Cleanest DP intuition video on RUclips, I have watched countless of them but this step by step like exactly how we think during an actual problem solving process is what connected with me. I really wish you make more videos but from the perspective of how a person who is leaning will think and solve it.
The worst problem about the Leetcode interview process is that is forcing engineers to memorize instead of thinking. If 20 years ago someone told me that in the future we will be selecting engineers based on a memorization process I would laugh. In a job market where everbody memorizes patterns an algorithms, these kind of breaking a problem in parts explanation is fresh air
i really hate that too. I am a strong advocate for easier problems with more scrutiny on explanation and correctness. There's nothing more I want to see gone that questions that have an easy to remember trick solution and poorly trained interviewers just looking to hear THEIR answer.
@@DecodingIntuition indeed. It probably has a higher recruiting cost but I would rather evaluate the thinking process of a candidate instead of the same candidate faking that thinking process because he grinded that Leetcode exercise
if you're memorizing leetcode, ur doing it wrong. i can solve pretty much any leetcode problem (tho some hards are tedious) and ive never memorized anything
This was genuinely mind opening. Thanks for this. It's not often you feel like you a video has made you better off after having watched it. My perspective on problem solving has improved having watched this. Now its all about practice.
To be fair, it is really hard if you don't know that DP is not about drawing arrows on random tables. Once you get comfortable with the idea that you can efficiently use a recurrence relation to simulate all possibilities, coin change really does become as easy as "take the coin or skip the coin" :) I'd really love for him to see this video and see if it changes his mind about it, because he's a smart guy and I'm sure if he knew what dp actually was he wouldn't have spent over an hour on it trying to pass art class
I started Programming two months ago with high intent to go competitive. This is my favorite vids as of now that makes me comeback for another watch every 2-3 days or so. Absolutely beautifully taught
Really just getting started into programming and a friend sent this video to me. I think I got quite a bit of it, but this gives me SO much stuff to go and track down and learn. THANK YOU!
DP is hard because the algorithms look like a complete enumeration, especially in optimization problems. Half of the process is to convince yourself that the memorization you've thought of saves enough time in your specific case. This approach with cached complexity simultaneously derives the algorithm (just enumerate every state via recursion) and calculates the complexity for you (the recursive call is O(1)). It is then easier to derive a non-recursive algorithm from the recursive, and the memorization table is a matrix with a dimension for every argument of the recursive call.
This video is so good. Not just for DP, but general problem solving. Also, I really appreciate the notes slides you put in the video, that saves a lot of time and helps me understand the content better. Instant sub.
This video is amazing! The confidence you express your ideas with, combined with you immediately backing them up, really helps the ideas settle in my head. I especially liked the example problems at the end, after watching the video I had no trouble at all, which is usually not the case for videos claiming that something is "easy". I didn't even especially struggle with dynamic programming in school, but this definitely helped cement my foundations. Thank you!
20:28 This meme highlights the main misconception I have had forever, also loved the department of defense trivia. Holy moly the fact that no one ever mentioned or highlighted that recurrence relation != recurrence execution to me before is such a scam. In fact I was made to think recurrence execution is what happened in the call stack (even though I didn't know how physics allowed it). SOOO GLAD to have cleared it up. Drawing down the entire trace graph of calls always got me stuck and felt unintuitive, since I didn't know how my computer processed it. I also got lost when drawing it down. "Decisions are Values to compute once and not task to run every time" THIS QUOTE AND VIDEO IS LIFE CHANGING Its funny I got a non-dev job as a new cs grad, but videos like these are perfect/motivating as I love problem solving and want to keep my skills sharp even if my work right now is in a different field. Since problem solving is a universal skill. Can't wait for the next video since I never truly understood memoization and other space/time optimization that people usually did when solving such DP problems. Or even other LC type problems. I just love that you are focusing on problem solving more than just leetcode, please keep it up!!!! This is a niche (math/cs/leetcode/problem solving) that i always thought lacked good youtube content.
THANK YOU, this video is really opened my mind. I have solved 300 problems on Leetcode, and I can solve most DP problems, but my confidence on DP is little. Your process to observe/break down a problem is phenomenal, and I feel like it just should like this all the time. I will share video to all my friend who can code, and just try to solve the two DP problems that I can't solve.
Please, I need you to MAKE MORE VIDEOS. I don't care if it's about the most useless data structure or algorithm of mankind, with this video you show that intuition and the process of building a solution is imperative to understand whatever THE solution to the problem means, even if it's a hard problem. I urge you to keep making videos, you help people like me (too much). I REALLY appreciate the time people like you take to explain any concept. Thank you very much.
