется или используется крайне интуитивно. Даже в лонгридах на всяких реддитах и прочих соц.платформах люди с нативным английским частенько пренебрегают правилами. На самом деле одна из фишечек живого языка.
@@georgevoknerech228 yeah don’t worry about punctuating things too correctly as long as it’s all readable and understandable but only if you are online. Anything formal you need to punctuate perfectly.
@@georgevoknerech228 That is false for anyone who is in college, while in Russia it is taught in school. English has all the same punct. rules as Russian, but there is also an Oxford comma. So, complex sentences need to have a comma, same about but, but not one and, but needed for many and. Also same about :, ; and --.
This is what competitive programming (aka preparing for cs olympiads) looks like. He got gold (and first place) in 2020 and silver in 2019 in the IOI (international olympiad in informatics), aka he's a beast. These problems were... incomprehensibly easy for him, compared to IOI problems. I only got to the national stages in my country and went to some smaller international competitions and I still had to work hard. I can't even imagine what he went through to become like this. This guy spent hours and hours each day to become this good, and he deserves a lot of respect.
Out of interest, How do you find these competitions? I'm a current lower year Sixth Former and I want to do comsci in university. That being said, I believe these competitions will act as an opportunity for and towards my education. Thank you

For me it’s not the programming itself that’s crazy (even though it’s still on another world of skill) it’s the fact he just completely understands the paragraphs of problems in not even 5 seconds
How do you even waste 17 minutes figuring out if you're currently using a dark theme? You must be blind or something, then. In which case using certain theme wouldn't matter much.
@@SouradeepSD yeah, but it wouldn't be faster. he is basically telling the best in the world what to do in what he is the best in the world in. there is no one faster in competitive programming than Lin.
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
The problems are pretty easy you'll get used to logical structuring of problems as time goes on. The thing is in a commericial environment these types of developers are always a pain to work with. Remember at work readability is > everything else for 99% of the stuff you would work on as a software engineer.
@@badderborroda4972 it's also worth to mention that writing long variable names especially more than once it's just a waste of time when you're running against a clock. he always uses the same constants and function names across all challenges so that he can do stuff in a mnemonic way. here the focus isn't about readability but getting the implementation right.
@@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.

@@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.

The goal of optimizing code is to balance the smallest runtime with the smallest amount of memory used, although these days run time is much more important than memory usage (because computers today can work with so much more memory through larger ram / cache sizes).
I remember seeing this video in my first year of college 4 years ago when i was still learning how to code and thought i was just dumb, luckily i didnt give up and kept moving. Dont use videos like this to guage yourself, have a motivation for coding and no, you probably wont make 500k by just watching free code camp tutorials, actually build things you like, that is what worked for me.

when I first start coding in C++, I use return 1 at the end of my main function. So the evaluator bot at the competition I was in keeps telling me that my code has errors or wasn't able to run, even for my hello world program. It wasn't until after the competition that I asked my friend that he told me that any returns other than 0 in C++ mean error. So, that is the story of me debugging my 1 line Hello World in C++ for 2 hours.

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!

@Abaddon Fail мб, но пунктуация в англ особо не нужна
@Abaddon Fail Пунктуация в английском вообще довольно спорная вещь. Она, безусловно, существует в академической науке, в литературном языке, но на практике она или вообще не используется или используется крайне интуитивно. Даже в лонгридах на всяких реддитах и прочих соц.платформах люди с нативным английским частенько пренебрегают правилами. На самом деле одна из фишечек живого языка.
@@georgevoknerech228 yeah don’t worry about punctuating things too correctly as long as it’s all readable and understandable but only if you are online. Anything formal you need to punctuate perfectly.
@@georgevoknerech228 That is false for anyone who is in college, while in Russia it is taught in school. English has all the same punct. rules as Russian, but there is also an Oxford comma. So, complex sentences need to have a comma, same about but, but not one and, but needed for many and. Also same about :, ; and --.

I only got to the national stages in my country and went to some smaller international competitions and I still had to work hard. I can't even imagine what he went through to become like this.

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)

The goal of optimizing code is to balance the smallest runtime with the smallest amount of memory used, although these days run time is much more important than memory usage (because computers today can work with so much more memory through larger ram / cache sizes).
