Holy shit! I just watched you solve the second problem and already learnt 2 new things - 1. Using dx and dy as against using modulo to figure out the directions. 2. Using vector as a queue in C++ It’s these small things that make a difference in competitive programming I guess.
Thanks for sharing your solutions. It’s great to see you participating in LC contests and helping folks out. Hoping you will keep up the good work by participating in future contests.
Couldn't solve the fourth problem for straight two months. Didn't even occur to me to iterate through all possible starting time values. Also, amazing coding speed.
@@zdravkobeykov it was a similar problem from ICPC drills. The only difference was that routes cost various amounts of currency, and you had to find the quickest route that was within the given budget.
I graduated as a computer engineer and i've only done a few problems in the past 4 years because i was forced to focus on different disciplines in my university. How long will it take to get me back in shape. btw im new to this channel and my competitive programming skill is potato.
I think all people who practices more get to solve problems faster..... That why I always see frequent names in the top 20 list..... It's really that recognizing patterns in the problem fast......! 👍🏻
Python TLE for the first problem with the exact same code lol, had to change mine to precalculate the possible c**2 values in a set instead (not before losing 5min from penalty though). Also, q3 was so hard for me to figure out during the contest.
@@kameshkotwani On codeforces, yes. But they tune the time limits relative to the langauge on leetcode (not always perfectly). Generally any solution with optimal runtime complexity will pass in any language on the site.
Dont you find it annoying to use mouse while typing. What if we could control without mouse. Mouse is great but when you are too much into typing handling mouse breaks your flow.
Why you do so much competitive coding the things you know and how your brains works is more more more more than enough for the best best best company in the worlld 😂😂
Anyone please help me 🥰🥰🥰🥰 If I want to be expert at c++ and participate in large tournaments what is the full tree or what should I learn from basics to expert and how long does it takes for me and thanks 🥰🥰🥰🥰

lmao bruh..
Errichto is motivating me to start the weekly LC contest now haha

How 2 months when it's 3 weeks old?

Loved this screencast
My python solution for Q4 is exactly same algorithm as you, however, it gets TLE.
Nie mogłam uwierzyć, że jesteś z Polski!
Bardzo ciekawe wywiady, rozwiązania zadań algorytmicznych
Podziwiam! :)
I really love your coding style.
Bylo blisko...i tak jestes najlepszy ;))

🧸 love keyboard cam
god gifted him with extraordinary intelligence but forgot to add the portion for remembering youtube passwords.
He already said in a stream that after a stream on the second channel he is taking break in this month.
@@limakbear7029 ohh I didn’t know that
Is CP book Competitive Programming 4 by Steven Halim any help?
which keyboard is that and what is you typing speed??
100+ WPM, logitech ultrax premium (an old keyboard, not produced anymore)
@@Errichto very fast
@@ankitmajee yep, it is very fast, because typing while thinking
Hey Errichto, do you only do training for people in high level competitions or do you train lower level competitors also?
@Errichto, can Q2 be solved recursively ?
Please make a video on topological sort and also on TRIE
thanks for the solution , it was very great :D
Youre a god bro i saw your rating on leetcode please make that kind of video
Thank you!
Where r u sir? Can't see your video for so long
anh there codeforce will have a contest tonight , can you tell me when will the soltuion of the contest upload ?
Thank you friend ☺️
Love your videos.. Keep going. Btw would u like to go to FAANG?
Read his FAQ
He's typing faster than I can think
In just 16 min😵😵
Hi Eric , love these short vids. What keyboard are you using? Nvm saw your answer below
You can read his FAQ
Where can i find that faq i really need the name of that keyboard @limak bear
@@limakbear7029 where can i find his faq i really need the name that keyboard
@@kurdicodes9167 yeah where @@
@Errichto why have you not posted any videos recently

That's why c++ and java are preferred, Python is slow, for exact same logic it takes considerable amount to execute.

Best book for recursion ??
You really love coming in second place, Great job though
how much time did you spend a day solving problems to be a red coder?
Great video
In which company you work??
Which distro??
This is so satisfying :)
ruclips.net/video/UlJi2U6yYmQ/видео.html for the august leetcode challenge, you can follow this
bro, do you have method about recover winRAR zip files password ?
How you compile the code
question 3 sounds like minimax
Dude, who finish first??
Loved this
Are you on instagram ?
In the second question, is there any reason why you used vector of pairs instead of a queue ?
Errichto my idol!!!!!!!!!!!!
Legend ❤
nice errichto
Plz make a video about IOI. Plz sir❤️.

Hey man.. you can always change your password if you have forgotten it. If u need a tutorial ping me. But please upload
Na szczęście w pracy nie potrzeba takich problemów rozwiązywać.
except programming, what have you learned to solve problems that fast ?
Wizard
u use linux?
Yes, he is comfortable using Linux (Ubuntu) he also use Windows, because it's convenient to stream.
Anybody had attend errichto classes?
No entiendo que dices xd, pero me gustan tus videos, nuevo sub bro :D
es ingles
i ask myself how are you so good at programming with only less than 2k problems in codeforces
He did a lot of Math problems and that too for years
He solved on different platforms duh, TCO was pretty big pre-2018
U'r awesome🌸
I am 17 years old.I want be good at competitive programming. Please give me some suggestions.
Solve problems, you can watch his "how to start with competitive programming" video.
High IQ
What are you meaning by high iq
If you know hindi i can recommend you a good channel to start with
@@sabbirhasan3372 and once you start never stop. atleast do one ques even if you are very busy. Being consistent is the key.
After so long first comment love from love ur videos please do make regularly
اكو عرب بالطيارة ؟
Ｕ R SO SMART!!!
Not even looking at the keyboard
0:02 3 hands???????
RIP?
eyy nvm hes on twitch
Imagine getting a reply from Erricto 🙂
Please, the way to reverse engineer and hack android apk!
I love you brother
