    I really appreciate how you said at the beginning "Do you understand this? Because I don't, this is too thick for me, but this is the typical introduction you'd get in actual classes". This whole sentence resonated so much with me. Sometimes I cannot grasp those abstract ideas in math, and I just need to have the concepts explained to me like im 5 years old, and your video was able to make me understand this in just 20 minutes, when I've been struggling with this for 3 years. Thank you man, keep it up!

    I had to pause the video to take the time to say this. Your videos are absolutely phenomenal. Keep up the good work man, your channel is 10x better than all the others I see that just tell you "how" to do something but don't go over the "why". Great stuff man, your channel will grow soon enough. Definitely recommending this channel to all my other friends.

    This is my first comment I've ever written on TH-cam that I can recall. There is no better opportunity than to give you feedback as my first post.
    I want to personally applaud you, not just for your excellent teaching (you a BEAST!), but the effort you take to thoroughly respond to all of your subscribers. That speaks volumes. This is what stood out to me aside from your incredible ability to convey these complex topics in an understandable way. You won my subscription.
    What sets you apart from many other channels is how humble you are. You don't proclaim to be born as Knuth's twin brother or anything like that. You shared with us how you personally struggled with the same concepts that we now are an audience to. This quality makes you tangible. It draws people closer to you: "Hey! He was once where I was. I'm not alone. I can overcome these obstacles like he did!".
    On that note, keep up the remarkable work. You have a gift and people out there in cyberspace are watching.

    Thank you so much for explaining this. As a graduate student in my 5th year of CS, I have only had bad luck with professors. No one would ever use examples or simplistic breakdowns to explain the concept, as you did in this video. You state the problem, simplify it, solve it, and work back up to the complex level we started at, in a way that makes it easy to understand, and very easy to follow. My assignments finally seem clear to me now. You've earned a sub :) Have a good week!

    I can’t wrap my head around how such a young guy can have such a better grasp of these concepts than the professors at my university and the textbook they gave us to use, and all the other people who are made of TH-cam videos on the subject. Oh, and my useless tutoring center. all of these people and resources don’t understand the concept well enough to actually test it. You are amazing!

  • @JeffCaldwell-nemo_omen
    @JeffCaldwell-nemo_omen 2 ปีที่แล้ว

    It took this video to make me realize that my understanding of what something like `f(n) = O(g(n))` means was completely backwards. I thought it meant that f(n) must be larger than g(n), but nonono. Whatever g(n) is needs to be larger than f(n).
    Wish I'd seen this before my last assignment. Glad I saw it before the first exam. Great video!

    Wow! Finally, you are back man. I have been confused by a very simple question in leetcode recently, which is a climbing stairs problem. It could not be that hard! But I just can not figure it out by myself! Could you help me out of this? Here is the description.
    You are climbing a stair case. It takes n steps to reach to the top.
    Each time you can either climb 1 or 2 steps. In how many distinct ways can you climb to the top?
