Please, try to read this Galen. A thanks to you. I practiced a lot (for 3 years) and never got to be an expert. My practice method was basically choosing a problem of 1700-2000 difficulty and trying it for 1 hour. After that I've always read the editorial or seen someone else's code. Like that I've done (not solved) 1500+ problems over past 3 years and 10% of them were actually solved by myself. Then I've started watching your videos and learned that you emphasize on thinking for a long time and I thought, "ok, let's give it a try". You know, I've solved 11 problems of 2100-2200 difficulty (non dp, dp is my weak spot, I'll train it later) this month and you know what, my rating is now 1700+. And now I like to think about solution for 2-3 days no matter how difficult they are. Feels like a problem solver rather than a coder. Thank you very much Galen.
yeah, you mentioned very good point, you have to solve it on your own, but you missed some point that, sometimes we might not have an enough knowledge about what if there are another appropiate topic we can use on solution, or you may not know that topic for solving that problem, so what will you do
Could you describe your thought process and its types? E.g., materialization (thinking about something's individual parts, interactions, functions, and bringing things into a more material/graspable form.), interpretation sense (the ability to sense when your interpretation is off and to focus on fixing it), answer tracing @ scanning (thinking of all the ways one might arrive at a conclusion), etc.
i will do 10 times of this and will really see what shit happens or nothing happens .This is promise under 4 months . I am actually tired of this video , that video , nothing works ... now while starting i got a question why this video . Really this comment i think really carries something in it . I am tired a lot , oh god , which questions , what questions , some hard or what , so much time wasted , looking others growth in cp and me not even improving is quite frustating , oh god , is there something for me in this , others improved so rapidly , how much foolish and dumb am i , people do and ppl CM , now looking that mind says fake person fake profile . but i can not even do that , i should stop seeing others .. then mind says till what u will do random problems , no use of them , u can not be great person with that . Then mind think of tourist like person . No No he is be very genious solved buoyancy without archimedes principle . he just comes in cp to show off , ohh bro what feeling put in blog , already capable just showing their useless efforts , i am kind of bored with problems , ohh what should i do . I do not why i even started it (of course not cp , why this line )
6:53, Neetcode also used spreadsheet to record each problem analysis along the leetcoding, quite useful for reflection. I think your metacognition is quite useful to record the mind flow~
Analysing metacognition might not be recommended and required for beginners. Its only after you get good at the game and you need to micro optimize your thoughts.
What i do is to construct the generic version of a algorithm in my head and argue about every step until it makes sense. When im in bed for example, i think about how to reverse a singly linked list or a generic BFS, when i am able to do this i know i can recall it from memory whenever i want, building the fundament and later i am able to change it in code to what i need. I guess the trick is to be able to construct the whole thing in your head without any other stimulation or hints. Works for me

1. I just do whichever problem, any type. doing different problems allows me to creatively reuse those thought process that led me to solve a hard problem for later problems. 2. I then practice by solving specific problems of only a certain type 3. improve solving speed, usually from lots of experience in observation problems, and good implementation skills and tricks. to improve, i am studying classical algo/ds. practicing ad-hoc and non-classical problems are good over time, classical knowledge just becomes common sense. no doubt, problem solving intuition will get stronger. c++ knowledge, good code readability, and usage seems to be a good thing to improve imo

Great overview. I have only one minor note: for me, most of the useful reflections happen **immediately** after I realized what idea I was missing to complete a solution. Moreover, I sometimes find my conclusions from reflections done long after the contest faulty, as they do work for slow-paced practice but not in the time trouble of a real contest. But this thing is hugely personal, so idk, use it at your own risk
To Colin or anyone else, To you folks see loop invariants as a effective thought process? It helps me a lot in some problems. Also thinking about making progress in each iteration, guarantees for termination and so on help! Any other thinking paradigm you folks follow?
Key learning from this video 1> If you cannot resolve a problem that you did before you didn't learn enough from it. 2> Choose a problem that is difficult for you or Helps you to learn a new topic(allocate more time in the thought process around 30 minutes) and code the solution once you understand it. Note down what you are thinking of as you do it. 3> If something goes out of your head, run after it. 4> Metacognition -When you are solving a problem note down what you are doing and when you look back at these notes you will know where you went wrong(and the best way to do this is by recording). 5> Once you are done with the problem maintain a spreadsheet where there is a summary of the solution. 6> Make sure you know how to use big ideas/topics from solved problems. 7> Treat every problem as a learning process. 8> Your practice will tell you what topics you need. hope it helps it.
This video helped me understand that I can do it too and I loved how you sort of gave a "template" on how to improve. Thank you so much for posting this, Colin 🙏
Hey Collin hope you are doing great. I have a request for you. Can you please make video on interactive problems, i mean what kind of problems are these and how to attempt them. I am a beginner and recently while practising I encountered one. Please if it is possible make one. Hope yuu will see this comment.
When I pratice then the only problem which I face is not understanding the editorial, like I have no issue putting in the work but after all that I'm still not able to understand the editorial? Any solution for that?
He said in the video that you may not be able to understand the editorial from the first time. Try rereading it later, if it doesn't help go ask help, on errichto server for example
Thank you i will have to reword my problem solving I solved 100+ lc problem but still cant figure out most of them so I guess my approach was incorrect.
I know you have a number theory video...but can you plz make one on chinese remainder theory? Been looking for one but i can't get it....Lets make one starting from the beginner steps then solving to kind of complex problems plzzzz in c++
Does it come up often enough to warrant a whole video? On Codeforces, there are only 13 problems with that tag (out of over 7,325). I don't know where to find problems on it anyway, other than the codeforces tag.
@@ColinGalen okay i just wanna know how to practice in such cause of my cryptography class...if you can help out with the implementation walk through i will be able to take it up from there.
Not sure if I can trust your strat. Clearly you just have high aptitude if you shot up from ~1600 to ~1900 within the span of about a month. You'd probably be able to use any dogshit strategy and make some serious improvement

I loved the idea of getting as much information from a problem as you can. Feels like the right way of learning!
Making notes of the thought process for a problem sounds like a good idea, I will definitely give it a try.

Exactly . That's kind of like what intuition is.
One should definitely practice watching this video regularly.
I had never thought about meta-cognition the way you explained, this is unique!
Thank you!!

this is the principle of deliberate practice, it's like learning to touch-type, its grunt work. thank you for your contribution...
Great advice. I've been programming for many years but I really want to become pro.

Btw so if I solved 680 problems but some of them were reading the editorial, should I resolve all 680 problems???????
