My practice methods
By galen_colin, 3 years ago, In English

Oh no, another good youtuber lost to the algorithm...

And you'd be right. So on my journey to become a sellout, I've put out a video describing, in brief, the way I would find problems to practice on. It's designed as a short overview, with a more detailed description to follow. Video is here, just under 90 seconds in length.

Note that everything is my opinion — maybe you have other experiences and/or other opinions, and that's fine, do what works for you.

You should stop being guilty for these titles or the type of videos. As long as the content promised is in there, it's not clickbait, but "LegitBait". more here

galen_colin Thanks a lot . Could You also please suggest some gym or ladders to solve the problems topic wise.

My question is should we go with topic wise problem solving or should we follow some ladders of problem having same difficulty level?

Could you suggest some good ladders or gym to practice. Thanks

    Nothing will work for you. You know why? Because I have been seeing you comment stupid shit on youtube and codeforces for more than a year. How many problems you have solved on codeforces? 125! I want to say a lot more but cf will ban me.

    USACO Guide is the best resource to solve topicwise.

I really like the information dense video style of narrating the idea and having text with additional details.

It was only 90 seconds long, but it left me satisfied and smiling.

So one element of Youtube Algorithm is Click Through Rate , but watch-time is also a great one ,In your channel you post 2 hour long videos and people probably watch it all till the end because of the solutions (at least I do most of the time ) then why haven't your channel boomed yet ? YT should recommend your channel to everyone due to the watch-time,,, & also I also want to start a channel documenting my learning journey any tips on YT and on how to git gud at coding ?

    Average watch time per person for any given screencast is only 4-6 minutes, which seems to imply that many of the views aren't really interested in seeing solutions or skip around a lot. So the watch time is a lot less than you may expect. That, combined with the fact that a screencast for a contest is normally not that interesting to anyone outside of that platform (except for a few exceptions), and a few other hypothetical factors that I can't confirm to be true or not, means that an average screencast won't be pushed out that far.

    And yeah, watch time is definitely important, this particular blog's video likely did relatively subpar because of the short length that didn't get offset enough by more views.

    I'm totally willing to spew out my thoughts on youtube, just shoot me a dm on discord or something.

      I'm yet to find any realistic screencast done by a grandmaster level contestant showing their participation in a CF global or Div1+2 round. Demonstrating how they go through multiple easiest problems in just a few minutes. I would like to see how the time is distributed between reading problem statements, typing code (or maybe copy/pasting some templates?), testing it (or maybe skipping this stage entirely to save time?) and submitting the solutions.

      None of the existing screencasts that I tried to watch offered anything useful. Though I haven't checked many of them and may have missed something. Do you have a good recommendation?

        I personally don't screencast rated rounds except for one exception (which was a div. 1-only anyway), but a couple people off the top of my head who do are SecondThread (example) and Um_nik (example) [others may feel free to self-advertise as well if they fit the description]. As you would probably expect, commentary is light/nonexistant, but that's probably the best you can get. Is that what you're looking for (or rather, which ones have you looked at)?

          Thanks a lot! Um_nik's screencast is exactly what I was looking for and it really demonstrated fast submissions. There's a lot to learn from it.

          As for SecondThread's screencast, it looks more like an artificial spectacle than a real participation. I suspect (but may be wrong) that he could have solved problems A/B/C faster if he didn't have to provide commentary. Spending 3 or 4 minutes per easy problem is okay. But I'm spending 3 minutes on super obvious "add two numbers together" style problems myself and want to figure out how to reduce this time.

        A quick search of "codeforces global" yielded plenty of screencasts. In particular this one shows tmwilliamlin168 doing Global Round 10 A, B, C in 4 minutes: https://www.youtube.com/watch?v=ep3UQkoRunc&list=PLz4C07Cc_cukHOBF9khFBnJz0PKIQC3uq

        There doesn't seem to be any special tricks or setup. Just read/think/type faster.