@@DecodingIntuitionanother person here - I share one for one, exactly what this person has said. There really is NOT a lot of people on RUclips that walk through the ENTIRE problem AND process. Please continue making content bro 💪🙏
@@Hellbending That's my goal! I don't just want to tell you why I know a solution works, I want to show how I arrive at it. There's plenty of great content that explains why things work, but I'm here to try to fill the gap for the other :)
Please do make these kind of videos more often, I am a software engineer for over a decade now and I feel to go back to roots again just because of this video :)
The DP section of this video is good, but the greater value I garnered from this was ACTUALLY applying the breaking-down-the-problem strategies we are taught when approaching leetcode-style problems. These are things I have been told countless times but have struggled to break things down to their core components, but after watching you do it in this video it has really revitalized my confidence. Well earned like and sub, keep up the great work! Would love more videos like this.
awesome vid, coin change being the example here is a huge bonus for me because that problem has been fucking with my head for a while even after looking up the solution
@@GRAYgauss it's only "not actionable" if people make promises they cannot keep. it's a simple rule of thumb: if you aren't sure you can keep your promise (to the best of your ability within your control), don't promise. extenuating circumstances such as death and traffic apply. for our own sanity, we must assume that lexical and logical ambiguities of promise statements have been previously resolved and agreed upon by all involved parties. for example: Scenario 1 - Alice knows they have (2 + n) chocolates in their chocolate tin, such that n > 0. Alice promises Bob 2 chocolates from their tin. Alice then gives Bob 2 chocolates from their tin. Nobody knowingly made impossible to keep promises, everybody's happy. Scenario 2 - Alice knows they have only 1 chocolate in their chocolate tin. Alice promises Bob 2 chocolates from their tin. Alice is clearly lying and should not be trusted with the secrets of Quantum Physics. Oh, and not to keep promises, either. Scenario 3 - Alice knows they have (2 + n) chocolates in their chocolate tin, again such that n > 0. Alice promises Bob 2 chocolates from their tin. When Alice and Bob open the tin, the chocolates are all melted. "It's okay," Bob says. "It was only thermodynamics." Nobody knowingly made impossible to keep promises, everybody's happy. feel free to ask any questions or present your viewpoint. i'm happy to discuss my viewpoint on this subject further.
The part about time complexity and thinking about the size of call stack in terms of unique states is really great, I've never though of computing the complexity that way before even though it seems intuitive when you actually think about it
These videos are very thought-provoking. I really like the presentation of this concept, which has traditionally been hard to follow. One request: I have found that the best way to truly integrate a new concept is to have both a good explanation, and also several fully worked examples. This lets me “triangulate” the concept better. Would you consider uploading a third video where you just work two or three full examples using your approach. No need for a lot of explanation, your first two videos cover that, just provide several examples we can use to triangulate the essential characteristics of this tricky concept?
Very good video. I got a google thing in my gmail and I am not as acquainted with leetcode style problems as I should be. I will do the notetaking methods next time I get the chance to do coding problems. Having all the info right there and breaking it down live seems like a good thing to do. Thank you!
I'd love it if you could share resources to learn such cool stuff or any materials you've used for this video. This is super helpful and thank you for this !!!
Your analogy of treating every function call as a "state" with some fixed value and some state variables really helped clarify dynamic programming for me. I bet there's going to be O(views_on_this_video) increment in dp solves on leetcode now😅

My first task was to find a name for multistage decision processes. “An interesting question is, ‘Where did the name, dynamic programming, come from?’ The 1950s were not good years for mathematical research. We had a very inter- esting gentleman in Washington named Wilson. He was Secretary of Defense, and he actually had a pathological fear and hatred of the word, research. I’m not using the term lightly; I’m using it precisely. His face would suffuse, he would turn red, and he would get violent if people used the term, research, in his presence. You can imagine how he felt, then, about the term, mathematical. The RAND Cor- poration was employed by the Air Force, and the Air Force had Wilson as its boss, essentially. Hence, I felt I had to do something to shield Wilson and the Air Force from the fact that I was really doing mathematics inside the RAND Cor- poration. What title, what name, could I choose? In the first place I was interested in planning, in decision making, in thinking. But planning, is not a good word for various rea- sons. I decided therefore to use the word, ‘programming.’ I wanted to get across the idea that this was dynamic, this was multistage, this was time-varying-I thought, let’s kill two birds with one stone. Let’s take a word that has an absolutely precise meaning, namely dynamic, in the clas- sical physical sense. It also has a very interesting property as an adjective, and that is it’s impossible to use the word, dynamic, in a pejorative sense. Try thinking of some com- bination that will possibly give it a pejorative meaning. It’s impossible. Thus, I thought dynamic programming was a good name.
