Hi Errichto! Will it be possible for you to make the competitive programming videos into a full tutorial series? From beginner to advanced?

[@connectgfv6775]

I can Edit for you but I know that you do it for yourself and the joy of completing but pls If you ever think you need someone for editing just consider me

Hey Erric ! Please make a video specifically on CODE JAM and tell us about your journey of becoming such a good programmer ! Thank you !

[@at6727]

you're quite generous bro! you'll reach heights

[@Gold_fi]

Thank you for teaching how to go about Competitive prog..pls keep it up. I've followed your channel since you are under 5k followers. Pls continue to do this and keep safe. Pls how long does it take to prepare for competition?

[@Errichto]

You can prepare for 1 hour, you can prepare 20 years ;p if you're asking about some warm-up before a contest, 20 seconds to cool down is enough

[@MCBarracudo]

Świetne filmiki ! Na dzień dzisiejszy dla mnie competetive programming to abstrakcja , ale lubię sobie od czasu do czasu popisać jakieś proste algorytmy. Wszystkiego dobrego, samych 1 miejsc na zawodach życzę :)

[@sumitkumarsingh6037]

watched your dynamic programming videos...they were excellent. please continue the series

[@namaasliku8642]

I started to practice problem-solving inspired by watching your video! It's more about filling free time though rather than wanting to compete. Now it's just whether I can stick with it or not, it's very frustrating when the question marked easy and I have no idea how to solve it. haha. hoping one day I could solve problems marked hard easily.

[@kirdiekirdie]

My big goal is to get the Google Code jam T-Shirt once but I never got further than round 2, this is really hard for me even though I studied computer science for many years and have been doing the code jam for 5 years. Amazing that you got hundreds of those t shirts 😁

[@AnthonyMcqueen1987]

Competitive programmers dont do It for the money like he said "Its not crazy money but nice". They do for the love of the sport and to solve some of the toughest problems. Ultimately become the best in the world.

If there are multiple trains for the same cost the train with lesser connections must be ordered higher.

[@christianpaoliello2826]

Great content. I'd like to ask a question. When you participate in online competitions do you use custom libraries which you built beforehand to solve common subproblems? Can you do such a thing in onsite competitions?

[@nopecharon]

Nope

[@angiras07]

After solving some implementation problems i want to learn algorithns so should start from divide and conquer or the important ones like dp and from where shoild i learn these

[@Errichto]

solve problems and read editorials, you will encounter techniques you need

[@ionuttiplea4666]

You probably want to learn data structures, they are very handy. After that you may want to focus just like Errichto said on solving problems. While doing so you will encounter the algorithms like Divide and Conquer, Backtracking, Quick sort and so on. You might also want to focus a little on the efficiency of each algorithm you do or you learn so that you might use the given data constraints in your favor, for example guessing what type of algorithm the optimal solution would be and see if you get an idea

Same as advice for anybody else: practice. The main issue is that it's hard to find so much free time when you are older.
