- I'm again joined by David (@SecondThread) to discuss an interesting algorithmic problem. It's Railroad Renovations from Facebook Hacker Cup Round 3. Watch the other video we made, Robot Cleaning • Algo Talk with Erricht...

Errichto and SecondThread are on fire and the community is benefiting from their collabs
Hello Errichto can you create some playlists for DS and algorithm because I followed you for two days and I love your way to explain.
i do not under stand any of this videos in this channel i just love his face and his quickly typing
I just came here, and i have no idea what are they talking about 🤣
Thank you guys for this video !
please make more videos like this ..... it really helps a lot
I watched your other videos and noticed you used vim extensively and seem to know all the keyword combos to get the best use of it. Please do a small tutorial on how to use vim or nano
What keyboard are you using Errichto?
Please make a couple of educational videos on DFS and BFS just like you have for dynamic programming.
You are talented man, cooollll, keeppp ittt uppp 🥰👍🥰👍🥰🥰👌🙏😁👌
These colabs are great
Are you actually using a mouse while drawing the stuff on the board? Cz it seems fairly neat and easy.
Also, love this sort of two way discussion and th exchange of various ideas at different stages.
He is using a digital pen bro.
Good job!
Hello dude can make a video on what changes have you made in geany....please
Like how did you overcome the problem of underscore, how to make a template code every time.... like that make a video please
Hey I want to ask..
If you are using one c++ template.
And every other coders use the same template...
Than in contest would it be considered to plagiarism...
Coz almost 40% code is same as others (due to this template )
I'm no expert but because time of submitting solution is measured it actually will be hard to cheat and if several people use the same algo template this is totally OK if you can see that the rest of the implementation is authentic
@@KoepenickDrums but in lot of coding exams.. let it be codechef or Amazon..
Lot of candidates face this plagiarism issue.. you may find in those issue in Google..
There codes are correct still they unable to proceed further..
This tool plagiarism detector.. has take down lot of candidates who use template..
But for international level competition.. they are just fine..
@@marveltv5341 That's why the fastest win :) or maybe problems should be original enough so you can't use existing templates, but I guess that's too much to ask for as there are a limited amount of algos
Good Morning Sir,
Sir, I want to say that can you make a video on selected topics :
1.> complete d.p.
2.> some important technique mostly used in coding interview/contest
3.> the last one how to recognize the question that it is from binary search, D.P. or simple array.
I hope you will to all kind of people like me !!!!!!!!!!!!!!!!!!!!
Discord link pls, the one in the banner is invalid

@Errichto : please N Queen backtracking problem !
anybody friends can help me out, i heard va panel monitor is much better for coding for having extremely srgb, text r much sharper, compare to same price ($230) ips panel monitor , what u think guys ? is it better asus vg249q for reading text sharp ? or which one will be better in this budget , i want monitor for reading so much pdf , and practicing c++ , java etc.
Can u please provide solution and explanation for the below :
Write a program to find Largest 4 digits Prime Number whose Sum of Digits is also Prime.
1.Prime Number is any number that is divisible only by 1 and itself. Examples are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31,........
2.Sum of Digits means sum of all the digits in that number. Example is number is 1234 then the sum of digits is 1+2+3+4=10
How do you learn programming? What is the first step?

Hi , bro
Sorry for off topic , but I see that u r one of the most popular hackers in CZcams. There’s a problem which is killing me and a lot of people around the world - input lag. Massive and huge input lag , have you ever faced with that theme?
If u can help or explain what to do to get rid of it - create a video. Best wishes , bye!
Yooo bro give me some tips for fb ads algorithm pixel 😂
can u make .e a executor for a game called roblox
siema jestes polakiem? :)
You're skipping some parts of the problem or the explanation was not coherent because there were some points where I lost track. Maybe it's good to read the initial problem before watching the video but I guess it'd be great if that wasn't necessary
Carl H 2.0?!
Why wasn't SecondThread allowed to participate???
As he said he was a tester to that question. Which means he knew that it was going to appear in the contest.
Maybe he works for facebook?
@@amritm5806 yupp,.got it :)
second (thread)
Legend says Errichto considered pinning my comment.
0th?
hi i was impressed woth ur intelligence and ur work... I would like to ask CAN U MAKE SOME MOD FOR A ONLINE GAME? LIKE " Toram Online" can u please answer 🙏🙏🙏
william better than you bro
I am sorry but these questions are all trivial mathematics and intro to algorithms type of material taught at any decent undergrad peogram. Why is this competition significant? Sorry. I don't understand the significance of this. Is it just for fun?
