Hey Jeff, Please cover all the topics from data structures and algorithm. Thanks
Yes plz!
Yesss! Like this comment, get to the top!
Yessssss fully agree
YES PLEASE :D
Yes
Do a series of these different Algorithms.. Helps immensely in quick revising them for tests..
Yes, please. I've been having a hard time implementing variations of DFS and BFS graph algos.
@@WTHBrou I keep failing hard at graphs interview, I second that
Yes, please.
MOAR ALGORITM PLS
Yes. A series, then put them in a playlist. CS 101. You'll get tons of students into it. I can already forsee teachers using Fireship videos as introductions for every (available) algorithm.
This is amazing.
I would call the series “demystifying Algorythms”, or “computer archeology”, or “understand the technical interview”
That's a great idea you got here ...
aaaand thats why no one asked you
A playlist of common interview questions would be a godsend
More algorithms please, I was just looking this up yesterday and found this video explains it more clearly than others because you clearly explain WHY we would use this rather than just parroting how to do it out of textbook.
If you're a CS student/beginner learning data structures & algos for the first time, I cannot recommend "A common-sense guide to data structures & algorithms" enough.
It's a textbook that is focused on explaining the base concepts in plain English to a beginner. It goes in-depth without overwhelming you. Provides exercises, examples, & diagrams.
Book saved my life freshman year of CS.
@@m1rac1e bro i am gonna be in freshmen year in August, can you please give me the link to download it.
I would like more algorithms because I like algorithms, but this is a hardly revolutionary video. Here's to generic praise 😂
@@shreehari2589 look up textbook piracy, can't link it because youtube filter blocks me.
gotta use ur brain.
@@shreehari2589 try z-lib
I finished my engineering course long back, but would pay you to watch data structures and algorithms explained in such a nice way!
bru
Well, I knew binary search already. But this dictionary anology was just amazing.
i think cs50 does this
Holy moly! Ive never seen anyone explain it as simple as this. Please do more data structures and algorithms stuff. Thank you
This was so awesome, as a self-taught developer I never got to learn most theoretical things like this, and it definitely has an effect on my problem solving
More algorithms in under 100 seconds like these, please! This was explained way more succinctly than a regular class would have done.
Love to see more algorithms videos! 👏🏻
I really love these videos. My favourite dev content on TH-cam. Perfect balance of knowledge, time, humour, and impact.
What a miracle. My computer science teacher taught us linear search today. And will teach binary search tomorrow. I got it easy 😊
Yes, continue with more algorithms, this was so easy to understand, thanks!
Man, you've come at a perfect timing for this one! Would love to see more about algorithms.
Definitely keep making these. I'm a full-stack developer, but missed out on a lot of the 'low-level' knowledge like algorithm design and Big O notation. This video was incredible!
The code shown actually have a bug. When it was written back in the day it was not a problem. Now of your search array has billion elements the sum of integers may overflow and become negative. The new proper way to avoid going out of bounds of the integer to calculate mid point is
int mid = low + ((high - low) / 2);
This was a bug in Java for 9 years
This is actually really important. I’ve gotten dinged for this.
To be fair, he did say the code was in JavaScript.
But this is still an important insight you’re giving
No only that, this kind of iteration is really limited in JS (in fairnes JS is not a declarative lenguaje and has the while loop for this kind of problems), you going to get a "Maximum call stack size exceeded error" before getting this bug.
@@jandresshade Why would you get a maximum call stack size exceeded error?
I don't get it. Can you explain?
I’d appreciate if you make a series about data structure and algorithms. Your explanation is really helpful!
Thanks:)
Wow. The simplicity is amazing. Would love more of these. Thanks
Need many many more videos please ❣️
Sir taught in class many times but never able to explain like this. Thank you ❤️
This is the first time that I truly understood the Binary Search algorithm and how to implement it using recursion in just 2 minutes.
Awesome!
This made more sense to me than when I learned about it during a 2 hour lecture. Would love to see algorithms more
love it! these are great for practicing for coding interviews - especially if you cover more complex topics that are hard to visualize (dynamic programming, fast/slow pointers, loops etc)
Hi Fireship, I am learning data structures and algorithms. Please continue. I actually like the way you simplify things.
Algorithm holds a massive part in today's technical world. Apart from dev tools like react, redux, and all including devops, algorithm is something we all get to ask even in interview.
I appreciate the work you have done yet and doing continuously to get us know what that technology actually means and when should we have it in use.
Other data structures and algorithms are welcome from my side. We all need it.
We need more like these algorithms
This is pure gold, and yes, the crowd cries out desperately for more videos of algorithms and data structures. Keep it up man, thanks!
Please continue to release these videos. Algos/DS are always top of mind for most folks interview prep, amazing stuff as always.
What took my intro to data structures/algorithms professor weeks to each you succinctly explained it in less than 3 minutes. I appreciate your work a lot!
hey this was really informative and interesting to watch all while being entertaining because of how good your animations are. please keep doing more of these 👍
Who's gonna tell him that these videos are all 150 seconds long?
Short and sweet (as usual). Please, keep them coming!
I hadn’t been able to picture divider-and-conquer algorithms for weeks, until this video. Thank you so much.
