@@julianferres It was actually a very basic problem, checking our understanding of modular arithmetic's. We could solve it with in a six lines brute force over 12 states for 3! hands positions, without any special algorithms. Thought that "tick"-coordinates and 1/12 really complicated the whole thing :(
@@harisasif2639 Not always in my opinion. At least for me there are problems where I find the main difficulty lies in the implementation (usually that are constructive problems, interactive problems, problems that require backtracking or some weird data structures ...). Even implementing some conceptually rather simple algorithm like binary search or quick sort can require a bit of care (I have seen many people struggle a lot with those indices)
@@Errichto yahh exactly and I think second one was also not a round 1 problem ... Anyways... congratulations to you , I have learnt a lot from your videos 🙏
Direct addition of seconds and then dividing it by sixty twice will give the amount of time obtained in the clock and this will also give th exact position of the respective hands of the clock
I was wondering something - at around 48:20 you have dp[0][0][0][0] coming in at over 19.07..., but by the time you submit around 56:30 it is down to 18.08..., which is less than 98% of what's theoretically desired. Do you know why it works regardless?
do you reply to messages if yes can you tell me how long did it take for you to try and figure out solution of a problem of rating 1200 without any help please tell?
Solve all Easy on leetcode, so you could do 4 in a row in less than half an hour. Only 4 every day. In 6 months you'll be ready to take part in contest and do all of Middle. Then Hard. And while learning read Laaksonen guide to competitive programming, for example.
I had brain haemorrhage reading problem A. Too much of innovation, eh? Problem c was cool. I am never too comfortable with problems which are interactive + probability type. Still, it was fun.
"What a stupid problem" XD That made my day!
Time ?
@@uploder247 0:37 , did you even begin watching the video or you always go to the comments before watching? xD
Mine too
lmao it made my night
The questions in the contest arenot enough for him.he asks himself even more. Lol
As a beginner seeing this
Me: *What am I doing in my life?*
Don't understand anything, but yet support him.
If the problem was unpleasant to solve, I wonder how unpleasant it was to create.
Just want to share this ideal with you guys any time you got issues with your social media account contact codedhacker999
Yea but the creators didnt have a ticking clock in front of their face
I spent 20 mins just scrolling up and down on the first question...🤕
It was 9.30PM here, I opened the contest link, read the first problem, said "nah" and went to sleep 😂
lol i'm laughing first problem was confusing af hahaha
Relatable
same
Same
I just stare at the question 1 until competition ended
I've already watched the whole video but I am coming back again and again for 0:38
It was indeed a stupid problem jaja 😅

Yet again, I have no idea what I am looking at.
But you still do it
It was a face clock, I think.
Congrats Errichto for score of 100. 🎉🎉And yeah first was really a stupid wasn't able to solve it 😞
Same. Have u solved second test set of second task?
today's round was just too depressing. I mean the difference between the difficulty of 1A and 1B lol
I wouldn't even consider round 1B a programming competition. It was a pure math competition! 95% figuring out the math, 5% programming ...
was A much harder than B or the other way around?
@@zacharychao2377 B was a lot harder in my opinion
@@christianpaul3651 alas programming is always the easy part

24:20, In Subtransmutation, how fast he comes up that impossible case depends on gcd of a,b? What was the intuition? Anyone?
I like the fact that I am not the only one thinking whoever wrote first problem should be fired
I have no idea what he's doing or how to read it but I'm blown away. Entirely different language
You are gonna sail through Round 1 and 2, good luck for round 3. Last year was a heart break.
Congratulations Errichto
what the heck was this round .... I wasn't able to solve a single test case 😭😭😭
The first problem was just so unpleasant...
@@Errichto yahh exactly and I think second one was also not a round 1 problem ...
Anyways... congratulations to you , I have learnt a lot from your videos 🙏
Congrats Errichto, I am also qualified for round 2.
Your speed to write a 4d dp was just a beast...it would take me an hour after the transition is given...
What would the difficulty of these problem be in codeforces? i find them hard af
I wasnt able to do a single one 😭
True
In my opinion A&B are around codeforces Div2C. Somewhat like ~1700 maybe.
I totally don't understand what's going in your code, but your place is stunning! Brawo, Kamil :D
I actually spent whole time fighting with this problem and I guess missed that very last check for "H
and here I thought that the correct way to read a problem was from the beginning to the end...
dp[current challenge ] = dp[past challenge-1] + errichto's superpowers 🙏🏻 God
Direct addition of seconds and then dividing it by sixty twice will give the amount of time obtained in the clock and this will also give th exact position of the respective hands of the clock
Congrats Errichto ❤️🎉🎊
Very cool. I feel like an ape watching you do a 4 dimensional dp problem. I can't believe I have a google interview tomorrow.
"What a stupid problem."
LMAO XD
Watching this makes me feel like such a noob I am😥😂
Finally after so long. Missed you a lot Kamil!
What a stupid problem 0:38😂
I was reading along with him... I also tot "what a stupid problem" when he did
As soon as I learned the C language this video came to my recommendation and u know what happened after...
Is it helping to code using C ? I thought that competitive programming needs a "more dynamic " language , NO ?
Hey Errichito.
Do you participate in ipsc contests aswell (Internet Problem Solving Contest)!?
I screwed up this round..ㅠㅠ
Hey Brother, could you help me something? I exposed the Ransomware virus, so my files encrypted .wrui, can you fix it? with the state of online ID
how to get the cursor out of curly brackets in code blocks if somebody knows please tell me
Maybe a stupid question... but which ide are you using?
Not a stupid - you can find video about his setup ruclips.net/video/xAeiXy8-9Y8/видео.html&start_radio=1&t=0
why errichto uses scanf instead of cin
is there any reason
i am new to cp
cin is in C++ and scanf is in C
@@thel0negh0st scanf is also in c++
And he is using c++
gratuluję ogarniania tego jakkolwiek! :D
ja nie potrafię w najmniejszym procencie tego zrobić, do dzisiejszej rundy nawet nie mam co się przykładać

good job errichto!
do you reply to messages if yes can you tell me how long did it take for you to try and figure out solution of a problem of rating 1200 without any help please tell?
Great video 💛💛 thanks 💛
How many of you noticed 0:37😅..me all the times when solving codes!!
Sir we want setup video.
can anybody tell me if he uses his left hand or not?
Hi whats sides do you prefer to learn c++
how was he able to read the problem descriptions so fast? Is the structure always the same, so that you can skip some parts?
Bro You are amazing 🔥👍
Hello Errichto. There is the codingame contest spring challenge on May 06 ,I hope u will participate and upload video
I hope you’re getting paid the big dollars putting in these efforts
I agree!!!! The first problem is literally "annoying"🥴
I just started learning programming (basics) , how can i reach at that level ??
Years of programming and you be good enough to solve problems

Round A was easier in my opinion

Didn't know Declan Rice was a programmer 😅
Good job 👏🏻
dobry jesteś gościu, też bym tak chciał umiećxD
You are insane dude o_O
You are awesome ❤️❤️
Your the best 👍
to be completely honest it was a stupid problem.
what os do you use

That"s great.
You should definitely use vim. It is non negotiable

It's Ubuntu without any changes.
