How to Start Leetcode as a Beginner

[@BradleyDAllen]

Comment some tips that you know about LeetCode that can help others!

[@user-wl9fz]

May I know what "Must know DS&A" means?? a) Should I first learn all the concepts at once and then start leetcode?? or b) Should I learn one topic and do enough questions on it and then go to the next concept and repeat the process?? I would be thankful if you reply.. (please ignore grammatical mistakes if any)

[@BradleyDAllen]

I would learn topics and solve problems related to those topics. Its all about YOU. You have to learn these things. If it is easier to learn the DSA first then solve problems then do that. If you find something you don't know then you found something to dive into! Stay positive and thanks for watching!@@user-wl9fz

I just signed up for leetcode cause I was told to .. and that introduction was so relatable lmaooooo...

[@swezork]

same..

[@brenoguimaraes7475]

I think that the hardest part (but also a game changer) is to actually get your pen and paper and write out your solving. Very cool content man! Keep it up!

[@BradleyDAllen]

Yes! sorting out all the thinking your doing is a huge game changer when solving problems!!! Thanks for watching! 💪 good luck leetcoding!

[@mennahassanhassan4028]

Completely agree 💯

[@JSON_bourne]

I just finished CS50. I typed super slowly + I remember more when I write things down. I wrote down so much lol

[@Chilli_Tea]

disagree, doing that is a tool but you really need to learn the art of simplifying the problem first

[@chrisrockscode1202]

If your goals for leetcode is for interviews, interviewers will take leetcode questions and make some changes sometimes, so what I’ve been doing is 1. only reading the first sentence 2. then come up with all the clarifying questions that I can come up with on my own 3. Read the rest of the problem to see how close my guess was 4. Then problem solve to make sure your solving the right question in the interview Do this will give practice for thinking about edge cases, and if you gotta gotta gotta talk out the thinking process… I haven’t seriously been interviewing, but soon will be. Thanks for the vid!

[@BradleyDAllen]

Leetcode is a tool!!!! Use it the way it works for you best. Thanks for watching 💪

[@saikrishnavadali05]

1. Learn data structures and algorithms (learn space and time complexities as well) do this before you start leet code 2. First, read and understand the problem completely and clearly...Don't jump immediately to code as soon as you get a thought in your mind. Don't touch the keyboard until you read the description clearly.. This will prevent you from missing some of the contents of the problem to be solved 3. Even before coding.. Take pen and paper and write the steps / pseudo code that comes to your mind 4. Include code for edge and null cases also in your solution 5. If you have already solved a few questions before try to use those learnt approaches in your future problems 6. Know the space and time complexity of your solution. Write it in comments in your solution 7. For success Be Consistent. Don't copy paste the solution.. 8. The main reason for leetcoding is to become the best in data structures and algorithms... To become great in problem solving and to clear coding interviews easily... So don't copy paste solution in the portal.. Think and solve

Thank you so much for sharing this Bradley. I am a full stack developer with 2 years experience but i am struggling to solve leetcode problems, i want a clear explanation of how to solve a leetcode problem and i came accross to a right tutorial, thanks again.

[@artyCrafty4564]

But why you want to solve Leetcode even after being employed as a full stack developer ? Are you planning to apply for other companies ?

[@vamsikrish404]

@@artyCrafty4564 i have 4 years of exp as a software developer, i too find it hard to solve leet code as i have very less knowledge on DSA. In my case, i do contracting jobs, in which they never ask for dsa's in their interview. I want to get into full time but without no dsa knowledge, idk what to do!

[@noahg2]

This is by far one of the best videos I've seen related to leetcode, thank you very much for making it. I am a beginner and I want to know what if I wasn't able to solve the problem in my head at first? I usually look up for solution and that solution makes sense for that moment and after a week I look back at the problem and I feel like I didn't came up with this. How to tackle this one? this is the hardest part for me.

[@BradleyDAllen]

Glad it was helpful!

[@xenotion3650]

I don't think I've seen any video mention this but how WELL do you have to know DSA? A DSA course at a college would give sufficient enough knowledge but to what extent should one know? And should you be able to impelement this DSA in any desired language before start leetcoding? One could know how a DFS/BFS work but not know how to implement it.

[@BradleyDAllen]

I believe that you must know DSA enough to be able to visualize how it is structured in your mind. Then be able to think about doing operations with input and output. After that you must know how to implement, traverse, and change the data structure to solve the problem using algorithms. For example solving Two Sum: you have to know mentally that a Hashmap uses {key,val} structure. Then you must also know that it does not take duplicates. Then you must implement the solution with you coding language. Hope this helps! Good luck Leetcoding!

[@BradleyDAllen]

College can show you the tools , but you must know how to pick them up and use them yourself.

In my initial days of coding, I was a bit scared of these complex Data Structures and algorithms because what I used to think was that I should learn everything first and then solve the questions. But it didn't help. So started learning while solving questions and then I got to understand why we should use xyz Data structure or algorithm in xyz question and how it's helping with reducing complexity or better handling of data. Thank you for such a great video. It will help many.

[@aot-soldier3603]

Hello quick question. I’m currently about to finish my Data Structures and Algorithms course from my university. The class is mostly theory based and my prof mainly focuses on learning how to build or implement stuff like bst and maps, no real examples on how to use them. We rarely see an assignment that uses the current data structures we’re learning, most assignments ask us how to make the add method for a list adt or a binary tree. Am I screwed?

[@Tiamo6525]

Nice !

dude.. great intro!

[@pralhadagnihotri9503]

Its very useful.. bro

[@gianmarcosalerno1942]

On other tip is to stick with only one topic at a time. If you are trying to do multiple topics at once its hard to learn. Its best to start with the easiest topic and then branch out from there. I only have 140 or so problems solved myself FYI

[@ren97x]

relatable intro bro ahah

[@QK_Engineer]

good stuff!

[@0986rashmi]

I think first you will need to think about the brute force solution for this . Suppose if you know the programming language and base data structures very well suppose if I am a dumb engineer who doesn’t know algorithms then I will first choose to use the stacks to keep all the copy of the node values and print . The next improvement over this is you need to optimise the space so you will have the pointers technique to use and reverse the linked list nodes . This is the way to coming up with solution from brute force to optimal

[@abedtahan2175]

Recently i am solving alot of problems, by reading the question thinking of solutions for a bit and making a logical solutions in my head and not thinking much of the syntax and then getting the answer using chatGPT and then reading the solution that i got from chatGPT and understanding it well. Do you think this is a good practice?

[@BradleyDAllen]

When reversing the list in your practice problem, could you just have an array? Assign each value in the array, and reverse it? Then check that the next int in array is less than previous int? I’m only 6 months In to coding and cs so algorithms and data structures are still kinda new to me.
