Congrats on IGM and 7*,en exceptional achievement at that age of yours as any sane person would reckon! A big thank you for the explanatory videos, wishing you good luck for the future, and looking forward to learning much more from you!
Really impressive journey and I'm sure this will inspire many more to follow in your steps. Congrats on IGM and 7 star (in such a short time too) and I wish you all the best for the future!
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!
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. 🙌🏻🙌🏻
I think sometimes motivation is great better than on contest because it boost up and gives the answer why he not me, which we can't learn from giving contest
Hey, thanks. You inspired me to dive into competitive programming. The thing is I have 2 chances of participating at IOI, I'm currently 1201 rating on Codechef after 8 days of practice (250> ploblems solved). Started 02.06.22
@@nahrafe Hey, thanks! I've made a lot of progress over the past 4 months. I hit 1760 (Codechef) rating yesterday. And I have become confident solving hard problems with rating above 2000 during contests. I am so close to 4* and I am planning on getting 5* by the end of 2022
what is your advice for a beginner .. Do i have to start usaco training or continue with codeforces / atcoder ... I want to improve my rating in codeforces and skills in competetive programming... I have been solving codeforces and atcoder problems for more than a year but there is no progress in my rating and i am still stuck at newbie
I suppose, if what you've been doing hasn't been working, then it can't hurt to try something new, right? I think USACO training is amazing because it forces you to adopt the learning mentality.
Well competitive programing needs 2 things 1.Ability to problem solve 2. Knowledge of algorithms and patterns since you have been doing codeforces you probably already have some grasp on the 2nd part which means you probably need to improve your ability to think and solve problems. How do you do that? I dont know really what the best way is but im sure google knows!
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!
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.
Silver p2 and gold p2 from this year: www.usaco.org/current/index.php?page=open19results Silver was squeezing an unintended O(n^2) solution past the weak test cases Gold was using an unintended math solution (that was actually very easy for them to counteract, had they known it) for what was supposed to be finding a minimum spanning tree
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.
Ah. Thank you, that's something I should have mentioned (and will now be in the video's description). There's this cool site called kenkoooo which basically lets you do exactly what you mentioned. Here it is: kenkoooo.com/atcoder#/table/
That was a pretty good path for that period of time, congrats mate! The things that I hope to workout from here are *Fixing my sleep time *Doing contests and upsolving or at least try to understeand what the thought for that problem was *Find the sweet spot to practice, not too easy, not too hard Let's see what happens :D
Would it be fine to use the USACO site/USACO training portal strictly for practicing and not be hassled into their competitions and all the other stuff? I’m mainly looking into competitive programming as an outlet to brush up my coding skills while having something to occupy myself in college.
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.
I think, as soon as you can start. Contests help you know the exact type of things you have to solve/know, and the more you do, the better your mentality about them will be.
It took me 6 months to reach 6 star on cc and 1840 on CF and don't see any progress for the last 2 months, or actually falling on CF, how do I get a progress, please suggest and help.
I was also high blue for a while. You probably aren't stuck, it's just a difficult place to get out of. Most likely, try to fix any mistakes you've been making lately, keep practicing the way that got you to this current point (mixing in new concepts if necessary), and you'll probably break this wall in time.
That's so great man but can you please make at a list of all algorithms and data structure which are useful in competitive programming and all other topics which can help other noob programmers.
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.
Great guideline for newbies like me!! Can you tell me one thing! How and from where you used fo learn new concepts and master them! Please clear me. I'm stuck at same stage for last 2/3 months. Just solving codeforces Div 2 A, B. Hardly the C problem. I'm not getting any idea about how to learn new data structures/algorithms and implement them.
USACO Training (as I mentioned) has most of the necessary things for beginners, and with that basis, it'll make it easier to learn more advanced things.
@@ColinGalen I have already started practicing on USACO training. Completed few ad hoc problems(section-1.1, 1.2). Now solving Complete Search(Section-1.3) problems. But here only I can find is problems with few short introductions on those concepts. I still couldn't find any tutorials/resources on USACO training. :(
@@asifanwarsajid8332 The later chapters (e.g. 2) have articles and problems on more advanced topics. The beginning section is designed for people new to CP to get them used to problem solving in general.
Would you recommend usaco for a beginner. Like i was doing codeforces and i still remain as a newbie and i did work hard, but was not consistent enough. Now I feel like i messed up everything can u suggest me what to do next?
I guess for those you'll have to just know the trick and be able to apply it (if I understand you correctly), so having a strong and broad conceptual basis should make that easy most of the time.
Depends on your current capabilities. I would recommend working on everything you're currently weak on (conceptually) then trying to improve ad-hoc/thinking skills more.
How can I improve my thinking ability? I know flows, segment trees, treaps, etc... But sometimes I just get stuck on a simple ad-hoc one-liner because I'm so used to "blindly applying data structures and algorithms" as you said :(
It's about practicing the problems that force you to solve them without being able to apply any concepts - e.g. adhoc (codeforces A-C generally), constructive, interactive problems
Dude that's really great! I've been practicing a lot and finally reached cm a contest back. Can you recommend anything useful, or any experience that might be useful to remember beyond this point
I think you're doing great, and whatever you've been doing to get this far will probably still work for a while. If you feel stuck, you can always try switching it up (e.g. to different platform), just because it can be kind of refreshing.
also do you have any advice on knowing when to move on to a higher level of problems? Like ik that I shud solve problems until ik how to do that level but how many problems should I do until ik I am done with that level?
Great video! Can you give advice on what to practice, I am stuck on 1700-1800 on codeforces for nearly about 3 months. I am practicing problems of around 1900-2000 in codeforces what else should I do?
