My Competitive Programming Journey (and how to practice)
Переглядів 139,037
3 роки томуHere's the stuff I mentioned in the video:
USACO: www.usaco.org/current/index.php
USACO Training: train.usaco.org/usacogate
Codeforces: codeforces.com
CodeChef: www.codechef.com
AtCoder: atcoder.jp
And a cool site that lets you see difficulties and stuff for AtCoder problems: kenkoooo.com/atcoder#/table/
This is a special video for reaching International Grandmaster on Codeforces. I'll probably do more of these for some sort of milestone special, so the best way to see more is to subscribe :)
By the way, we're hosting the Montgomery Blair Informatics Tournament on November 14! It will be much like the contests you're already used to, with problems authored by my school's programming team. Registration is open now, and you can see the competition's rules, format, past problems, and info for registration at mbit.mbhs.edu/

Nice video Colin. I think it is good to see that the way was not as easy as it seemed when looking at your ratings. I personally liked the part on how you coped with failure the most. Respect on putting in this much effort in your early years. I spend my highschool time on a lot of really useless stuff :-)

Loved this kind of content, really honest and encouraging! 💪 Not too much is being said about ranking stress, failures, and discouraging contest results. Usually, red coders seem like ppl from another world with just higher IQ, and it might be true for some, but can also be a mindset trap to avoid keep trying after failure!
@anmol_tomer 3 роки тому
Really great advice, I think sleeping schedule thing was my favourite, because I noticed that as well, due to lockdown we have online classes so I get more time to sleep and these days I really feel great while giving a contest when I've had proper sleep. Please continue to make videos like these. Really great content. 🙌🏻🙌🏻

That's what USACO training is for. And to be honest, for beginners, it's so much more about practicing general problem solving than learning specific concepts. So such a list isn't really necessary.

You also spoke about practicing on Atcoder, as it has those AdHoc Problems, which generally helps in improving the thinking ability. But, how did you practice over there? What I mean to ask is, that I think we cannot sort the AtCoder Problems in some difficulty order, or solved count. So, could you please throw some light upon that as well.

@08ykr22 3 роки тому
Thanks for the helpful video. How imperative is it to have a strong knowledge in discrete mathematics to excel in CP?
@ColinGalen 3 роки тому
I don't think it's necessary as a prerequisite, however, coming in with knowledge about its concepts (like combinatorics & graphs, from what I know about it) certainly can't hurt. In general, I think you can learn basically anything required for CP in the context of CP, meaning that even without prerequisite knowledge, you can still be able to learn and apply it.

Could you share with us your schedule ? (In the morning, you started practicing when ..., how many problems ..., how long to think on 1 problem ..., in the afternoon, evening, ..., sleep how many hours ...) Thanks!
@ColinGalen 3 роки тому
It wasn't really a rigorous schedule. I just did normal stuff, went to school, (tried to) swiftly finish homework, and when I had free time, I would spend it thinking on whatever problem I was currently stuck on. Sleep was relatively normal, went to bed around 11-12 PM. Typically I would try to think on a single problem until I felt completely tired of it - not just stuck, but so lost that I felt that any more time spent would just be a waste, and this often only happened after multiple days.

Yeah, their competitions are totally not required. In fact, their problems are usually available around a week after each contest, so you'll still have access to them even if you don't do the contest live.
