I doubt to be honest, you can be great competitive programmer but lack knowledge from computer science
@@dscmtr686 I agree.
I have like 6 months in coding FS MERN stack, I just watched the first 4 min, saw how he solved the first problem,saw how he outputted his entry directly from the terminal, closed my laptop, crawled in a fetus position on the floor and started to cry.
😂😂💀

Been programming for nearly 5 years. No where near this speed. It's insane.
My brain was having trouble processing what he was doing from the very first second this video started 😂😂
its c++ code at beginning
I learned something from this program which will help me a lot
Thanks
It took me 7 minutes to read and understand the problem!!! He literally started coding after one single minute!!!
9 year old me using inspect element like a boss not knowing what’s going on:

it's a joke @@youbro1144
You Bro nooo I meant back when I was 9 years old
i used to hack facebook game using inspect element back in 2013 😂
Yo that makes me think of a funny joke i did at school around that age. Make a BATCH script that would create a %r%r%r folder and place it on your desktop. With a echo print saying “please wait while the game loads”. Funny man i was...
My favorite line:
“bool ok = true;”
I live by those words
I don't get what you mean, isn't that a very common line..
Bool means anus in indonesia
Mhm Very Nice why?
@@KoepenickDrums I’ve never coded once in my life and idk why I watched the video, but knowing that the bool is in fact ok, it brings me peace
Seeing this make my confidence in coding drop to the ground, knowing i never be able to solve and code at this speed and quality. For me 1 hour is needed just to understand one problem...
don't say this. be grateful for what you have and do not compare yourself to others. compare yourself to the version you were yesterday and strive to be better today. if it really is a goal of yours to get better, just work hard and don't get caught up in the bs that is in mans mind sometimes. do not expect instant changes, but change chings up, if you're not making as much progress as you want after some time, so you'll eventuall find your personal most efficient way. just do this, learn to accept and maybe even enjoy the ride and just like i said be grateful for what you already have, whatever it may be and I guarantee you will see improvement over time.
Stay focused 💪
Congratulations!!

You had to say "I'm in"

Estoy dentro
Your a wizard larry.
I can understand some of the code because I learned C up to a semi-advanced level for a year, but, the speed at which you process the information and come up with the conditions/logic is astounding. One day I wish to think and write code this efficiently.
Maxemore it probably comes from many hours of practise and work. Maybe also from a preexisting solid fundamental understanding of math and logic. I’d also love to be able to be like him one day, but i don’t think i can without going back and relearning these fundamentals thoroughly
if ur smart enough and practise hard for 2-3 years with competitive programming. I believe u can be like him. Hard work on the right area pays off
Learning the language is easy, the problem is how you construct the codes to make it work as expected. I realized that as soon as I understood the basics. Damn, I wish I am as smart as the guy in the video
@@alpt1980 it's like mathematics
With rouhack on your side you have the power over any device, or social account no matter how strong their security is, the hacker on iG is definitely the best

Im just having alot of fun watching this genius guy
you solve the problem faster than i read the task.
This is so true and frustrating for a beginer software enginner like me. This make me question my life decision of becoming software engineer.

Good work buddy keep it up
Hi Errichto, just wondering what keyboard were you using in the video? Thanks
He’s very clever. I tried to follow along and pause and think how to solve it and then resume and see what he did. He always has something more simple, faster, and less lines of code. Very impressed
👆he’ll get you immediate access to any social media account you want, he’s an expert in this!
I'll be honest, I think I would have understood a random video of a Turkish guy talking for 30mins more than what I just saw. But your video still intrigued me nonetheless!
... and you type in code faster than I type in english
Well, fast coding (especially with great IDE) is easier than type in english or in any other language.
Yeah, he is Amazing.
Lol had to put the Turkish in there
Wow I am Turkish and this is racist lol
No More Name it’s not racist, şaka yaptı
Wow I want to learn how you do that. That's amazing ❣️
I just love the logic behind the coding ... sadly that's the smallest part of the work :(
I shouldn't have ruined my life playing games...
Fair
Success its not always money and recognition
r u 80?
me rn 😔
Same
I just realised this looks like the same stuff I type when I rage quit and smash my keyboard after losing in a game.
Underrated comment
Made My day! Hahahaha xD
maybe your true self is a real hacker who knows
quality content bro. niceeeeee
I didn't understand a single word but watching him coding at 2x is satisfaction and fun😅
You are insane bro. I would read the problems and understand what they were asking but the sheer speed with which u come up with the logic to solve the problems in code is unbelievable one day I hope to be like you Fr Fr
As a yasuo main, the only code i understood was, int (me)
🤣🤣🤣🤣 while {me < 10; ++me}

Great comment
I dont get it
hi Errichto Good job ! , how did you manage to be excellent at coding like that ? i need advices from you
TIA !