Please do more Algorithms! I'm practicing Leetcode so this video is incredibly helpful in explanation. Time Complexities are a harder concept for me so this helped explain that a little more.
With Jeff's videos we can speedrun learning!
I know this is a relatively old video, but I love these algorithm videos, please return with more of these in depth algorithm videos if you feel like it:)
Great video! We would love to see videos like this for all sorts of algorithms. Even compare and contrast different algorithms(space & time complexity, etc).
Hey Jeff, great video! How about a new series where you show most known algorithms in 100 seconds? That would be great!
That's a really cool format for algorithms showcases! Keep it up!
I absolutely need more algorithm oriented content this is fantastic.
I wish I didn't know how binary search works so that I could enjoy this video more
I would use the .indexOf() function instead of a for loop
Thats Language feature not available in all languages and you aren't allowed to do that
Love this series on algorithms! You should do more
Videos about popular and lesser known algorithms would be great content. Would watch them all!
This is a good video. But I see one flaw in it. You haven't explained the fact that binary searches work only in an environment where everything is sorted
0:39 "given a sorted array"
in a 100s video every word counts
First
didn’t ask + don’t care + ratio
Ratio
🥇 Gold!
Beautiful! I want more videos like this! Common algorithms explained and implemented.
This is awesome! More data structures and algo videos please :)
You are a genius at teaching, I will watch and use whatever content you make, including more algorithm vids.
It would be great if you could cover the most common algorithm and data structures topics that are asked in interviews. Also, topics like solid principles, deadlocking, etc. Your videos make a great refresher for any concept without being boring. In any case, thank you for the great work!
I already know this will be a great mini series!
This is the best explanation of binary search algorithms I've seen.
Absolutely want to see more. Keep them coming.
Loved these 100 seconds. I happen to find my best 100 seconds for today. Thanks Jeff. 💚
would love more videos about algorithms like this video concise and to the point and with an example to understand. Keep it going
Yesss! love the algorithm explanation! would love to see more like these
I don't comment much, but this is probably the most useful and efficient 100 seconds that I can ever give to TH-cam. Please make more of these!
Woah, that's pretty cool! I knew how to do it but by using a recursive function it was definitely a much different approach I hadn't seen before. Looked so much better than a binary search algorithm I had made earlier.. The explanation was so much simple and straight forward from the one in my textbook. This is absolutely amazing!
Yes, Please to a complete series on all algorithms and data structures, it'll be really helpful.
Love your short videos and if you explain data structures and algorithms like this it would help me a lot in my university!
Greate idea to make algorithms series. keep doing it and thanks for your wonderful content and simplified description.
Very informative! Need more videos on algorithms!!
Quite an interesting algorithm and certainly one important for all developers, regardless of language or field. The video explains it quite well. Keep up the good work Fireship!
Your method of teaching both in the "to the point" time constraint and the visuals have really helped me better understand what a lengthy memorization-centric course fails to do.
Yes, we need to see more videos about algorithms and data structures please!
Amazing explanation for a common problem that is very helpful. Please do more of this!
Yes please do more algorithm videos🙏🏾; great video btw!!
Yes, please more videos like this. And thank you for all your work!
Amazing video. I would love to see more algorithms explained like this.
Amazing video as always. Implementing most of my loops with this will probably speed up my code 🤯
Once again this man has made me understand code so much better
Need more 100 seconds of algorithms. So much fun to learn it this way.
Love it. Please more algorithms videos!
a playlist of data structures and algs videos from Fireship would be a lifesaver
This was brilliant. Please do make more videos on algorithms. Cheers!
Great video! More algorithm-type videos would be awesome!!
This channel is so good it's raising my ADD everywhere else.
Nice video! I like this more than going over really complex subjects in 100 seconds because you can barely scratch the surface there. This now really explained a lot of the approach already.
Question by the way: where do you get your emoji pictures like the pointing hand from?
Much needed refresher. Need more of it.
yes, I'd love to see more videos on this topic please!
I hope there will be more videos of that type, you explain Algorithms in a very good way.
hey Jeff this is a great video 👍🏼, make videos like this about algorithms in the future
Simple, short yet great content. More on algorithms please.
Yes please! Great job at simplifying it. Way easier to understand than via leetcode
I love this type of videos, please make more of these ^^
This was a really cool video, keen to watch more
More of these please!!!! So well done
Four years of CompSci Degree, three years in the industry and I just got a grippy example for a recursion. Thank you a lot, Jeff!
I would mostly certainly love to see more videos on algorithms and data structures
This is the simplest and understandable explanation I've found on this topic. Thanks!
Expecting a full animated Data structures and algorithms course on this channel
Please dont disappoint
Just learnt this in Computer Science, this helps my knowledge even further
Yes we would like to see more algorithms videos and also data structures as well
Well explained, Please continue making algorithm videos
You explain that in 2 minutes better than any of my professors could in a half hour. I would really love to see how you present dynamic programming, maybe with a genetic sequence alignment example.
You’ve done it again! So concise!
This is amazing , more algorithms in 100 seconds please
Yes a series of these different Algorithms would be great
Simple straight forward videos abt data structures & algorithms, YESSSSSSSSSS
This was such a great refresher for me man thanks a lot 👊🏼
Yeeees we need MORE of these that was actually so good !
