Hey what was most common solution pattern?

[@sowoul_]

im a leetcode knight (1872) and have 600 problems solved. Always lovely to see new programmers start leetcoding!

[@sinatfahad2283]

I literally SUUUUCK at DSA. Can you guide me like how I should start learning and practicing? Although I have been saving playlists but getting too tough to understand.

[@Green-Code]

Wow. Respect.

[@scarymojo5809]

@@sinatfahad2283 Learn basic dfs, bfs, binary search and how hashmaps and arrays work and that should be enough to start practicing. I would look up dfs algorithm etc. for all those topics and once you feel like you understand them conceptually, solve a leetcode easy to reinforce your knowledge. This should be enough to start.

[@PixVox]

How long did it take

[@LordVlader]

@@sinatfahad2283 Start by watching the DSA video from freeCodeCamp. It's explaining the very basics in an easy to understand way.

bro the lip syncing on your animations are mad accurate i love it

he made them manually or used some AI product ?

[@goos42]

​@@harshvardhan-d5e my guess is some sort of program which takes his mic audio and when it sees a certain volume spike or some other pattern it changes the sprite. At least that's how I would do it

[@Latestfit]

HOW TF ARE YOUR ANIMATIONS SO ON POINT, even the lipsyncs are so accurate

[@ZaneMouakket]

11:21 Both of those solutions are DFS, one is iterative DFS, one is recursive DFS

Yeah yeah I know :) I just think recursive DFS is so much cooler

you know that's impossible right lol

[@SamDaBest]

It’s not that hard tbh. But you definitely need to work harder than doing leetcode

Edith is awsam bro. The way you explained was great.

[@musab9334]

I just solved my 100th question today on Leetcode, with 5 hard and 41 medium, and, it was hard. Really. I struggle a lot without the help of hints or AI when I'm stuck with the algorithm or the optimisation. When I see a question, I know how to solve and the algorithm appears on my head in a few seconds but since I cannot use AI tools on coding interviews, I feel demotivated to debug my code and just give up depending on the hardness of the problem.

[@HamzaHamouch-d9b]

You're self taught ?

[@reyankhan4702]

Alright, I have decided. I will also do a hundred leetcode problems now.

[@TheCoolestCrocodileEver]

Why are you the best?

[@KayaSilly0]

Should I give this a shot? I don’t want a tech job or anything, and I’m pretty nooby at programming in general, so I’m not sure I could solve the problems!

[@testAccount-eb2ve]

Doesn't hurt to try, may be difficult since some of them require algorithm and data structure knowledge

[@ahmednazar765]

How long did this take you, and for someone who is pretty familiar with CS and programming but hasn't learnt DSA, how long do you think one can learn DSA in?

I still gotta learn a bunch more, like a lot. But it took me like a month or so I would say. If I can do it, you can do it (and probably much faster than me)

I deeply value and greatly appreciate that remark Dr. Teres :)

[@skylo706]

I am really interested in how long you have been coding. You said your unemployed (if it wasnt a joke i wooshed) but I've watched a couple of your videos. I've been an employed programmer for around 6 years now and when I started out like in my first 2 years or so I did a lot of codewars and also tried to solve difficult problems. Nowadays I just can't really do that anymore, like your maze video which was great btw, I guess I just became to stupid by now but your skills look very promising. Do you plan on a specific job like faang or what its called for example? Small edit here: I forgot to mention but if you like to challenge yourself and to solve puzzles basically, you should try and learn some assembly, whatever variant it may be. It's not as difficult as it seems but if you understand it, its a ton of fun (start with 6502 asm, it's extremely easy and great for understanding asm in general. Also you can mod and write games with it for nes and atari 2600)

By the way, Mai Lin leetcode profile isn't actually him according to chinese journalist

[@couldntcareless7884]

I tried doing some leetcode problems myself, and one of the hard ones was finding the median of two sorted arrays. And, I mean, you just take the merge part of merge sort, then get the medium of the new array and that’s it. How is it hard? Finding the longest substring without repeating characters was harder, and that was medium. I find that weird. Can’t complain though l, I solved a hard problem and it took me minutes Edit: did it without an array to merge the given arrays in, to save on memory, that’s noticeably harder.

well while this is pretty cool and i mean, congrats on that, leetcode is meant to be there for a routine, generally speaking 1 or 2 challenges a day is way way better than tryharding 15 one day and then being so exhaused by it that you atop doing these for the whole month lol

I cannot for the life of me figure out leetcode. I am not talking about the code challenge, but the site, the interface and not least, the abomination of a code interface. Doing C, type bool is a thing, apparently, and so is integer overflow, which is to say, this is apparently an error?! WHAT? Furthermore, I cannot for the life of me find the interface you're apparently using and all the interesting problem require paid subscription? I have no idea how you're doing it. Perhaps I am just old...

what if u r like a noobie r there beginners courses ?

[@skylo706]

My personal tip for you would be codecademy. It also has great free courses and it tought me programming 6 - 7 years ago. It gives you small fun projects and guides your hand while introducing you to different things. One project was for example a text based adventure game which taught you about printing stuff to the screen, if and else statements, strings and variables and lists. It is extremely good for a beginner, so give it a try :)

Using ChatGpt is Ethical for solving leetcode🤔

[@Feedv6]

The main purpose is to learn, if you do it with that purpose it is not bad And of course you are not going to ask ChatGTP for the whole solution just to send it in leetcode, you have to try it yourself first.

[@yahira.7031]

​@@Feedv6 The way you learn is by actually trying to solve it by yourself and fail miserably. That way next time you encounter a different problem it'll be easy to get around it. Even getting a "partial" solution can make it really slower to develop those neat problem-solving skills