Everybody talking about how good he has done, while I am still amazed by his terminal knowledge
I've just started using a LINUX based system as a part of my job profile and he's doing pretty basical terminal stuff. Not hating on him but anything about terminal for folks like us who grew up GUI looks geeky!
Most of what he wrote was
Ls
Cat
Wc
Grep
And using piping and directing
If you use the terminal at all, these are essential to know
He is very very smart, but the bash commands were standard for every user
I was more amazed at this pace of actual coding and creation. Damn
Terminal is insanely hard to learn and even harder to actually utilize, props to him
@@okie9025 terminal is not insanly hard to use, dont scare people away like that.
Let me give a quick tutorial to using it
open terminal and type "ls" now you can see files and folders. Type "cd Downloads" now you are in downloads folder. Say you have a file called foo.txt and you want to see whats in it: type "cat foo.txt" how many lines does foo.txt have? wc -l foo.txt. (those dashes are called flag arguments, -l means line -w would be words etc..)how about moving foo.txt to a new folder? mv foo.txt newfolder/
How about copying a file? cp foo.txt newfoo.txt
How about deleting it? rm newfoo.txt
Renaming? mv foo.txt foorename.txt
How about running a program (lets say vim) on the text file? vim foorename.txt
Its that easy!
Me: step 1 , type without mistakes - FAIL.
Also me: There are trees that fall left or right. hmmm... Trying to imagine the scene.
Errichto : and the results match, And I upload the file.
Thank you 🙏
Thanks!!
You solving this so easy, makes me feel stupid and I'm software engineer
Se here lol
Im a systems admin and I have no idea how he is doing this soo fast
the best I could manage to understand is that, on first 3 problems, they were fully mathematical, not really programming dependant in general~.... you know... I think...
Nico Bego its because he didn’t waste his time going to school for a degree
Second place 🐸
Him: *video above"
People in comment: print("hello world")
Me: I'm a hacker
you made a heading.... good job?
Baramoo congratulations, you got the joke!

Forgot the color green tho
Echo "Hello world "
You are great sir !!
Me: actually kinda understanding what he is doing
Also me: knowing i would never figure that out myself.

Int main(void) {
printf("pls send help");
return 0;
}

Fajnie że w Polsce mamy takich programistów :D
Everyone be talking about how good he is at programming but all I want to know if how tf he is typing so fast
literally
programming is repetitive imo, so over time you'll get used to the muscle movements to type things like for loops and such. over years of programming, you'd also naturally get faster as you type so much in programming
@@avocadostuff2881 I second this. Typing while looking at the screen is not a skill of mine. The repetition of code makes this possible for me (only when coding) however.
Have you seen those people who sit at court room and type everything it been said. It takes practice you can’t be good at something if you don’t practice
For a second i went and checked my speed to verify if by mistake i have set it to 1.5x😂
*AFTER READING PROBLEM*
Me: How do I solve this problem?
Errichto: contraints are too low.
🤣 true!!
after reading the problem i take a break for 15 mins and then i be like "aaah, shitt!! Here we go again"
If you look closely he always looks down after every question. My guess is that he already solved all the problems beforehand and just print out the code and copy it.

Unfortunately only about 10% of a programmers job is like this. Otherwise stupid meetings and office politics about tech stack.

Watching this man writing codes faster than I write my primary language be like: Why do I even breathe?
Perfect and legit hacks service with this pro #andrewhack35 on Instagram he helped me to recover my account
code is meant to be written like this. It’s a tool to express logic and conditions with a specific set of keywords to use, that’s why it’s faster. Try making a statement linguistically. You can probably convey the same meaning using a million different combinations of words, grammar, sentence structure, and expressions, yet in code there is only a certain number of combinations to express a certain statement. Also, programming and language are fundamentally different. Code is basically a bunch of logic statements, while language is a tool used to express emotions, experiences, ideas, etc. Lastly, code is optimized to hold the most amount of information in the least amount of characters written, while language literally doesn’t care how much you write and in some fields it is encouraged to be verbose in your writing. Don’t worry, it’s normal.
